Zincalume Corrugated Steel Roofing Sheet Gi Corrugated Zinc Roof Sheets Metal
Our corrugated metal products are available with a thickness from 0.11mm and 0.7mm,
roof sheets cut to any length up to 6m.
Corrugated Galvanized Steel Roofing
- The corrugated galvanized steel roofing is made of galvanized steel coil and processed by a roll forming machine.
- According to the difference of galvanizing, it is divided into big spangle and zero spangles. According to the production method, it can be divided into hot-dip galvanized steel, electro-galvanized steel, and alloy-galvanized steel.
- African customers mainly purchase 0.13*665 length, with zero spangles corrugated galvanized steel roofing.
- Among them, we mainly sell corrugated hot-dip galvanized steel sheets because the production of electro-galvanized steel sheets will pollute the environment.
- The logo can be customized on the surface of the corrugated galvanized steel sheet according to customer requirements.
The corrugated galvanized steel roofing has a double-sided coating weight of 20-275 g/m2 according to ASTM test. The most commonly used corrugated galvanized steel sheets for building applications are Z275 and Z450, and the galvanizing amount is 275 g/m2 (the minimum thickness of the single-sided coated of the steel sheet is 19 μm) and 450g/m2.
Corrugated galvanized steel is one of the strongest, most durable roofing materials, since it lasts longer, is more resistant to wind, and absorbs less heat than asphalt shingles.
Does galvanized roofing sheet rust?
So does galvanized steel rust? The answer is yes, but very slowly. In fact, slow enough that it's usually not a problem.
This is why galvanized steel has been in use for the last 2,000 years, and why it's probably going to be okay in your application

Product Applications
Corrugated Metal Panels are building materials made from sheets of hot dip galvanized steel which are cold rolled to produce the rippled pattern we see in them. The corrugations in the panels increase the bending strength of the sheets in the direction perpendicular to the corrugations. Corrugated Metal Panels are:
- Weather resistant
- Lightweight & tough
- Easily transported
See examples of customer installations using corrugated roofing sheets.
Our continuous galvanizing line can process steel strips of thickness from 0.1mm to 0.8mm and width up to 1200mm. It applies precisely controlled uniform protective layer of Zinc on steel surface with very strong adherence, This steel surface is further protected with a layer of Chromatic acid to ensure no surface rusting during transportation and storage.
regular used types:
1 galvanized roofing sheet have the most competitive price,
It is widely used for some simple buildings, such as temporary housing,
warehouse, chicken house etc, light weight, easy to install.
2 T type roofing sheet, it is widely used for various sandwich panel,
Industrial building, the most remarkable feature is fire proof,
have great sound insulation effect.
3 Galvalume roofing sheet have the perfect corrosion resistance,
It also has great properties of heat resistance, its heat reflection is double higher
than galvanized sheet, so it is excellent heat insulator.
