Application Scenario of Galvanized Steel Coil 

 

1.Construction field

 

Structural parts and cladding: galvanized steel plate is used for roofs, walls, ceilings, box beams, bridges and soundproof walls, providing weather resistance and corrosion protection.

 

Light steel structure: suitable for the manufacture of low-rise buildings, sandwich panels, metal roof tiles and PVC door and window reinforcement profiles.

 

Pipeline system: galvanized steel sheet is used for anti-corrosion lining of culvert pipes and heating facility pipes.

Galvanized Steel Coil 

2.Automobile manufacturing

Body parts: including structural parts such as automobile roofs, shells, compartment panels and chassis.

Functional components: hot dipped galvanized coil is widely used for corrosion-resistant parts such as mufflers, exhaust pipes, fuel tanks, etc.

3.Home appliance industry

Housing and structural parts: the housing and internal support parts of household appliances such as refrigerators, washing machines, and air conditioners.

Precision components: hot dip galvanized steel coil after surface treatment (such as phosphating process) are used in precision processing scenarios such as door panels and control panels.

 

4.Machinery and electrical equipment

 

Instrument housing: manufacturing of electrical cabinets, metering devices and industrial equipment housings, with both protection and formability.

 

Transformer components: hot dip Gi steel coil is used in conductors and transformer components of power equipment.

 

5.Transportation and others

 

Ships and rail transportation: shipbuilding car panels, public transportation body cladding.

 

Agricultural machinery: agricultural machinery parts used in humid environments (such as harvester housings).

 

Furniture and daily necessities: lampshades, shelves, bathtubs and other household products and metal containers.
