COATING Hot dipped alloy coating (galvanising process). COATING ANALYSIS 55% Aluminum. 43.4% Zinc. 1.6% Silicon (by weight) COATING WEIGHT 150 or 185 gms of alloy per m2 equally distributed between both sides of sheet. COATING THICKNESS 150gm coating = 20 microns (equivalent to 275 gms coating of zinc galvanised) 185gm coating = 25 microns (equivalent to 350 gms coating of zinc galvanised) FINISH Bright aluminum type, with predictably consistent small spangles. Stays bright throughout life. FIRE RATING Non-combustible BS476: Part 4; Class O. CORROSION RESISTANCE At least four times the corrosion resistance of zinc galvanised in most applications. Aluzinc is particularly good compared to galvanised in salt laden and/or polluted atmospheres. HEAT RESISTANCE Excellent heat resistance- will not change appearance until beyond 315 deg C. Can be used to much higher temperatures if “graying” is irrelevant. EMISSIVITY Emissivity figure 0.16 – when new. UNSUITABLE COMBINATIONS Basic atmospheres. Contact with more noble metals or their salts. SALT WATER CORROSION An Aluzinc sheet has withstood eighteen years of constant salt spray at Dungeness Power Station without red rust corrosion at any corner, edge or face. LIFE EXPECTANCY TO More than 20 years in most environments and up to 50 years in the least corrosive FIRST MAINTANCE atmospheres. FABRICATION Aluzinc is supplied in a variety of grades but even the most humble is fully lockforming grade. High strength grades as well as deep drawing grades are available. “PAINTABILITY” Aluzinc is very easy to paint. A particularly smooth surface is available. The pre-treatment is easier and more effective than zinc galvanised. DIMENSIONS Coils 50 kilos – 10 tonnes. Sheets 1 metre – 11 metres. Blanks – All sizes. Slit coil available. THICKNESS 0.4mm thick to 2.0mm thick. WIDTH Standards – 1250mm and 1000mm. slit widths also available. SHALLOW PROFILES Coils, sheets and blanks can be supplied with a number of shallow profiles rolled into the sheet. These profiles serve aesthetic, stiffening and cost saving purposes. TRADITIONAL ‘STUCCO’ FINISH AVAILABLE. PACKAGING Sheet and coil substantially packed on refundable pallets. SL0042
