1. The main use: Hot-dip galvanized sheets are mainly used in automobiles, home appliances, construction, machinery, electronics, light industry and other industries.
  2. Steel plant galvanizing classification

There are two methods of galvanizing products shipped from steel plants: electro-galvanizing and hot-dip galvanizing.

These two categories are further subdivided. Electro-galvanizing is divided into three categories: single-sided, double-sided and differential thickness coating in terms of zinc layer thickness;

Hot-dip galvanizing does not have single-sided and differential thickness coatings, but hot-dip galvanizing is divided into galvanized and galvanized iron alloy, while electroplating does not have zinc-iron alloy.

In terms of coating types, electroplated coatings extend to electro-zinc plating, electro-zinc-nickel plating, electro-tin plating, and electro-chromium plating;

Hot-dip galvanizing has more extensions, including hot-dip galvanizing, zinc-iron, aluminum-zinc, zinc-aluminum, and zinc-aluminum-magnesium.

  1. Annealing method:The annealing methods of conventional cold-rolled coated products are continuous annealing and cover annealing.
  2. Commonly used steel types: Product categories: General commodity coil (CQ), deep-drawn hot-dip galvanized sheet (DQ), ultra-deep-drawn hot-dip galvanized sheet (DDQ-EDDQ/SEDDQ), structural galvanized sheet (HSLA), bake-hardened hot-dip galvanized sheet Plate (BH), dual phase steel (DP), TRIP steel (transformation induced plasticity steel), etc., complex phase steel (CP), etc.
  3. Zinc flower classification:Zinc flowers are generally divided into large zinc flowers, small zinc flowers, and no zinc flowers.
