185g/m2 COATING

185g/m2 coating = 25 microns (equivalent to 350g/m2 coating of zinc galvanised), hot dipped alloy coating (galvanising process) 55% Aluminium. 43.4% Zinc. 1.6% Silicon (by weight) giving 185 grammes of alloy per m2 equally distributed between both sides of a sheet, which gives between 6 and 20 times the corrosion resistance of zinc galvanised in most applications. Aluzinc is particularly good compared to galvanised in salt laden, acidic and polluted atmospheres.

185g/m2 is specified for use on all petrochemical/chemical applications.

The finish is a bright aluminium type, with predictably consistent small spangles. Offered with with special mark and finger print resistant coating. Stays bright throughout life, with excellent heat resistance - does not change appearance until beyond 315˚c. Can be used to much higher temperatures if "greying" is irrelevant.
