Color steel pressed bottom plate color steel corrugated roof bottom plate

Color steel plate refers to color coated steel plate. Color coated steel is a type of steel plate with an 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 surface decoration is required, the anti-corrosion layer of colored galvanized steel plate will last 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. The application of colored steel plates such as roofs, walls and doors in civil buildings is becoming less and less. 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 color steel can not be well distinguished in terms of metal properties and surface treatment, because they are very similar. Therefore, the difference in the market is mainly reflected 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%) on the basis of mild steel, so the magnet cannot absorb.

The development trend.

First, the use of high-quality substrates, the surface, shape and dimensional accuracy of the substrate is increasingly required. For outdoor, such as small zinc flower plate hot galvanized steel coil, non-zinc flower plate hot galvanized steel coil, and the rising zinc alloy hot galvanized coil. Indoor use, such as electrogalvanized steel coils, film coated cold rolled sheets and aluminum coils.

The second is to improve the pretreatment process and pretreatment liquid, so that the number of equipment is small and the cost is low to become the mainstream process, and the stability, corrosion resistance and ecological environmental protection performance of the pretreatment liquid are constantly improved.

Third, pay attention to the development of new coatings, improve general polyester, polyvinylidene fluoride (PVDF) and plasticizer sol, to obtain super color reproduction, UV 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 cold embossing is cheaper than hot embossing and has the characteristics of beautiful appearance, good three-dimensional effect and high strength, cold embossing production technology 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 high mechanical strength of steel material, easy to form the performance, but also has a good decorative coating material and corrosion resistance. 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. The color steel plate mobile house structure is clean, widely used in large-span factory buildings, warehouses, office buildings, villas, roof additions, air purification rooms, cold storage, shops, kiosks, temporary houses and so on.

The color steel plate activity room is light in weight, can be spliced during installation, and can be cut at will, which determines the difficulty of the installation of the activity room, which can greatly improve the efficiency and save the construction period. 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.

A variety of studies have shown that it has been widely used in foreign countries for more than 40 years: the shelf life of the specially coated color steel plate is 10-15 years, and then the anti-corrosion coating is sprayed every 10 years, and the service life of the prefabricated 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 small part.

Color steel plate for construction is generally hot-dip galvanized steel plate and hot-dip galvanized steel plate as the base material, mainly processed into corrugated plate or composite sandwich plate with polyurethane, which is used for the construction of steel structure factory buildings, airports, warehouses, cold storage and other industrial and commercial. 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.
