Hot Dipped Galvanized Steel Coils and Sheet

Hot-dip galvanized sheet and coil are very similar in terms of properties and characteristics and are two forms of galvanized steel. Galvanized coils are widely used in the construction sector, while galvanized sheets are easier to process directly and are therefore used in the manufacture of household appliances and automobiles. You can choose the right type of galvanized steel for your application, or contact us, and we will make a recommendation based on your needs.

Advantages of HDG Steel

  1. Good corrosion resistance and plasticity.
  2. high strength and wear resistance.
  3. easy to process and use.

Uses of HDG Steel

  1. Outdoor: roof tiles, roof components, pipes, doors, windows, guardrails, etc.
  2. Indoor: indoor partition, wall decoration, house ceiling, etc.
  3. Home appliances: all kinds of home appliances shell.

Galvanized Steel Process

After selecting the required material, thickness, zinc coating, and surface finish, production can begin. Hot-dip galvanized steel is a straightforward process and its cost is the lowest among coated steels, including aluminum-zinc plated, color-coated, zinc-magnesium-aluminum, and other types of coated steels.

  1. Surface treatment: Commonly used steels are DX51D, SGCC, and other materials, through degreasing, pickling, etc. to remove surface impurities, ready.
  2. Hot-dip galvanizing: Prepare a zinc bath at a temperature of 500 degrees Celsius and immerse the steel in the bath to adjust the thickness of the zinc layer and the surface effect.
  3. Inspection and packaging: After galvanizing, the steel is cooled down and awaits inspection and packaging. (Depending on the application and cost, it can choose a coating or fingerprint-resistant treatment. )

Hot-dip Galvanizing and Electro-galvanizing

Surface: Hot dip galvanized steel can be supplied with zinc, regular spangle, or free spangle, galvanized steel is zero spangle.
Zinc thickness: Hot-dip galvanized steel has a thicker zinc coating.
Application: Hot-dip galvanized steel can be used outdoors in highly corrosive environments, while electro-galvanized steel is suitable for use indoors in general environments.
Cost: Hot-dip galvanized steel costs less.
Lifespan: Hot-dip galvanized steel generally has a longer lifespan than electro-galvanized steel, despite the different environments in which it is used.

Hot dip Galvanized Steel Price
