Kalzip from yesterday to today.

Kalzip, initially a product of the American company Kaiser Aluminium, was established in Germany in 1967. At the same time the production and marketing of Kalzip began in Koblenz.

In 1968, the first Kalzip roof was installed at the Nuremberg Congress Hall. Due to the popularity of the product, Kalzip quickly developed into a major player as a manufacturer of metal roof coverings.

This was followed in 1972 by a move within Koblenz to a new, larger location, where the headquarters are still located today. By 1974, over one million square metres of Kalzip profiled sheets had already been installed.

Today, after 50 years, Kalzip is proud of its long history and its involvement in numerous impressive buildings, such as the “Stadio delle Alpi”, in Turin that was opened in 1990 for the Football World Cup, the “Barajas Airport” in Madrid with 232,000 square metres of Kalzip profiled sheets and the “King Abdullah Airport” with a roof area of 350,000 square metres.

Kalzip gained worldwide attention in 2016 when the sarcophagus for the damaged Chernobyl nuclear power station, was clad with 168,000 square metres of Kalzip sheets produced in stainless steel.

Today Kalzip is a member of the Donges Group. The Donges Group is the leading supplier of bridge and steel constructions as well as roof and facade systems in Europe.

Sustainability

Kalzip sustainability focuses on aluminium itself – a material that can be recycled as often as required and has sufficient reserves. It makes a significant contribution to protecting buildings effectively and over decades against external influences and to maintaining their value in the long term.

Thanks to its durability and excellent recycling properties, three-quarters of the aluminium produced worldwide to date is still in use.

One of the outstanding properties of the material is its resistance to weathering and the inherent durability. This creates reassurance, especially when there are high demands on the use of buildings, e.g. at airports, or in aggressive environments, such as near the coast.

  • Third most common element of the earth’s crust
  • Aluminium, once produced, delivers products for generations through recycling
  • It can be recycled without restriction
  • Up to 95% of the energy required for production is saved through recycling
  • Roof and facade products are durable, maintenance-free, deconstructable and therefore recyclable
  • Highly corrosion resistant
