40 years and counting
Kalzip aluminium roofing and cladding systems 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 resulting in a BBA-certified life expectancy in excess of 40 years.
Testing has been ongoing throughout Kalzip’s history and the material’s capabilities have recently been independently authenticated by virtue of testing undertaken by Germany’s Federal Institute for Material Research and Testing (BAM). BAM’s thorough examinations and assessments have been taking place for more than 40 years in three types of aggressive environment - marine, urban and industrial.
Tests on all three roof installations, carefully selected for their different atmospheric conditions, have been carried out intermittently throughout the 40 year period, enabling comprehensive documentation of progress corrosion.
These latest findings by BAM formally corroborate the fact that even after 40 years of exposure to potentially corrosive industrial pollutants and atmospheric attack, the base material of a Kalzip roof sheet - and therefore its ability to perform - remains fully functional.
The Kalzip roof system in its entirety has achieved third party certification by the BBA in the UK and is globally recognised by the German Zulassung, French Avis Technique and Factory Mutual quality standards.
