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!

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).
