Kalzip aluminium roofing and cladding systems have been used extensively in construction over the past 40 years and continue to be the preferred choice for highly demanding environmental conditions, such as industrial, city centre, marine and airport locations. One of the unique features of Kalzip is the use of highly durable clad alloys for the additional protection of the core material. This outer cladding or plating gives Kalzip outstanding long term resistance to corrosion.

Testing of the material’s capabilities has been ongoing throughout Kalzip’s history. Most notably, in 1997, The Federal Institute for Material Research and Testing (BAM) in Germany published a test report, BAM-Ref:  1.4/11416 N1 setting out the results of test carried out in 1993 on a series of Kalzip installations, including on the roof canopy of the Congress Hall in Nuremberg. Here Kalzip 305 profile was installed in 1968 and at the time of testing was approximately 25 years old.
