Galvanized corrugated roofing sheets mainly include color coated roofing sheet, galvanized roofing sheet and other metal sheet. These sheets are rolled cold bending into various wave patterns, suitable for industrial and civil buildings, warehouses, special buildings, long-span steel structure of the roof, wall and interior and exterior wall decoration. Galvanized corrugated roofing sheet has the characteristics of light weight, high strength, rich color, convenient and quick construction, earthquake resistance, fire prevention, rain proof, long life, maintenance-free, etc., so it is widely used.

Galvanized corrugated roofing sheet has a variety of specifications, including length, width and thickness and other aspects of choice, zinc coating z30-600g/m2.

In terms of length, the common length has a variety of options such as 1200mm, 2440mm, 3050mm, 3660mm and 4270mm, and can also be customized according to user’s requirements.

In terms of width, the commonly used width is 900mm, 1000mm, 1200mm and other specifications, and can also be adjusted according to actual needs.

In terms of thickness, the common thickness is 0.3mm, 0.4mm, 0.5mm, 0.6mm, etc., which can also be selected according to the actual situation of the building.

Galvanized corrugated roofing sheet is widely used in construction, vehicles, household appliances, daily necessities and other industries, because its galvanized treatment can effectively prevent steel corrosion and extend the service life. In practical applications, appropriate specifications and sizes can be selected according to specific needs to meet different architectural and design requirements.

Product Features: Easier & quicker installation, anti-seismic, anti-rain, longer-service life, easier maintenance.

Aluzinc Galvalume Steel Coil/Galvalume Steel Coil Sheet/Galvalume Steel Strip/Galvalume Steel Roll/Aluzinc Steel Coil/GL Steel Coil/Zincalume Steel/Aluminum-zinc Alloy Coated Steel/Aluminized Zinc Steel/Aluzinc Steel/SGLC/Galvalume Metal

Galvalume steel is carbon steel coated with an alloy that combines the impervious properties of aluminum with the malleability and galvanic protection of zinc. The alloy coating gives galvalume steel coil and sheets a smooth, plain finish.The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600 ~C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy. The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of galvalume steel sheet is up to 25a, and its heat resistance is good. It can be used in high temperature environment at 315 C. The adhesion between coating and paint film is good, and it has good processing performance. It can be punched, sheared and welded. The surface conductivity is very good.

Characteristics of Galvalume Steel:

Machinability
It can satisfy the processing requirements of rolling, coiling and others processes alike.

Thermal resistance
Common HDG steel plate normally works under 230℃, and has its color changed at 250℃, however, Galvalume steel plate cansustain the environment at 315℃ for long time.

High reflectivity
Reflection ability of heat and light is twice as much as those of hot-dip zinc steel sheet, and its reflectivity is more than 0.70, exceeding 0.65, which is an ideal construction materials of saving energy.

Resistance to corrosion
Aluzinc coated steel sheet has better performance in corrosion resistance than GI sheet of the same thickness and its service life is 2-6 times longer than general GI sheet.
