Color steel corrugated plate color steel roof bottom plate

Color steel plate refers to color coated steel plate, which is a steel plate with organic coating. Color steel plate is divided into veneer panel, color steel composite board, floor bearing board, etc. It is widely used for the walls and roofs of large public buildings, public factories, prefabricated houses and integrated houses.

Basic features:

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

2. Heat preservation and insulation: core thermal conductivity: λ< =0.041 w/mk

3. High strength: can be used as the load-bearing panel of the ceiling enclosure structure, bending and compressive resistance. Generally, beams and columns are not used in houses.

4. Bright color: no need for surface decoration, the preservation period of the anti-corrosion layer of color galvanized steel plate can reach 10-15 years.

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

6. Oxygen index: (OI) 32.0 (Provincial fire product quality testing station).

Main types: The base material of color steel plate is cold-rolled base material, hot-dip galvanized base material and electric galvanized base material. The types of coatings can be divided into polyester type, silicon modified polyester type, polyvinylidene fluoride type and plasticizer type. The surface state of color steel plate can be divided into coating plate, embossing plate and printing plate. Color steel plates are widely used in construction, household appliances and transportation industries. For the construction industry, it is mainly used in steel structure plants, airports, warehouses and refrigeration industries. For the roofs, walls and doors of commercial buildings, color steel plates are rarely used in civil buildings. The difference between it and plastic steel is that the composition of the material is different, and the magnet can attract. Strictly speaking, plastic steel and colored steel cannot be well distinguished in terms of metal properties and surface treatment because they are very similar. Therefore, the differentiation of the market is mainly manifested in the profile structure. Magnet test: Because it is made of ordinary carbon steel, the magnet can attract iron. In addition, I would like to add that stainless steel is the product of adding chromium (greater than or equal to 13%) to mild steel, so magnets cannot attract it.

The development trend.

First. the use of high-quality substrate, the surface of the substrate, plate shape and dimensional accuracy requirements are getting higher and higher. For outdoor use, such as flat hot galvanized steel coil with small kinks and no twisting hot galvanized steel coil is available in time. The rise of zinc alloy hot dip plating coil. Indoor use, such as electrogalvanized steel coils, film coated cold rolled sheets and aluminum coils.

Secondly. improving the pretreatment process and pretreatment liquid, reducing the number of equipment and reducing the cost has become the mainstream process, and constantly improve the stability, corrosion resistance and ecological environmental protection performance of the pretreatment liquid.

Third. pay attention to the development of new coatings, improve ordinary polyester, polyvinylidene fluoride (PVDF) and plastisol, obtain supercolor reproducibility, ultraviolet resistance, sulfur dioxide resistance, and improve corrosion resistance. Develop functional coatings that are resistant to pollution and heat absorption.

Fourth. the unit is fully equipped. Such as the use of new welding machine, new roller coating machine, perfect curing furnace, as well as advanced automatic instruments.

Fifth. because the cost of cold-pressed flowers is lower than that of hot-pressed flowers, and it has beautiful, three-dimensional effect and high strength characteristics, the production technology of cold-pressed flowers has become a development trend.

The sixth is to pay attention to the diversification, functionalization and high-grade of products, such as deep drawing color coating board, "grapefruit skin" color coating board, anti-static color coating board, anti-pollution color coating board, high-end heat-absorbing color coating board. The performance of the feature.

Color steel coating is cold-rolled steel plate, galvanized steel plate, coated (roll coating) or composite organic film (PVC film, etc.), after chemical surface treatment and then baking and curing products. There are also people who call this product "pre-roll coated steel plate" and "plastic colored steel plate". Color steel plate products are produced by manufacturers in rolls on continuous production lines, so it is also known as color coated steel plate rolls. Color steel plate not only has the high mechanical strength and easy molding properties of steel materials, but also has the good decorative properties and corrosion resistance of coating materials. Color steel plate is an emerging material respected in today's world. With the progress of science and technology, the enhancement of environmental awareness, and the improvement of people's living standards, the color steel plate activity room is increasingly showing a strong vitality and broad market prospects. Favored by construction, home appliances, mechanical and electrical, transportation, interior decoration, office equipment and other industries. And other industries.

The color plate activity room has the advantages of light weight, high strength, heat preservation, beautiful and durable, and is a kind of fast building that integrates construction and decoration. Color steel prefabricated room construction clean, widely used in large-span workshop, warehouse, office buildings, villas, roof, air purification room, cold storage, shops, pavilions, temporary housing and so on. The square meter weight of light color steel plate sandwich board is less than 14KG, which can fully reduce the structural load and reduce the structural cost of mobile houses.

The color steel movable board room is light in weight, can be spliced, and can be cut at will, which determines the difficulty of the installation of the movable board room, which can greatly improve efficiency and save time. The surface layer material and insulation material of the fireproof color steel sandwich board are non-combustible materials, which can fully meet the requirements of the fire protection code of prefabricated houses.

Various studies have shown that after more than 40 years of extensive use abroad, the shelf life of specially coated color steel plates is 10-15 years. After that, the anti-corrosion coating is sprayed once every 10 years, and the life of the mobile room board can reach more than 35 years.

The clear lines of the color steel plate of the United States can meet the needs of any style of prefabricated buildings and achieve satisfactory results.

1. The substrate of color steel plate can be divided into cold-rolled substrate, hot-dip galvanized substrate and electric galvanized substrate.

2. The coating type of color steel plate can be divided into: polyester, silicon modified polyester, polyvinylidene fluoride, and plasticizing sol.

3. The color of color steel plate can be divided into various types according to the requirements of users, such as orange, milky yellow, deep sky blue, navy blue, crimson, brick red, ivory, porcelain blue and so on.

4. The surface condition of color steel plate can be divided into coating plate, embossing plate and printing plate.

5. The market use of color coated steel plate is mainly divided into three parts: construction, home appliances and transportation. Among them, the construction sector accounts for the largest proportion, followed by the home appliance industry, and the transportation industry only accounts for a smaller part.

Color steel plates for construction generally use hot-dip galvanized steel plates and hot-dip galvanized alloy steel plates as substrate. We are mainly processed into corrugated cardboard or polyurethane composite sandwich board, which is used in the construction of steel structure factory buildings, airports, warehouses, freezers and other industrial and commercial buildings. Building roofs, walls, doors.

Home appliance color plate is generally galvanized and cold plate as the base material, which is used to make refrigerators and large air conditioning systems, freezers, toasters, furniture, etc.

In the transportation industry, electric galvanized and cold plate are generally used as substrates, mainly for oil pan, automotive interior parts and so on.
