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.

Product Description

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).

55% Galvalume steel coil is a remarkable product in the world of construction and manufacturing.

1. Composition and Coating
The "55%" refers to the aluminum content in the coating. This precise amount of aluminum in the galvalume coating provides excellent corrosion resistance. The zinc - aluminum alloy coating forms a protective layer over the steel substrate. This layer not only shields the steel from rust and corrosion but also gives the coil a long - lasting lifespan, making it suitable for both indoor and outdoor applications.

2. Physical Properties
It has high - strength characteristics, enabling it to withstand various mechanical stresses. The steel coil is highly formable, which means it can be easily bent, cut, and shaped into different forms required for construction projects. Whether it's for roofing, siding, or other structural components, its flexibility in fabrication is a great advantage.

3. Aesthetic Appeal
In addition to its functional properties, 55% galvalume steel coil offers an aesthetically pleasing finish. It has a clean, metallic look that can enhance the visual appearance of any building or structure. It is available in different finishes, allowing architects and builders to choose the one that best suits their design concepts.
