The performance of hot rolled products is so good, such as high strength, good toughness, easy processing and good weldability molding, etc. Therefore, it is widely used in ships, cars, bridges, buildings, machinery, pressure vessels and other manufacturing industries.

In contrast, cold rolled coil is at room temperature directly into a certain thickness of the rolling roll with a rolling machine and rolled into the entire volume of the strip. Usually, it is used in in automobile manufacturing, machinery manufacturing, light industrial, civil and construction, etc.

In additon, there are many related products of steel coil, according to the different application, they all play a key role in production. For example, galvanized steel coil owns excellent corrosion resistance, paint, decoration and good formability, it is widely used in construction, household appliances, vehicles, container manufacturing, mechanical and electrical industry, to almost all areas related to basic necessities. In recent years, increasing demand for Galvanized steel coil, production increased quickly in the United States, Japan and other steel producing countries, galvanized steel coil occupys a high proportion.

Certainly, there are all kinds of steel coil, like galvalume coil, PPGI, PPGL, etc. because of different fucnitons or featrues, they can be used different areas and play an important role. http://www.chinazhongniu.com/_d272714220.htm
