There are many materials and classifications of hot-dip galvanized coil, including ordinary plate and deep drawing plate, patterned plate and non patterned plate (environmental protection and non environmental protection), the height of zinc layer, and the commonly used steel grades are SGCC, dc51d + Z (52d.53d…), dx51d + Z (52d.53d…), st02z (03.04…), etc. Production process flow: uncoiling, welding, pretreatment, inlet looper, heating furnace annealing, zinc pot, air knife, water quenching, finishing, tension straightening and winding. There is no hot rolling and cold rolling between patterned galvanized sheet and non patterned galvanized sheet. After cold rolling, the cold sheet is coated with zinc to become patterned and non patterned.

Production standard

1. Standard size of galvanized coil: the steel plate is flat and rectangular, which can be directly rolled or cut from the wide steel strip. Steel plates are divided into thin plates according to thickness. The steel plate is divided into hot-rolled steel plate and cold-rolled steel plate according to the rolling point. The width of the sheet is 500-1500 mm; The thickness and width are 600-3000 mm. The thin plate is divided into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron thin plate. According to professional use, there are oil barrel plate, enamel plate, bulletproof plate, etc. The surface coating includes galvanized plate, tinplate, tinplate, plastic composite steel plate, etc.
2. Size and specification of galvanized coil: size and specification of galvanized coil, thickness of galvanized sheet.

3. Appearance of galvanized coil: (1) surface state: galvanized sheet has different surface states due to different treatment methods in the coating process, such as ordinary zinc flower, fine zinc flower, flat zinc flower, non zinc flower and phosphated surface.

When ordering, some specific defects shall be listed in the contract.

4. Standard value of galvanizing amount: galvanizing amount is a common and effective method to represent the thickness of zinc layer of galvanized coil. Galvanizing unit is g / m2. G
