HONGSHENG'S Galvalume is a highly corrosion resistant coated steel with the addition of aluminium (passivation protection) to zinc, with a composition of 55% aluminium, 43.5% zinc and 1.5% silicon, which combines the barrier protection and extended durability of aluminium with the galvanic protection of zinc.
Galvalume has excellent resistance to atmospheric corrosion. It's corrosion resistance is 2-4 times that of galvanized steel, and has the high temperature corrosion resistance of aluminium, smooth surface and good appearance.
The Galvalume(aluminum-zinc coated) steel containing 55% aluminum was developed by Bethlehem Steel Corporation of the United States and has been officially put on the market since 1972. Its core lies in applying an aluminum-zinc-silicon alloy to the steel sheet surface through a continuous hot-dip process, combining the durability of aluminum and the galvanic protection properties of zinc, and has gained industry recognition with its excellent performance.
SPANGLES
DX51D | 1.0917
Grade DX51D is a machine folding grade and is suitable for simple craft forming work as well as for the production of simple profile shapes. DX51D is generally applicable in mechanical and structural engineering, e.g. for ventilation technology, air conditioning systems, switch cabinets, electrical industry, household appliances and steel furniture.
DX52D | 1.0918
Grade DX52D is a drawing grade and can be used for drawing, stamping and profiling difficult parts.
DX53D | 1.0951
Grade DX53D is a deep-drawing grade that meets high demands on formability and is particularly suitable for the production of difficult profiles with greater thicknesses.
