Color Coated Building Material PPGI Corrugated Roofing Steel Sheet

After hard work and innovation, and years of professional accumulation, our company has developed into the largest High Strength Color Coated Steel Coils, PPGI Corrugated Steel Galvanised Roofing Sheets, Color Coated Corrugated Steel Roof Sheet manufacturer in China. The development and success of a business cannot be achieved without the support and efforts of technology, talent and customers. Through the implementation of standardized service management, high quality and low price products and the use of advanced marketing means, we have won the trust and support of our customers. We actively attract talents, learn from others' strengths, and uphold the concept of integrity, professionalism and win-win. We are grateful that the good policy of reform and opening up has brought us rare historical opportunities, it is the care and support of governments at all levels across the country that has given our company good development space.

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 continue to undertake new projects in the technical field, accumulate rich experience, and lay a technical foundation for the research and development of new series of Color Coated Building Material PPGI Corrugated Roofing Steel Sheet. Our company adheres to the core values of 'people-oriented, quality-oriented, new and strong', striving to build a world-class enterprise. We focus on our vision of being an industry-leading and respected world-class enterprise and combine it with the new internal and external situation we face, thus establishing our development philosophy of technology first.
