Roof and Wall Cladding
INTERTOUCH profiles are now available in Galvalume. A significant advance in protective coating for sheet steel roofing and cladding. Galvalume is a zinc aluminium coated sheet offering high corrosion resistance with a clear resin coating.
The alloy coating comprises of 55% aluminium, 43% zinc and i.5% silicon. This coating combines the superior barrier protection of aluminium and the sacrificial cut edge protection of zinc.
Galvalume is available in coating class AZ150 (150 gm/m2 minimum coating mass) and offers 2-4 times the service life of traditional galvanized steel in similar coating thickness under severe environment conditions.
Galvalume profiles are supplied with an optional organic colour coating in silicon modified polyester or fluoropolymer (70% Kynar ® 500).
These colour coated profiles exhibit excellent life to first maintenance in excess of 20 years.
Galvalume is a registered trade mark of BIEC international, USA.
