Hot Dipped Galvanized Steel Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc's characteristics. Usually, hot-dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.

Commercial Steel is a low-carbon cold-formed steel, such as galvanized steel roof forming
Requires higher drawability than Commercial Steel, such as for lamp cover forming
Low carbon steel for cold forming (DX51D - DX54D)
Structural Steels (S220GD - S350GD)
S220GD,S250GD,S280GD,S320GD,S350GD
Use structural steel for high load-bearing capacity, with a yield strength of 220-350
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.
Shandong Lite Special Steel Co.,Ltd.was established in 2010. located in China, which is a steel coil manufacturer and supplier and factory. We have two galvanized coil production line, three-color coated coils, and one paint production line. Annual output of 800,000 tons of coated steel coils.
The main products are PPGI, PPGL, GI, GL. We have passed ISO 9001:2008 international quality system certification.
We have import & export rights since 2019 and have built long-term relationships with customers in Middle East, south Africa, Southeast Asia and South America.
Production Capacity: 250,000 tons/year
Specification: 0.2~1.2MM*800~1250MM
After surface degreasing, phosphating, and passivation treatment, multiple layers of organic coatings (such as modified resin (SMP), high weathering polyester (HDP), polyvinylidene fluoride (SPE) are coated on the surface by continuous roll coating. PVDF) and other coatings, which form a complete set of production equipment for new functional boards.
The production line consists of an unwinder, a sewing machine (welding machine), a stocker, a degreasing unit, a roll coater, a curing oven, a shearing machine, and the like. The machine consists of a roll machine.
Production Capacity: 300,000 tons/year
Specification: 0.12-0.7MM*800-1250MM
The galvanizing production line is a complete set of zinc alloy plating on the double-sided high-temperature hot-dip coating of the steel coil. The production line consists of an unwinder, a welder, a stocker, a degreasing cleaning unit, a continuous annealing furnace, a zinc pot, and an air knife.
It consists of equipment such as a finishing machine, tension leveler, oiling machine, shearing machine, and winder.
Mechanical performance
Mechanical properties can be defined as product properties that can be confirmed through tensile tests, such as yield strength, tensile strength, elongation, n value, r value, and so on. High elongation, high r value and high n value are conducive to stamping and forming
Coating performance
The coating performance of galvanized steel coil mainly refers to the corrosion resistance of the coating and the adhesion of the coating.
Corrosion resistance includes resistance to salt spray and humidity, and coating adhesion refers to the resistance of the product to cracking, peeling, and chalking of the coating during processing.
