Galvalume Steel Coil


Galvalume steel coil is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. So it is also known as cold galvanized steel.

Product Show

Through electrolytic galvanizing, a uniform and dense zinc layer is finally formed on the surface of the steel, but the mechanical properties of the material are still maintained. Electrogalvanized steel is usually sold in coil or sheet form. EG coil is a kind of material that can be cut, slitted and profiled for other purposes. The steel grade of galvanized steel consists of base metal grade, galvanized (E), galvanized layer type and weight. The electro-galvanized products based on SPCC, SPCD, SPCE, SPCF and SPCG are named SECC, SECD, SECE, SECF and SECG respectively.

The production process of aluminum zinc plating is as follows:
Uncoiling-cleaning-annealing-zinc pot-cooling-air knife-straightening-post-treatment-coiling
Heat Reflection
People use it as a thermal insulation material, and its thermal reflectivity is up to twice that of galvanized steel.
Heat Resistance
Galvanized steel coil has good heat resistance and can withstand high temperatures above 300°C, which is very similar to the oxidation resistance of aluminized steel at high temperatures. Commonly used in chimney tubes, ovens, illuminators, fluorescent lampshades, etc.
Corrosion Resistance
The key to the corrosion resistance of aluminized zinc steel coil is the protective performance of aluminum. Once the zinc is worn, the aluminum forms a dense layer of aluminum oxide, preventing further internal corrosion.
Economy
The density of 55% AL-Zn is smaller than that of Zn. Therefore, when the coating weight and thickness are the same, the area of the aluminum-zinc plated steel sheet is 3% larger than that of the galvanized steel sheet.
Easy to Paint
The coating material on the aluminized zinc steel plate has excellent adhesion, and can be directly coated with tar on advertising boards and common plates without pretreatment such as weathering.

Galvanized Steel Coil

Spangle is formed during the hot-dip galvanizing process. The size, brightness, and surface of spangles mainly depend on the composition of zinc layer and the cooling method. According to the size, it includes small spangles, regular spangles, big spangles, and free spangles. They look different, but the spangles almost will not influence the quality of galvanized steel. You can choose according to your preference and purpose.
