Prepainted Galvanized Steel Coil

Prepainted steel coils use hot-dip galvanized sheets, hot-dip galvalume sheets, electro-galvanized sheets, etc. as substrates. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are coated on the surface, and then A product that is baked and solidified. Colored steel coils are named after being coated with organic coatings of various colors, referred to as color-coated coils.

Prepainted steel coils are lightweight, beautiful, and have good anti-corrosion properties, and can be processed directly. The colors are generally gray-white, sea blue, and brick red. They are mainly used in advertising, construction, home appliances, electrical appliances, furniture, and transportation industries.

Advantages

Light weight

Because the color steel plate itself is light weight, convenient for transportation,and can save construction time.

Environmental protection and saving

The activity room made of color steel plate can be reused, which is environmentally friendly and saves money, without pollution and noise.

High strength

Because it is a steel structure, with strong bearing capacity, compression and bending resistance.

Smooth and easy to clean

The colorful galvanized steel coil is not rough in appearance and has a long anti-corrosion period, suitable for repeated use.

Characteristics of prepainted color-coated coil substrate

Electro-galvanized substrate: The coating is thinner and its corrosion resistance is not as good as that of hot-dip galvanized substrate;

Hot-dip galvanized substrate: a thin steel plate is immersed in a molten zinc bath to adhere a layer of zinc to the surface. This galvanized plate has good paint adhesion and weldability.

Color-coated steel is produced using galvanized coils of Z100, Z140, Z200, Z225, Z275, Z350 quality and with other metallic coatings in line with EN 10346/ DSTU EN 10346 that are made of such steels as:

  • DX51D, DX52D, DX53D, DX54D, DX56D, DX57D for profiling and drawing
  • HX160YD, HX180YD, HX180BD, HX220YD, HX300LAD, etc, for cold- forming
  • S220GD and S250GD for construction and framing
  • Multi-phase steels HDT450F, HCT490X, HDT590X, HCT780X, HCT980X, HCT780T, HDT580X, etc, for cold-forming

Key Types of Colour-Coating

Polyester (PE)

Namely (PE), Good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance, low cost.

Silicon modified polyester (SMP)

Namely (SMP), the hardness, abrasion resistance and heat resistance of the coating film are good, as well as good external durability and chalking resistance, gloss retention, average flexibility, and medium cost.

High durability polyester (HDP)

Namely (HDP), excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good paint film adhesion, rich colors, and excellent cost performance.

Polyvinylidene fluoride (PVDF)

Namely (PVDF), excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good formability, dirt resistance, limited colors, and high cost.

Basic standard specifications for continuously organic coated (coil-coated) flat steel products are set forth in BS EN 10169:2010+A1:2012. Basic colours are selected according to the RAL Classic standard.
