What is Color Coated Steel?

Color coated steel is steel made from hot-rolled steel, cold-rolled steel, galvanized steel, or galvalume steel as a substrate, which is coated with one or more layers of organic paint and then baked and cured. In general, galvanized and galvalume steels are used as substrates to increase the corrosion resistance of the steel. (Pre-painted galvanized steel and pre-painted galvalume steel are commonly used).

Cold rolled steel substrate: Cold rolled steel plate coated with paint, corrosion resistance is general, currently less used.
GI substrate: cold rolled steel or hot rolled steel surface through hot-dip galvanized or electro-galvanized zinc coating process, and then in the galvanized steel outside the coating, to increase the corrosion resistance.
GL substrate: The surface of cold rolled steel plate or hot rolled steel plate is plated with a galvalume alloy coating through the electroplating process, and then coated with paint on the outside, which has better corrosion resistance.

Surface State of Color Steel

Color coated steel has color-coated coil, color-coated sheet, colour-coated roofing, etc. Among them, according to different uses for aesthetics, non-slip, and decorative, color-coated sheets can also be divided into coated plates, embossed plates, and printed plates kinds of surfaces.

  1. Substrate preparation: Hot rolled sheet, cold rolled sheet or galvanized sheet is prepared according to the requirements, together with the raw material for coating and other auxiliary materials.
  2. Pre-treatment: The pre-treatment of the color-coated sheet includes two steps: first to clean the steel to remove impurities, and then to increase the surface treatment’s roughness to improve the coating’s adhesion.
  3. Coating: Choose the coating, determine the thickness, and then apply the coating to the surface of the steel plate by roller coating.
  4. Curing: The coated steel is first heated for initial curing, and then heated at high temperature for curing.
  5. Post-processing: The cooled color coated steel is tested for quality and then cut according to the need to complete the cutting.
  6. Packaging: Wanzhi Steel’s coils and plates are packaged in standard export packaging.

What are the Advantages of Colour Coated Steel?

Various surface effects: you can choose the color, pattern, material, and shape.
Strong corrosion resistance: The zinc, alloy, and color coating can effectively isolate air and moisture to protect the steel from rusting.
Processable: Steel is tough and the coating is tightly bonded to allow cutting, bending, stamping, and other processing.
Wide range of applications: Can be used in construction, household appliances, automotive, transport, and other fields.

Color Coated Steel Application Scenarios

The application of color coated steel is determined by the material of the substrate and the material of the coating, because of its lightweight, beauty, and corrosion resistance, so it is widely used in the construction, household appliances manufacturing and transportation industries.
