Galvalume®Coated Steel
TRACDEK® profiles are available in both ribbed and flat panels to give a variety of finishes for attractive roofing and cladding of domestic, commercial and industrial applications. The profiles are available in the following standard finishes:
- Organic coated pre-painted Galvalume® high tensile steel with silicon polyester or fluoropolymer (PVF2) coating.
- Organic coated pre-painted galvanized steel with polyester coating.
- Organic coated pre-painted aluminum with fluoropolymer (PVF2) coating.
- Bare Galvalume® and galvanized finishes.
All the roof and wall coverings are supplied with custom accessories such as flashing, cappings, futters, trims, fasteners, etc. which are formed out of the same substrates and coatings as the roof and wall covering panels.
TRACDEK® Galvalume® Plus
TRACDEK® profiles are now available in Galvalume® Plus. A significant advance in protective coating for sheet steel roofing and cladding TRACDEK® Galvalume® Plus is a zinc-aluminum coated steel offering high corrosion resistance with a clear resin coating.
The alloy coating comprises of 55% aluminum, 43% zinc and 1.5% silicon. This coating combines the superior barrier protection of aluminum and the sacrificial cut edge protection of zinc.
TRACDEK® Galvalume® Plus is available in coating class AZ 150 (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.
TRACDEK® 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.
