Detailed explanation of color-coated steel plate types, colors and applications

Characteristics of Color-Coated Steel Sheets

Color-coated steel sheets are produced by spraying paint onto hot-dip galvanized or galvalume steel sheets, followed by multiple spray painting and baking processes. The base material of color-coated steel sheets can be cold-rolled, hot-dip galvanized, or electrogalvanized steel.

Colors of Color-Coated Steel Sheets

The colors of color-coated steel sheets can be customized according to user needs. Common colors include orange, pale yellow, dark sky blue, sea blue, brick red, ivory, and sky blue. The surface states of color-coated steel sheets can be divided into coated sheets, embossed sheets, and printed sheets.

Application Fields of Color-Coated Steel Sheets

The market applications of color-coated steel sheets are mainly divided into three parts: construction, home appliances, and transportation. Among them, the application proportion in the construction field is the largest, followed by the home appliance field, and the application in the transportation field is relatively small.

Color-Coated Steel Sheets for Construction

Color-coated steel sheets for construction are generally made of hot-dip galvanized steel sheets and hot-dip galvalume steel sheets. They are mainly processed into corrugated sheets or polyurethane composite sandwich panels and used for the roofs, walls, and doors of steel structure factories, airports, warehouses, cold storage, and other industrial and commercial buildings.

Color-Coated Steel Sheets for Home Appliances

Color-coated steel sheets for home appliances generally use electrogalvanized and cold-rolled steel sheets as base materials. They are mainly used in the production of refrigerators, large air conditioning systems, freezers, bread makers, furniture, etc.

Color-Coated Steel Sheets for Transportation

Color-coated steel sheets for transportation generally use galvanized and cold-rolled steel sheets as the base materials. They are mainly used in oil pans, automotive interior parts, etc. The specifications of color-coated steel sheets are generally between 0.25 mm and 0.7 mm, and the price decreases as the thickness increases. A representative specification for rolled color-coated steel sheets is 0.47 mm.
