Zinc-alum coated steel coil – is zinc and aluminum alloy coated steel, represents a significant improvement on the traditional zinc coated galvanized steel. Zinc-alum coated steel has been widely accepted and has the major share of the steel building products market. Zinc-alum coating steel has been formulated to give a significantly longer service life than galvanized coating. This is of particular value in where the prevailing winds carry corrosive salt laden air many kilometers inland. The resulting alloy coating enhances corrosion resistance, making it ideal for such application as roofing and cladding. Zinc-alum coating is produce a similar process to that used to manufacture galvanized steel. While both products have steel base, galvanized steel has a coating of 100% zinc, whereas zinc-alum coated steel has an alloy coating of 43.5% zinc, 55% aluminum and 1.5% silicon. Features: a) has superior longer term corrosion resistance in most atmospheric conditions. b) Has a finely spangled silvery matt finish. c) is readily paintable using good quality primers and water-base acrylic topcoats. d) Performs exceptionally well in area not regularly washed by rainwater (heavy drainage area).
