PPGI/PPGL/Prepainted Galvanized Steel/Prepainted Galvalume Steel/Color Coated Steel

Our Pre-painted Galvalume Steel Coil, Colored Galvanized Steel Coil, Gray Steel Roof Panels is very advantageous since we have introduced a large number of advanced production equipment, with imported high-quality raw materials, and the modern management model in line with international standards. Our company will continue to reform and innovate with a brand-new look and brand-new concept, and design and manufacture newer and better products to give back to users. According to the development trend and requirements of the industry, our company constantly pursues its own development and the development trend of the industry.

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 develop and use new materials in our PPGI/PPGL/Prepainted Galvanized Steel/Prepainted Galvalume Steel/Color Coated Steel to minimize the negative impact of our operations on the environment and to protect the ecological environment. As one of the important soft power of our company, quality ethics guides our business activities. Because it cannot be copied, it is an exclusive advantage for our company. Our company has a number of technical personnel specializing in new product development research and tracking guidance.
