Galvanized Sheet coil 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.
Galvanized Steel Coil Uses
Galvanized steel coil has a wide range of applications, and its advantage is that it has a long anti-corrosion period. It is mainly used for home appliances, office panels, roof sheets, automotive panels, construction and substrate of prepainted steel coils.
Car board
The use of automotive plates must first be stamped and formed, and the steel plate is stamped into the required shape and size of the part.
Then spot welding, as an important welding method for thin plate connection, has a wide range of applications in the manufacturing industry, especially in the automotive industry.
Galvanized roof sheet
The performance requirements of galvanized roof panels mainly include the mechanical properties of the material (tensile strength, yield strength, elongation), coating performance (coating type, coating thickness and coating adhesion)
Home appliance office board
Including air conditioners, washing machines, refrigerators, photocopiers, etc., household galvanized sheets are mainly used for general forming applications and stamping.
Substrate
Another use of galvanized steel coils is to be used as the substrate of prepainted steel coils. prepainted steel coils have polyethylene coatings than galvanized coils and are more durable.
Standard Specification Of Galvanized steel coil
American ASTM A653 Standard Galvanized Steel Coil
Commercial Steel (CS Types A, B, and C)
Commercial Steel is a low-carbon cold-formed steel, such as galvanized steel roof forming
Forming Steel (FS Types A and B)
Requires higher drawability than Commercial Steel, such as for lamp cover forming
Deep Drawing Steel (DDS)
Extra Deep Drawing Steel (EDDS)
Structural Steel (SS) – (33,37,40,50,80)
High Strength Low Alloy Steel (HSLAS)
European EN 10346 Standard Galvanized Steel Coil
Low carbon steel for cold forming (DX51D – DX54D)
DX51D is equivalent to Commercial Steel, curved and profiled
DX52D is equivalent to Forming Steel
DX53D is equivalent to Deep Drawing Steel
DX54D is equivalent to Extra Deep Drawing Steel
Structural Steels (S220GD – S350GD)
S220GD,S250GD,S280GD,S320GD,S350GD
Use structural steel for high load-bearing capacity, with a yield strength of 220-350
Recoiler
The production and processing of galvanized steel coils can be divided into three steps: first, the entire coil is pickled to remove rust and dirt, so that the surface of the galvanized steel strip can achieve a bright and clean effect; after pickling, pass ammonium chloride or zinc chloride It is cleaned in an aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the hot-dip plating tank for the galvanizing process; after the galvanizing process is completed, it can be put into storage and packaged.
Surface Treatment Of Galvanized Steel Coil
Chromate treatment of galvanized steel coils is also called passivation treatment. Through passivation treatment, the surface structure and gloss of the galvanized layer can be improved, the corrosion resistance and service life of the galvanized layer can be improved, and the bonding force of the coating and the base metal can be improved.
The purpose of oiling galvanized steel coils is a protective layer is formed on the surface of the steel coil to prevent the surface from rusting.
