High Quality Prepainted Galvalume Steel Coils Aluzinc Color Coated Steel in Coil

We rely on technology to form cost advantage and lay a good profit foundation in the development and design stage of the Galvanized Currugated Steel Sheet Plate, PPGI Color Coated Corrugated Steel Roofing Sheet, Prepainted Corrugated Steel Roofing Sheets. With the continuous use of new products and technologies, the continuous improvement of customer expectations, and the innovation of competitors, the competition faced by enterprises is becoming increasingly fierce. With the development of the company, our demand for talents is gradually increasing, especially the talents with high professional degree and strong comprehensive ability are favored. Our company has formed a good situation in which technological innovation and talent training promote each other and develop together.

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.

We can create additional value in mutual interest with our customers and provide sound solutions to them, making us become a preferred manufacturer of High Quality Prepainted Galvalume Steel Coils Aluzinc Color Coated Steel in Coil. The company has a professional training team that regularly conducts professional training for construction personnel. We take the company mission as the center, take the company vision as the goal, and constantly improve our comprehensive strength.
