Product Introduction

Advantage

• Sturdy and Durable - Galvanized steel roofing sheets are made of quality hot-dipped galvanized sheets. They combine steel strength and protective zinc coating. This makes it long-lasting and can withstand extreme weather conditions. The long service life and great strength are the primary reasons why they are popular among homeowners and investors.

Types of Galvanized Steel Roofing Sheet

• Hot-dip Galvanized Steel Sheet

Hot-dip galvanized steel is made by immersing the steel sheet in a molten zinc bath at about 500 °C to attach a zinc layer to the surface. This is the continuous galvanizing process. It will form a protective zinc layer on the surface so that it has good paint adhesion and weldability. It is the most widely used and cost-effective method to prolong the service life of steel sheets. 

• Electro-galvanized Steel Sheet

Electro-galvanizing, also known as cold galvanizing, uses electrolysis to form a uniform and dense layer on the surface of the metal. The anti-corrosion zinc layer can protect steel parts from oxidation corrosion. Also, it can meet decorative purposes. But the zinc layer of the electro-galvanizing steel sheet is only 5-30 g/m2. So its corrosion resistance is not as good as hot-dip galvanized sheets.

Quality Control

We have our own Physical & Chemical Testing Center Lab to guarantee our product quality. Our test items & instrument fully meet international standards.

Applications

Galvanized roofing steel sheet offers great corrosion resistance and a long lifespan. So it is widely used for industrial, commercial, residential, and agricultural purposes. Its wide applications include makeshift houses, garages, greenhouses, warehouses, barns, stables, sheds, factory plants, commercial buildings, etc.
