We believe in long expression and trusted relationship for Cold Rolled Pre-painted Galvalume Steel Coil, Galvanised Roofing Corrugated Iron Sheets, Color PPGI Corrugated Galvanised Roof Sheets. We never stop asking ourselves how we can make the customer experience better every day, and we will never stop the pace of innovation. Behind the sonorous and brilliant development, our excellent corporate culture, which has a long history and moistens the society, has led us all the way.

GL/GC sheet have excellent corrosion resistance, print-ability and workability. The De-greasing Section helps the removal of oil and dirt by a cascaded process of hot alkaline de-greasing, cold rising, hot rising and hot air drying. Then annealing is done in an electrically heated horizontal furnace operated under a protective atmosphere with a calibrated ratio of nitrogen and hydrogen generated in a state–of–the–art automated Protective Gas Plant using ammonia and air as primary raw materials.

Immersing it in a zinc bath maintained at 460 degree centigrade carries out hot dip galvanizing of the strip. The chemistry of the bath is carefully controlled to ensure proper adhesion and formability of the applied zinc together with bright blemish free uniform spangles.The galvanized coils are chromated to improve its resistance to white rust. The chromating parameters are continually monitored and sheets are regularly tested through salt-spray tests to ensure the performance of this process.
We can also provide galvanized plain and corrugated sheets with required length. Galvanized corrugated sheet can be produced with closed tolerance of standard depth, pitch and width.

Corrugated metal starts with carbon steel sheet which is then pressed into three-dimensional patterns, called corrugations, using a series of rollers in a cold roll forming process. Different roller die arrangements produce different types of corrugation,including waves, squares and angles. Cold rolling allows a thicker and stronger product that also presents a better appearance than hot-formed steel. Finished sheet is then sheared off to the desired length.

Our company has advanced equipment and testing means, Color Coated Iron Roof Corrugated Steel Sheet Tiles are sold all over the country. Our company ensures sufficient supply of goods, with a huge marketing network, can provide you with products in time. Our business is promoted in cooperation because we believe that win-win is the most stable, most efficient and happiest state of cooperation.
