Cold Rolled Steel Sheet
Spangled galvanized steel sheet is the spangle obtained by the condensation of the zinc coating under normal conditions after galvanizing. It is mainly used in buildings and other places where there is little direct contact with the human body.
Galvanized steel sheets without spangles are mainly produced through a special production process to control the lead in the zinc pot to a certain level, or after the strip steel is out of the galvanized pot, it undergoes special treatment to control the spangles to less than a certain level. Mainly used in home appliance housing
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.
Hot-dip galvanized coils are divided into pure zinc coating and zinc-iron alloy coating according to the coating. Their common point is that the zinc content of the zinc solution in the zinc pot is the same. The difference is that the zinc-iron alloy adds an alloying process.
In the hot-dip galvanizing production line, the pre-treated steel strip is immersed in the molten zinc bath to obtain the coating. The zinc content in the molten zinc solution should not be less than 99%.
A zinciron alloy layer is formed on the entire coating through an alloying treatment process, and the iron content in the alloy coating is usually 8-15%. During the alloying process, the galvanized steel coil is heated to 550-560°C in an alloying furnace in 5-10 seconds, so as to convert all the pure zinc layer into iron-zinc alloy. Its weldability, coating performance, heat resistance, and corrosion resistance are better than ordinary galvanized sheets.
For example:
EN 10346 DX51D+Z is pure zinc;
EN 10346 DX51D+ZF is zinc-iron alloy coating.
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)
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
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.
