Galvanized iron sheet roofing is a corrugated cold-rolled sheet made by cutting and bending galvanized steel sheets. It has the properties of preventing steel from rusting and corrosion, waterproofing, heat insulation, and durability. It is one of the commonly used materials in the construction industry. Features: anti-corrosion and durability, good waterproof performance, heat resistance, cold resistance, and stable physical properties.
Advantages
Light reflection
Galvanized sheet has stronger light reflection ability and greater reflectivity.
Heat resistance
Can be used for a long time and can be used at high temperature for a long time without discoloration.
Mechanical properties
Mainly manifested in yield strength, tensile strength and elongation.
Corrosion resistance
It has excellent corrosion resistance and longer service life than other steel plates.
Production process of galvanized iron sheet roofing
The base material of the corrugated galvanized iron sheet roofing is first made of high-quality steel. After being processed by cold rolling or hot rolling, it obtains precise size and smooth surface. Then, it is processed into profiles of various shapes, such as corrugated sheet, flanged sheet, channel steel, etc. through a special corrugated processing technology. These profiles are widely used in construction, manufacturing, transportation and other fields, and are favored for their high strength and durability.
In order to enhance the corrosion resistance of corrugated galvanized steel sheet, galvanizing is also required. Galvanizing is the process of covering the surface of the steel sheet with a layer of zinc. Through hot-dip galvanizing or electro-galvanizing process, zinc is closely combined with the surface of the steel sheet. This layer of zinc can form a protective film in the atmosphere, preventing the steel from directly contacting the external environment, thereby playing an anti-corrosion role. Galvanizing can also give the steel sheet good welding performance and strength, extending its service life.
