Corrugated Galvanized Steel Sheet is also called corrugated galvanized iron in west country. It takes galvanized steel as the basic material and it is formed by roll forming technology according to the different curvatures required by customers. Because our product has good anti-corrosion properties, and the corrugated shape is very suitable for the roof to facilitate the rapid flow of rainwater, so it iscommonly used for the roof of the movable board room or ordinary house.
1.It has faster construction, lower cost and beautiful appearance than ordinary tile roofs.
2.Compared to ordinary painted steel plates, the hot dipped galvanized technology 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.
3.It is easy and fast for installation, which greatly reduced your project cost and maintenance cost.
Our products 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.
Reasons for white rust on the Corrugated Galvanized sheet surface
Black spot and whiter rust on galvanized sheet surface 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 antirust oil on the corrugated sheet surface;Process in storage and portation
(3) the residual water on the strip surface;
(4) uncompletable drying of passivation
(5) wet or soaked in trans portation or storage.
(6) the storage time of the finished product is too long
(7)contacted or stored with other corrosive media such as acid and alkali.
During production, we successfully avoid the black spot and white rust on the corrugated galvanized steel sheet. In the process of storage and transportation of warehouses, we strictly follow the storage requirements of corrugated steel plates, and all the surfaces are made of anti-rust oil. At the same time, the temperature and humidity of the warehouse are all kept within the required range, avoiding contact with chemical corrosion products such as strong acid and alkali.
