Color Coated Steel Coil

       Color-coated steel plate is a new type of strip steel pre-coating product that has developed rapidly in the world in the past three decades. It is refined by chemical pretreatment, primary coating, fine coating and other processes on a high-speed continuous unit. The coating quality is far more uniform, stable and ideal than the quality of single-piece spraying or brushing on the formed metal surface;

  The color-coated steel plate has excellent decoration, formability, corrosion resistance, strong coating adhesion, and can keep the color novel for a long time. Because the color coated steel plate can achieve good economic benefits such as replacing wood with steel, efficient construction, energy saving, and pollution prevention, it has become an ideal material for manufacturing building boards today.


The company's color coating products are mainly divided into two categories: ordinary color coating and reticulated color coating. Various colours are available according to the RAL colour card. Colors can also be configured according to customer samples. Reticulated products can also be subdivided into large reticulated and small reticulated. The specific requirements can be communicated in depth with our business according to the customer's situation, so that the customer can achieve the most satisfactory results.

Detailed explanation of color steel plate

1. Basic Features

1. Light weight: 10-14 kg/square meter, equivalent to 1/30 of the brick wall.

2. Thermal insulation: thermal conductivity of core material: λ<=0.041w/mk.

3. High strength: it can be used as a ceiling enclosure structure plate to bear load, resist bending and compression; general houses do not need beams and columns.

4. Bright color: no surface decoration is required, and the maintenance period of the color galvanized steel anti-corrosion layer is 10-15 years.

5. Flexible and fast installation: the construction period can be shortened by more than 40%.

6. Oxygen Index: (OI) 32.0 (Provincial Fire Product Quality Inspection Station).

2. Main types

The substrates of color steel plates are cold-rolled substrates, hot-dip galvanized substrates and electro-galvanized substrates. Coating types can be divided into polyester, silicon modified polyester, polyvinylidene fluoride and plastisol. The surface state of color steel plate can be divided into coated plate, embossed plate and printed plate. Color steel plate is widely used in construction household appliances and transportation industries. For the construction industry, it is mainly used in steel structure workshops, airports, warehouses and refrigeration industries. The roof walls and doors of commercial buildings, etc., civil buildings use less color steel plates.

Different from plastic steel

The difference between it and plastic steel is that the composition of the material is different, and the magnet can be sucked.

Strictly speaking, plastic steel and color steel cannot be well differentiated in terms of metal properties and surface treatment, because they are similar, so the market is mainly differentiated in terms of profile structure.

      magnet test

Because it is an ordinary carbon steel material, the magnet can suck. In addition, it should be added that stainless steel is the product of adding chromium element (greater than or equal to 13%) on the basis of low-carbon steel, so magnets cannot absorb it.

3. Development Trend

First, the use of high-quality substrates has higher and higher requirements for the surface, shape and dimensional accuracy of the substrates. Outdoors such as small spangle flat hot-dip galvanized steel coils and non-spangle flat hot-dip galvanized steel coils are released in time. The rise of zinc alloy hot-dip coil; indoor use such as electro-galvanized steel coil, film cold-rolled sheet and aluminum coil.

Second, to improve the pretreatment process and pretreatment solution, the number of equipment is small and the cost is low to become the mainstream process, and the stability, corrosion resistance and environmental performance of the pretreatment solution are continuously improved.

Third, focus on the development of new coatings, improve general polyester, polyvinylidene fluoride (PVDF) and plastisol to obtain super color reproducibility, anti-ultraviolet, anti-sulfur dioxide, and improve corrosion resistance; Thermal and other functional coatings.

Fourth, the unit equipment is more complete. Such as the use of new welding machines, new roller coaters, perfect curing furnaces, and advanced automation instruments.

Fifth, because cold embossing is lower in cost than hot embossing, and has the characteristics of beauty, three-dimensionality, and high strength, cold embossing production technology has become a development trend.

Sixth, pay attention to the diversification, functionalization and high-grade of products, such as deep-drawing color-coated boards, "yuzu skin" color-coated boards, anti-static color-coated boards, pollution-resistant color-coated boards, and high heat-absorbing color-coated boards Wait.

4. Features and performance

The color steel plate coating is a product made of cold-rolled steel plate and galvanized steel plate, after chemical treatment on the surface, coating (roll coating) or composite organic film (PVC film, etc.), and then baking and curing. Some people also call this product "pre-rolled color steel plate" and "plastic color steel plate". Color plate products are produced in coils by manufacturers on a continuous production line, so they are also called color-coated steel coils. Color steel plate not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials. Color steel plate is an emerging material respected in the world today. With the advancement of science and technology, the enhancement of environmental awareness, and the improvement of people's living standards, color steel prefab houses are increasingly showing strong vitality and broad market prospects. and other industries.

The color steel prefab house has the advantages of light weight, high strength, thermal insulation, beautiful and durable, etc. It is a high-level building and installation that integrates construction and decoration. The color steel prefab house is clean in construction and is widely used in large-span workshops, warehouses, office buildings, villas, roof additions, air purification rooms, cold storage, shops, kiosks and temporary housing. Light color steel sandwich panels with a weight of less than 14KG per square meter can fully reduce the structural load and reduce the structural cost of the prefab.

    Easy to install

The characteristics of the color steel prefab house's light weight, spliced installation and optional cutting determine the ease of installation of the prefab house, which can greatly improve the efficiency and save the construction period. The surface material and thermal insulation material of the fireproof color steel plate sandwich panel are non-combustible materials, which can fully meet the fire protection requirements of the prefab house.


Various studies have shown that it has been widely used in foreign countries for more than 40 years and confirmed that the shelf life of color steel plates treated with special coatings is 10-15 years. After that, anti-corrosion coatings are sprayed every 10 years, and the life of prefabricated panels can reach more than 35 years.


The clear lines of the profiled color steel plate are as many as dozens of colors, which can meet the needs of any style of prefab buildings and achieve satisfactory results.

Five, constitute the application

1. The substrates of color steel plates can be divided into cold-rolled substrates, hot-dip galvanized substrates, and electro-galvanized substrates.

2. The coating types of color steel plates can be divided into: polyester, silicon modified polyester, polyvinylidene fluoride, plastisol.

3. The color of the color steel plate can be divided into many types according to the user's requirements, such as orange, milk yellow, deep sky blue, sea blue, crimson, brick red, ivory, porcelain blue, etc.

4. The surface state of color steel plate can be divided into coated plate, embossed plate and printed plate.

5. The market uses of color-coated steel sheets are mainly divided into three parts: construction, home appliances and transportation. Among them, the construction industry accounts for the largest proportion, followed by the home appliance industry, and the transportation industry only accounts for a small part.

Color steel sheets for construction generally use hot-dip galvanized steel sheets and hot-dip galvanized steel sheets as substrates, and are mainly processed into corrugated sheets or composite sandwich panels with polyurethane, which are used to build steel structure workshops, airports, warehouses, freezers and other industries and businesses. Roofs, walls, doors of buildings.

Home appliance color plates are generally based on electro-galvanized and cold plates, and are used in the production of refrigerators and large air-conditioning systems, freezers, bread machines, and furniture.
