It is characterized by light weight, high strength, nice color, convenient and quick construction, fireproof, rain proof, long life and no maintenance.
The technology treatment of corrugated galvanized steel sheet is hot dipped galvanized technology, which greatly enhances the corrosion resistance of the steel plate, and makes the corrugated sheet more antioxidant than the ordinary galvanized steel sheet in the open and wet environment, and it greatly prolongs the service life of the corrugated galvanized steel sheet.

Reasons for white rust on the surface
Usually there are black spot and whiter rust on the corrugated galvanized steel sheet surface. It is considered as bad treatment and galvanization.
The black spot is formed by the further oxidation of white rust. The causes of white rust are as follows:
(1) the passivation is bad, and the thickness of passivation film is not enough or uneven.
(2) no oil on the surface;
(3) the residual water on the strip surface;
(4) uncompletable drying of passivation;
(5) wet or soaked in transportation or storage.
(6) the storage time of the finished product is too long;
(7)corrugated galvanized steel sheet is contacted or stored with other corrosive media such as acid and alkali.

Galvanized corrugated sheets are often and normally used in active roofing house and temporary roofing houses. Different corrugated shapes (wave shape, plain shape and trapezoidal shape) have solved the problems of roofing very well. It is the most popular roofing building materials on the market currently.
All we know the famous and popular movie named Beowulf 2.
Wolf Warrior 2 tells the story of a former Chinese Special Forces operative`s adventures journey to rescue compatriots and local friends in a war-torn region of Africa occupied by insurgents and mercenaries. The success of the film has surpassed the anticipations of all, including the production team. But in my opinion, the most startling scene is the buildings and roofs which use galvanized corrugated sheets. There are many slums in Slums, African prairies and African lion Gardens in Ethiopia, Somaliland, Sultan, Rwanda, Tanzania, Masai Mara, Kenya, South Luangwa National Park and Zambia.
Steel sheet roofing is already becoming the tendency of local buildings because of the economic, climate, environment and politics.
