55%-AL Galvalume steel sheet（GL）

The galvanized sheet produced by our company is coated with a layer of zinc as the main raw material on the surface of the cold-rolled sheet. It is widely used in building materials decoration (composite panels, glass tiles,rolling doors), daily necessities (washing machines, refrigerators,ovens).And packaging containers, etc.

Descripción del producto

PLATED (ALUMINUM) ZINC PLATE

The company has excellent equipment configuration and strong technical force. lt can produce galvanized steel sheets of various specifications ranging from 0.10 to 1.50x700~ 1250 xc. The ultra-thin large zinc galvanized sheets produced by 0.10 ~0.15x1000xc are at the international advanced level. The domestic gap has an incomparable advantage.

Hot dip galvanizing production process:

Raw materials(cold rolled steel coil)→unwinding→shearing head and tail→walding→lye washing→lye scrubbing→electrolytic degreasing→water scrubbing→hot air drying→inlet looping→reduction annealing→hot dip galvanizing→zinc layer control(air knife)→cooling→finishing→stretching and bending straightening→passivation→drying→export looper→unloading→steel weighing →packaging→instock

CATEGORY OF STRUCTURES OF CLAD LAYER

Classification item	Category	Code
Types of clad layer	Zinc clad layer	Z
	Zinc-iron alloy's clad layer	ZF
Patterns of clad layer	Clad layer with uniform thickness A(g / m²) / B(g /m²)(A=B)	A/B
	Clad layer with different thickness A(g / m²)/ B(g / m²)(A≠B)
After negotiation between the supplying and demanding parties, the code of equal-thickness plating can be expressed by the sum of the weights of both sides, A is the weight of plating on the outer surface of the steel strip or the surface plating on the steel plate (g/m²); B is the weight of plating on the inner surface of the steel strip or the weight of plating on the lower surface of the steel plate (g/m²).
