Galume Sheet

GALUME is the trade name for a sheet steel product with a highly corrosion resistant coating containing nominally 55% aluminium and 43% zinc, by weight; the balance, primarily silicon, is used to effect excellent adhesion to the steel substrate. This metallic coating, which is applied using a continuous hot-dip coating process, combines the galvanic corrosion protection of zinc with the barrier protection of aluminium. GALUME also displays excellent heat reflection properties, similar to aluminized steels, and is more resistant to higher temperatures than hot-dip galvanized steel. Its will maintain its bright appearance and reflectivity in prolonged exposures at temperatures of 320° C and is not heavily oxidized by continuous exposure to temperatures of up to 650° C. these high temperature oxidation and heat resistance attributes of GALUME enable the potential applications to be expanded beyond the traditional metal building market. In particular, automotive exhaust systems, furnace and oven hardware, and white goods that require heat resistance [ovens, cookers, etc.] also used for Roofing and cliding, pre-painted sheets, air conditioners, refrigerators and ductings etc. are potential applications of GALUME.
