Galvalume Steel Coil prime cold rolled steel sheet in coil galvanized steel coil

Galvalume Steel Coil prime cold rolled steel sheet in coil galvanized steel coil

DX52D+AZ/DX51D+AZGalvalume/galvamized Steel Coil is uniquely smooth, flat and gorgeous star flower, and the base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of aluminum-zinc plate can be up to 25a, and it has good heat resistance and can be used in a high temperature environment of 315°C; the adhesion of the coating and the paint film is good, and it has good processing properties, and can be punched, cut, welded, etc.; The surface conductivity is very good.

The coating composition is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon in weight ratio. The production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminized sheet, and it is a continuous molten coating process. The galvanized steel sheet with 55% aluminum-zinc alloy coating has better corrosion resistance than galvanized steel sheet of the same thickness when exposed to the same environment on both sides. The 55% aluminum-zinc alloy coated aluminum-zinc steel sheet not only has good corrosion resistance, but also the color-coated products have excellent adhesion and flexibility.DX52D+AZ/DX51D+AZGalvalume/galvamized Steel Coil can be customized according the custom’s different requirments, such small spangle ,zero spangle ,big spangle ,checkered ,zinc coating, they can meet all the customer’s different needs.

2) PPGI Corrugated Steel Sheet Galvanized Colorful Metal Plate

PPGI roofing sheet is a good building material, mainly used for guardrail, floor and other buildings, such as airport
terminal, railway station, stadium, concert hall, grand theatre, etc. According to different application requirements, the
profiled steel sheet can be pressed into a wave type, a T type, a V type, a rib type and the like.
