Pre painted Galvanized Steel Coils Structure

Prepainted steel coil coatings can be divided into three categories: primer, topcoat, and backcoat. Common ones are 2/2 and 2/1 coating structures.

The back side of the 2/1 can be coated with a layer of primer or only a layer of backcoat. It is mainly used for sandwich panels, which require the coating to have good bonding and foaming properties. The 2/2 uses a two-coat system of primer and backcoat, and is used as a single steel sheet.

Top Finish Coating (PE/HDP/PVDF, etc.), When the thickness is above 20um, it can effectively prevent the damage of ultraviolet rays and harsh environments to the coating.

The main uses of pre-painted galvanized steel coils are home appliances and construction.

Home appliance uses are mainly side door panels for refrigerators, and shells for air conditioners, freezers, and washing machines. The construction field is more widely used than home appliances.

PPGI coil for construction is used for roofing, guttering, sandwich panels, industrial building facades, cold storage panels, and rolling doors. Our steel products are mainly applies in some professions, such as constructions. For the constructions, it mainly used as roofs of some industrial, residential construction to prevent from corrosion. For the light industry, it used to produce outer cover of electrical appliance, chimney, kitchen utensil and corrosion-proved parts of automobiles. And it is also used as storage and transport in farming, animal husbandry, fishery area.
