Galvanized Coil with Spangle

Galvanized sheet steel products are mainly used in construction, light industry, automobile, agriculture, livestock and fishery and commercial industries. Among them, the construction industry is mainly used to manufacture corrosion-resistant industrial and civil building roof panels, roof grills, etc.; light industry with its manufacturing appliances shell, civil chimneys, kitchen utensils, etc., the automotive industry is mainly used for the manufacture of corrosion-resistant parts of the car board, etc.; agriculture, animal husbandry and fisheries are mainly used for food storage and transportation, meat and aquatic products, frozen processing appliances, etc.; business is mainly used for the storage and transportation of materials, packaging appliances, etc..

1、Steel plate for Car 

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.

2、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)

3、Home appliance office sheet

Including air conditioners, washing machines, refrigerators, photocopiers, etc., household galvanized sheets are mainly used for general forming applications and stamping.

4、Basic raw material

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.

Galvanized Steel Coil Supplier

We can manufacture and sell galvanized steel coils with a width of 600-1250mm and a coating weight of 20-300g/m3.  We have sufficient galvanized steel coil stock for fast delivery.

Surface Structure

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.

Hot Dipped Galvanized Steel Coil Production

The manufacturing of galvanized steel coil & sheet with good weather resistance, primarily used in construction.

Galvanized steel coils production process：

1.Uncoiler

2.Welder

3.Entry Looper

4.Pre-treatment

5.Annealing Furnace

6.Zinc Pot

7.Cooling Tower

8.Water Quench Tank

9.Skin Pass

10.Tension Leveler

11.Passivation Coater

12.Exit Looper

13.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.
