Product Description

Product Introduction

Hot dipped galvalume steel coil have a smooth and silver-color spangle surface. The special aluminum and zinc coating structure makes it have excellent corrosion resistance, good heat resistance, good adhesion between the coating and the paint film, good processing performance of punching, cutting, welding, etc.

Product Specification & Features

Hot dipped galvalume steel coil have the following advantaged features：

1.Heat reflectivity
Hot dipped galvalume steel plate have a high heat reflectivity, twice than the galvanized steel sheet, used as a material for heat insulation.

2.Heat resistance
Aluminum-zinc steel plate can withstand high temperatures of more than 300 degrees Celsius, which are widely applied in chimney pipes, ovens, illuminators and fluorescent lampshades.

3.Corrosion resistance
The corrosion resistance are effected by the protective function of aluminum. When zinc break, aluminum will create a dense layer of aluminum oxide, which prevents corrosion-resistant substances from further corroding the interior.

4.Economic practicality
The area of the galvalume steel plate is more than 3% larger than that of the galvanized steel sheet with the same weight and the same coating thickness because the density of 55% AL-Zn is lower than that of zinc.

5.Easy to paint
The aluminum-zinc plate have excellent adhesion, which can be painted without pre-treatment.

Quality Control and Self-inspection

WITOP steel have the advanced testing equipment and professional team. WITOP steel strictly control the quality on each step of production, including inspection on raw materials, product’s thickness and width test, alu-zinc coating test, T-bend test, impact test, tensile test, salt-spray test and package testing on exported steel coil, which ensures its integrated performance and quality.
