Galvalume steel coils

Aluminum-zinc plated steel sheet has a characteristic smooth, flat and ornate starburst surface with a silver-white base color. The special coating structure gives it excellent corrosion resistance. Aluminum-zinc-plated plate normal service life of up to 25a, heat resistance is very good, can be used for 315 ℃ high temperature environment; plating and paint film adhesion is good, has good processing performance, can be stamping, shearing, welding, etc.; surface conductivity is very good.

Product Advantages

1, corrosion resistance: aluminized zinc plate has a strong corrosion resistance, the normal service life of up to 25 years, 3-6 times longer than galvanized sheet, and stainless steel appropriate. Aluminum-zinc plate corrosion resistance from the aluminum obstruction layer maintenance function, and zinc dedication maintenance function. When the zinc in the cut edge, scratches and plating abrasion some of the dedication maintenance, aluminum will constitute an insoluble oxide layer, the performance of the barrier maintenance function. Aluminum-zinc-plated alloy steel coil has been in a variety of different atmospheric environments, for more than 20 years of outdoor exposure test, confirmed that 55% of aluminum-zinc-plated steel cut edge maintenance function, than galvanized steel and 5% aluminum-zinc-plated steel plate for the better.

2, heat resistance: aluminum-zinc-plated sheet has a high degree of heat reflectivity, suitable for roofing materials, aluminum-zinc-plated alloy steel plate itself is excellent heat resistance, can be used for up to 315 degrees of high temperature environment.

3, re-coating: (paint film adhesion) aluminum-zinc-plated sheet can maintain outstanding adhesion with the paint film, no need for special pre-disposal, you can directly spray paint or spray powder.

4, after painting corrosion resistance: aluminum-zinc coated sheet itself after partial painting and baking, unpainted some of the corrosion resistance is reduced by very little. Function greatly superior to electroplated zinc and galvanized sheet and hot-dip galvanized sheet.

5, processability: (shear, stamping, spot welding, seam welding) aluminum-zinc-plated steel sheet has outstanding processing capabilities, can be stamping, shearing, welding, etc., the coating has a very good adhesion and impact resistance.

6, conductivity: aluminum-zinc-plated plate appearance through a special wax coating disposal, can satisfy the needs of electromagnetic shielding.
