Galvanized is a term long used to describe steel sheets coated with zinc. Usually associated with the hot dipped process but the zinc coating can also be applied by electroplating. Our hot dipped galvanized sheets are produced to conform with ASTM A525. Electrogalvanized conforms to ASTM A591
The producing mills have accomplished many technological advancements in recent years in the manufacture of both hot dipped and electrogalvanized sheets. The end use should determine the type of coated product and surface condition required. Regardless of the coating weight, spangle size, method of manufacture or surface preparation required Following are descriptions of the grades and conditions of galvanized sheets used most often.
Colored Steel Roofing Sheet Application:
1. Excellent water resistance
After seaming treatment assembled on –site, it can endure any bad climate condition incase of the roof pitch is more than4%
2. Wide Application
Compose warm-keeping or non warm-keeping roofs cooperation with various warm –keeping materials and various bases. The length can be changed according to needs. to avoid longitudinal lap joint, thus to eliminate the possibility of water leakage. It has symmetrical shape with no fastening screw exposed, which is neat and beautiful and with excellent corrosion resistance, Adopt hook mechanism for fixing, firm and reliable and can bear the influences from changes of the thermal expansion. It has many advantages such as pretty appearance, convenient installation, smooth draining and economical building material.
Packing
Usually the packing of roof sheets is pallets, or according to the customers requirement.
The packing of roof sheets consists of anti-damp paper, cardboard, the cargoes will be strapped with steel strips, fixed with locks and edge protectors and guarantees the optimal condition of the delivered goods.

| Description | Galvanized steel is mild steel with a coating of zinc. The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel. Galvanized steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion. |
