Galvanized roof sheet manufacturer

Jiangsu Taigang Puxin Stainless Steel Co., Ltd. is a sophisticated manufacturer of steel products. It’s located in Wuxi, which is the biggest base of stainless steel products in China and is also near to Shanghai. We have been devoted in steel industry for nearly 15 years and developed many faithful clients in Europe, South America, Mid-East, India and etc. We have a wide range of stainless steel products. Other metal products are also available if customers require. The annual export volume is about 1000,000 tons. And we promised almost all inquiry will be dealed with within 3 hours. "Punctuality,Integrity, Humanization service” has always been the development principle that strictly adhered by our company and all stuff all the time.At present, we have five finishing rolling production lines and two hot rolling production lines . Further more advanced automatic width control system (AWC), automatic thickness control system (AGC), bending roll system, work roll channeling roll system and other effective measures are adopted to guarantee product quality.

What Is Galvanized roof sheet?

Galvanized roof sheet is a material consisting of a zinc layer applied to sheets of metal that go through a process called “Hot-Dipping”, in which the metal sheets go through a molten zinc bath. The zinc then bonds to the iron particles within the steel sheet and forms a protective layer on both sides.

Hot-Dipping is a process that helps protect metal materials such as steel sheets from corrosion caused by potential exposure to extreme environments. This is achieved through multiple processing types and it protects materials over a long time from degrading whilst maintaining their original properties unaltered.

While going through the molten zinc bath process it causes a reaction that bonds both metals’ external layers, thus creating a similar but highly resistant surface. The metal sheet then can be produced to a finished state because the zinc coating doesn’t flake or peel off during the manufacturing.

The finished metal then goes through a spinning process and can withstand corrosion with none added or secondary paint coating which makes it the most economical process for protecting steel.

Only using a magnet or a gauge can determine if the produced metal has a zinc coating, as a matter of fact sometimes then you see a gray coating it could mean the part has been painted, as a layer of paint would add thickness to it and the only real possible way to determine if it’s been “Hot-Dipped” can be achieved by running a laboratory test.

Chosen for over a century for being the most effective way of protecting metal from degrading, the “hot-dip” process is mostly chosen for its versatility and sustainability. It guarantees the materials’ durability over time and has a significant lower investment cost comparing to other materials.
