It gets under our skin – knowing how many rousing sporting events take place under the roofs of the stadiums.

Above all, the strong emotions that are unleashed underneath. Boundless fighting spirit, the victory as a great goal in front of one’s eyes after years of sweaty preparation, respectful encounters between nations from all over the world, the euphoric cheering, the fans cheering along.

As long as the sport lives on in these stadiums, we will remain a part of it.

World Cup semi-final 1990 – A match for the history books

Home advantage in Turin:
How to score as an international company thanks to innovative production.

Germany defeats England in the classical match. Turin becomes a sea of black-red-gold jubilation in 1990, with a success in the Stadio Delle Alpi even before the final result after a penalty shoot-out.

The Stadio Delle Alpi in Turin made history in 1990. On the one hand as the venue for the classic football match between England and Germany, and on the other hand in Kalzip’s corporate history. This is because the 25,000 m2 aluminium roof construction we realised for the stadium was the first project in Europe to use a mobile roll former and the associated innovative on-site production – the second in the world.

The encounter between the two teams in the semi-finals was a real football drama that the German national team won in the legendary penalty shoot-out. Almost 22 million viewers and around 30,000 German fans in the stadium witnessed a real nail-biter.

Delle Alpi – a worthy venue

What few people know: There was already a German success in the Delle Alpi before that, because the roof construction we developed is a real feat in terms of architecture and statics and gave the stadium its striking silhouette.

The high-quality and extremely versatile material aluminium and the development competence Made by Kalzip are the reason why we, as the market leader, are able to demonstrate our competence in many international stadiums and sports facilities, among others. Because it is precisely in these construction projects that unusual shapes, enormous loads and static challenges are the order of the day. And that is precisely our discipline.

Home advantage on the construction site

As an international company and market leader, we made a phenomenon familiar to many from football our own thanks to an innovative manufacturing process we developed ourselves: Home advantage. For the first time in Europe, we produced the required standing seam profiled panels on site at the construction site. This meant that many logistical and technical requirements were extremely optimised and coordination processes were shortened. On-site production is a tactic that we still follow today for national and international buildings.

Perseverance, team spirit and success are factors that play an enormously important role not only in professional sport. In our construction projects, too, these are decisive qualities for optimal project execution. We prefer to leave excitement, passion and drama to the sporting duels.

Hoffenheim – Leverkusen: A goal, that changes a lot

A place for new technology:
PreZero Arena in Sinsheim brings innovations for stadium construction and sports

18 October 2013 will have a decisive significance in Bundesliga retrospectives for a long time. The stadium, which was only four years old at the time, experienced a historic moment.

Stefan Kießling, former German national player, scored the 2-0 goal in the match between Hoffenheim and Leverkusen. The scandal: The ball flew through a hole in the outer net and into the goal, paving the way for trend-setting rule changes in professional football. But Sinsheim was also the scene of technical innovations when the stadium was built.

PreZero Arena – a step to the future

Opened in 2009, the PreZero Arena is considered one of the most modern and attractive stadiums in Germany thanks to its aerial, bright architecture. The 30,150-seat arena was completed in just 24 months. A special highlight is the complex, three-dimensionally structured roof construction, which does not simply sit as a “lid” on the tiers but almost floats above the stands. The construction, consisting of 40,000 square metres of plastic membrane, is extremely filigree and weighs only 3,400 tonnes. We at Kalzip were able to play a decisive role in this engineering masterpiece and contribute to its success with our know-how in innovative manufacturing processes. The steel building underneath was also our first collaboration with Donges SteelTec – today a symbiosis under the roof of the Donges Group, which enables challenging constructions worldwide from a single source.

The small curved radii of the slim construction, which we were able to realise in this form for the first time by curving our X-Tail sheets, were particularly challenging in Sinsheim. The result of the special roof construction: the structure does not need any supporting pillars at all. For the spectators, this means that a clear and excellent view is guaranteed from all seats.

Best view – at least for the fans

This is how many fans see what had been missed by referee Felix Brych during the match between TSG Hoffenheim 1899 and Bayer 04 Leverkusen. Bayer striker Stefan Kießling heads the ball against the outer net in the 70th minute, but the ball flies through a hole in the net into the goal. Kießling, who already disappointedly turns away after his header, lets himself be infected by the goal celebration of his team mates. Referee Brych mistakenly calls a goal. The result: heated discussions and far-reaching consequences for football. The introduction of goal-line technology and video evidence can be seen as a direct reaction to this legendary phantom goal.

So Sinsheim is a place of change. The phantom goal has shown that even football, the most followed professional sport, is not perfect and can be constantly improved. Like us, the players involved in professional sport strive for regular optimisation in order to present a perfect result. The rule adjustments that are still in force today also characterise the fairness and team spirit of professional football – qualities that are also 100% lived in our work and taken to heart in every one of our construction projects.

The last step to the Superbowl 2010: A game heals wounds

Never give up!
The true meaning of the Caesars Superdome

New Orleans is the home of the Caesars Superdome, one of the most famous and iconic stadiums in the USA, with well over 70,000 spectators experiencing various superlative sporting events over the years.

But the Superdome is more than that: back in August 2005, despite a badly damaged roof due to Hurricane Katrina, the Superdome became the last place of refuge for over 30,000 evacuees and a symbol of hope. With the largest stadium refurbishment project in US history, Kalzip played a major role in shaping the history of the Superdome.

Caesars Superdome in New Orleans – last sanctuary for thousands

A stadium has many synonyms. For some it is their fortress, for others their temple, some even affectionately call it home. In 2005, these synonyms became a bitter reality for many US citizens, when Hurricane Katrina struck, New Orleans became the scene of one of the most devastating natural disasters in the history of the United States. Countless buildings were severely damaged and many people lost their homes. The Superdome – usually the venue for the New Orleans Saints football team plus numerous Super Bowl events and concerts – became the last refuge for over 30,000 people, and for many, the arena offered a last place of hope.

We don’t give up – the Superdome gets an innovative façade

The Superdome was also severely damaged by the hurricane. This was the starting point for a gigantic refurbishment project. True to the sporting motto “Never give up”, all forces were combined. We are proud to have made a decisive contribution to this mammoth project with our technical expertise. It took only 13 months to reopen the Superdome after renovating the roof and the interior. Creativity was needed to restore the original appearance of the world’s largest dome and at the same time be prepared for extreme weather events. Kalzip developed our FC façade system, which sets new standards in the areas of flexibility, ease of installation and cost-effectiveness. This bi-directional facade system allows the aluminium panels to be installed from top to bottom and from bottom to top, as well as laterally in both directions. This functionality enabled us to remove the damaged façade and easily replace them with the Kalzip FC façade panels without affecting the overall appearance of the façade. At the same time, the clip connection ensures an extremely high wind load resistance for the façade. With approximately 34,000m² of the Kalzip FC Façade system installed, we have proven: We do not give up and embrace every challenge!

Only 5 years after Katrina:
The Saints send New Orleans into ecstasies

This spirit still has had a defining influence on the sporting events of the Superdome today. In 2009, it inspired the hometown New Orleans Saints to win their first NFC Championship Game against the Minnesota Vikings to reach the Super Bowl in Miami for the first time. They also won this game with a score of 31:17. On their return to New Orleans, the Saints were welcomed home by 70,000 enthusiastic fans.

This story that underlines the importance of sport for the people of the city. Sport brings people together and helps them to put bad events behind them. In sport, too, there are often setbacks and serious disappointments, but these only make athletes and fans stronger. At Kalzip we share this passion, because even in difficult times, there is only one thing to do: stand up, tackle and above all: never give up!

Olympics 2021 in London – faster, higher, stronger

The right technique as a prerequisite for the perfect wave

Exactly one year before the opening of the 2012 London Olympics, the time had come: The London Aquatics Centre was opened as the central venue for the six swimming disciplines. True to the Olympic motto “Faster, Higher, Stronger”, the completion of the aquatics arena located in the Queen Elizabeth Olympic Park was also a world-class achievement.

The focus of the Olympics is on the athletes. They compete for Olympic gold in over 300 competitions. The fascination of the Olympics is to achieve the best performance through pure will, dedication and passion. At the same time, it is an incredible challenge that must be overcome. With the award of the construction contract for the roof of the Aquatics Centre, Kalzip were also played their part in this festival of sport.

Kalzip on the Olympic path

London 2012 was calling, and we were ready. Our planning for the 2012 Summer Olympics was not unlike that of a top athlete. Participation in the Olympic Games requires long and detailed preparation. If you want to take part, you have to train intensively and constantly improve. Hurdles have to be overcome and boundaries crossed.
Only the best reach the finish line and see the Olympic flame. To be at the top, you need the greatest fighting spirit and the best technique. While the best swimmers in the world worked intensively on their technique and condition, it was up to Kalzip to present them with the best possible venue.

Triumph after long and intensive preparation

This would not have been possible without perfect preparation. Absolute precision was taken into account right from the initial planning stage. With the help our innovative 3D design technology, the complex roof construction was conceived to guarantee one hundred percent accuracy in both the manufacturing and installation process. The was carried out using our flexible Kalzip XT system, which allows be-spoke roof shapes to become a reality. Our roof stands out as a key design element on the 160m long, 80m wide and 45m high facility.
The design is based on the specific characteristics of water sports and visually showcases the water sports arena in all its glory. Thus, the wave-shaped roof geometry approx. 1040m² was inspired by the idea of a swimmer breaking through the water. Zaha Hadid served as the lead architect for the project. In 2004, she became the first woman to receive the Pritzker Prize, the world’s most prestigious architectural award. Her kinetic architectural style is perfectly reflected in the flowing wave of the London Aquatics Centre, making the architect, who died in 2016, immortal to this day.

“Inspiring a Generation”

The legacy the 2012 London Olympics epitomises our approach not to rest on our laurels, but to continuously improve and strive for the best possible performance. As an Olympic role model the US swimmer Michael Phelps, despite several Olympic victories in 2004 and 2008, at the 2012 ‘games’ Phelps became the most successful athlete at the games with four gold and two silver medals. With a total of 23 gold medals won in total, he truly inspired an entire generation. We are proud to be part of this inspiration and can’t wait to create more fascination with our future building projects.

Südtribüne Hockenheimring – a racetrack at the pulse of time

Südtribüne Hockenheim – A view of a legendary race track as well as an impressive event location

Located south of Mannheim, the Hockenheimring is a world-famous and highly regarded motorsport circuit. Formula 1 greats such as Michael Schumacher and Lewis Hamilton have impressed spectators here with spectacular performances. The south grandstand provides the perfect view. Under the spectacular Kalzip roof, the spectators are part of the action even in heavy rain. Open airs remain just as unforgettable as the Mercedes debacle of 2019.

From the first motorbike race in 1932 to the construction of the Motodrom in the 1960s and, for the time being, the last Formula 1 race on German soil in 2019 – the Hockenheimring has shaped various generations and turned spectators into frenetic motorsport fans. Formula 1 came to Hockenheim for the first time in 1970. Over 100,000 spectators witnessed the victory of the tragic Formula 1 legend Jochen Rindt. To this day, he is the only world champion who was awarded the title posthumously due to a fatal accident in Monza one month later.

Less track, increased racing feeling – massive south grandstand thanks to Kalzip

Until 2001, the course was 6.8 kilometres long. Large sections were driven through the forest and were therefore not visible to the spectators. The attractiveness of the track for both drivers and spectators was increased enormously through renovation measures to the tune of around 62 million euros. Today’s well-known 4.5km race track guarantees exciting overtaking manoeuvres with its tight combinations of bends. The best view is from the south grandstand, which is located at the height of the start/finish straight. The structure, built in 2003 by Kalzip and Schüngel Metal Systems GmbH, offers an impressive view of the world-famous Motodrom. The process of creating the structure was also impressive, as the curved Kalzip profiled sheets had to be attached to the façade. The roof and façade thus merged into one – a challenge that was demonstrably mastered.

Rain chaos at Verstappen’s 2019 triumph

Weather conditions can have a decisive influence on a Formula 1 race. Unpredictable rainfall in particular makes for spectacular racing events. This is what happened at the last German Grand Prix to date. Four safety car phases were necessary due to various spins and accidents. Due to the clever choice of tyres, it was Max Verstappen in the Red Bull who took the day’s victory. The man of the day, however, was Sebastian Vettel. Starting from 20th place, he finished the day in 2nd place after a very strong performance. The Mercedes drivers Lewis Hamilton and Valtteri Bottas, on the other hand, put negative exclamation marks on the day. Botched pit stops, time penalties and driving errors resulted in a lot of frustration and no points.

The spectators were able to watch this rain battle from dry ground thanks to Kalzip. The roof of the 30m-high south grandstand merges directly into the façade and, with its roller-rounded tracks, ensures not only an iconic design but also racing enjoyment in all weathers.

Hockenheim continues to host special events – DTM finale in October

However, it is not only the top class of motorsport that provides emotions. True to the motto “More than Racing”, the Hockenheimring is particularly versatile when it comes to concerts. Whether AC/DC or Ed Sheeran – hundreds of thousands of fans are always thrilled. But you can’t do without the roots

Estadio BBVA Bancomer – Home of latin american football-dreams

La pasión del fútbol – Kalzip works in Mexico for the first time

If you are looking for passionate football fans, you will quickly find them in Mexico. In the Estadio BBVA formerly known as the Estadio BBVA Bancomer, the home ground of CF Monterrey, up to 53,500 spectators often celebrate a football festival.

It quickly becomes clear that the distance between the pitch and the stands is limited to the minimum set by FIFA. The direct experience of the game as well as the impressive construction of the Kalzip® standing seam roof have shaped the Latin American football landscape since the opening in 2015.

The Steel Giant

With a size of 277×232 metres and a circumference of 800 metres, it is understandable why the stadium is also called “El Gigante de Acero” (Engl.: The Steel Giant). The imposing sight is further enhanced by the mountain views in the background. Without the vision of the Architectural firms Populous together with the Mexican firm VFO, this realisation would not have been possible. A look at the hot and unpredictable climate of the region underlines that not only do the players of the local CF Monterrey face challenges, but also all those involved in the construction process.

Despite all challenges – Kalzip impresses with quality and performance

The weather conditions typical for the region, such as wind, heavy rain and strongly fluctuating temperatures, had to be considered in the initial planning and design. With the Kalzip® aluminium standing seam roof system, we were quickly able to offer a solution for the 51,000m² roof*. Thanks to our patented clip system, our roofs can easily withstand the given climatic conditions as well as comprehensively meet the highest safety requirements.

Within the construction period of just under four years, we delivered more than 40 containers in 16 shipments and built our own production yard on site. Since our range and material offer limitless design potential, the architects were able to give free rein to their vision. The result: a design that reflects both the history of the region and the mountainous landscape, but also a sustainable design, as the Estadio BBVA received a silver certificate from the Leadership in Energy and Environmental Design [LEED] organisation.

*The stadium was opened in 2015 with a capacity of 51,000 people, making it the fourth largest in Mexico. The owners soon added more seats, expanding the capacity to 53,500 in 2016

Commitment up to the last minute

The Club de Fútbol Monterrey, one of Mexico’s most traditional clubs, plays its home games in the Estadio BBVA. A club which, in keeping with the construction of the stadium, defies every challenge. This is what happened in the first match in the new stadium on 11 August 2015, when the team was already trailing 0-2 after 25 minutes against CF Pachuca. With will, passion and the cheers of the crowd, the game was turned around in the 63rd minute. Even when they conceded another goal to equalise 3-3 in the 69th minute, the home side could not be stopped. Supported by the fans and with the irrepressible striving for success, they scored the winning goal in the last minute to make it 4-3. There could not have been a more spectacular first home game.

With this attitude, the club celebrated the greatest success in the club’s history in 2019. The second leg of the 2019 CONCACAF Champions League final was played at home. After a 1-0 win in the first leg, and with a 1-1 draw in the second leg Monterrey won the final 2-1 on aggregate.

“El Gigante de Acero” finally became a football temple – also thanks to Kalzip.

Ethiad Stadium Manchester – Location of a real thriller

Kalzip helps Manchester City to win the championship

After Sydney won the bid to host the 2000 Olympic Games, Manchester successfully bid to host the 2002 Commonwealth Games, a trigger for the creation of the City of Manchester Stadium.

The stadium was designed by the Arup Group and built by John Laing, whose work culminated in the opening of the stadium and the opening of the Commonwealth Games on 25 July 2002. The City of Manchester Stadium hosted and staged all the rugby matches as well as all the athletics events of the Commonwealth Games.

Kalzip creates change

After the Commonwealth Games, the stadium has become a legacy for the City of Manchester that is viable, iconic, and a catalyst for regeneration. The City of Manchester Stadium was converted into a football stadium to be used by Manchester City Football Club.

Kalzip contributed significantly to the distinctive and impressive design of the original roof of the City of Manchester Stadium with 18,000 m2 of Kalzip aluminium standing seam profiled sheets.
Kalzip were also involved in the conversion of the City of Manchester Stadium into a football stadium. The bowl, which first covered three-quarters of the stadium in a horseshoe shape, was completed for the football stadium. Here too, Kalzip aluminium profile sheets (embossed with a stucco pattern) was used to complete the ‘circle’ the roof to provide the “Citizens” of Manchester with an unforgettable football experience. The complexity of the roof design demanded absolute accuracy in both the basic framework and the fixing/fastening of the roof sheets.
The column free cable-net roof structure enables spectators from all seats to view the pitch or arena without obstructions. The resulting views of the stadium from the stand, with the sweeping arcs of the lower tiers and the roof, are exhilarating

The roof is divided into different segments or bays. In total, there are 53 bays that complete the roof of the Stadium, many of which vary in size to suit the elliptical form.

Kalzip creates homes of championships

That our products and innovation can be described as masterful has long been beyond question. But in the 2011/2012 football season, Manchester City also benefited from Kalzip Aluminium. On the penultimate matchday of the Premier League season, Manchester City were level on points with local rivals Manchester United at the top of the table with both with 82 points. The game on the last match day of the season had to be the deciding factor.
Manchester City faced Queens Park Rangers at their home stadium. However, City could not take advantage of the good starting position for this decisive battle, in the form of a 1-0 lead for Manchester City and a sending off for Queens Park Rangers, so that they fell behind in the second half. Manchester United, meanwhile, led 1-0 against Sunderland FC. It seemed for a long time that Manchester City would have to say goodbye to the championship. Even the fans of the city rivals were already celebrating their championship.

But then the unbelievable happened

Manchester City equalised in the 90th minute through Edin Dzeko to make it 2:2 and then scored again in the final seconds through Sergio Agüero to win the game 3:2 There was no stopping the fans in the stands as they celebrated with their team. The better goal difference ensured that Manchester City would claim the Premier League title for the first time since 1968.

With this attitude, the club celebrated the greatest success in the club’s history in 2019. The second leg of the 2019 CONCACAF Champions League final was played at home. After a 1-0 win in the first leg, and with a 1-1 draw in the second leg Monterrey won the final 2-1 on aggregate.

“El Gigante de Acero” finally became a football temple – also thanks to Kalzip.

We are involved in sports facilities internationally

Stadio delle Alpi in Turin

Built for the 1990 World Cup, the Stadio delle Alpi was home to Juventus Turin for many years and the scene of numerous legendary matches, including the classic Germany-England match in July 1990. The dramatic penalty shoot-out and the match against Argentina in the victorious World Cup final are still unforgotten today.

Etihad Stadium in Manchester

Built for the 2002 Commonwealth Games, the stadium was adapted into a football-only arena a year later and has been home to Manchester City ever since. During this time, the Etihad Stadium has seen the Citizens win 5 English championships and countless big games on the international stage.

Feyenoord Stadion in Rotterdam

The football stadium in Rotterdam, also known as “De Kuip”, is the second largest stadium in the Netherlands with 51,117 seats and is the home ground of Feyenoord Rotterdam. Feyenoord celebrated the greatest triumph in the club’s history by winning the UEFA Cup in 2002 in their own stadium. Probably the most dramatic victory in the Feyenoord Stadium was achieved by France against Italy in the 2000 European Championship final. With a last-second equaliser and a golden goal victory in extra time, the French became European champions.

Tivoli in Innsbruck

Opened in 2000, the “Tivoli” was one of eight venues for the 2008 European Football Championship. European football fans also know the stadium as the venue for various Eurobowls. In addition, the “Tivoli” with its impressive mountain panorama serves as the home ground of the Austrian two-league football team FC Wacker Innsbruck and the American football team Swarco Raiders Tirol.

Estadio da Luz in Lissabon

Although only opened in 2003, the Estadio Da Luz has already served as the backdrop for numerous historic encounters. King Otto sensationally won the European Championship with Greece here (2004), Real Madrid beat city rivals Atlético 4-1 in extra time in the Champions League final after a last-minute draw (2014) and the Champions League final was the venue for FC Bayern München’s third title win (2020).
