Color steel plate

The substrate of the color steel plate is a cold rolled substrate, a hot-dip galvanized substrate, and an electrogalvanized substrate. The coating types can be classified into polyester, silicon modified polyester, polyvinylidene fluoride and plastisol. The surface state of color steel plates can be divided into coated plates, embossed plates and printed plates. Color steel plates are widely used in construction appliances and transportation industries. For the construction industry, they are mainly used in steel structure factories, airports, warehouses and refrigeration industries. Roofs and doors of commercial buildings, etc., and civil buildings use less color steel plates.

Color steel plate basic type

  • Cold rolled base color coated steel sheet

    The color steel plate produced by the cold-rolled substrate has a smooth and beautiful appearance and has the processing property of the cold-rolled steel sheet.

  • Hot dip galvanized color steel plate

    The hot dip galvanized color steel sheet is a pre-coated galvanized steel sheet, and the product obtained by coating the organic coating on the hot dip galvanized steel sheet is a hot dip galvanized steel sheet. In addition to the protective effect of zinc, hot dip galvanized color coated sheets also have rust preventive properties and have a longer service life than hot galvanized sheets.

  • Hot dip aluminum zinc color coated board

    Hot dip aluminum zinc plate can also be used as a color coated substrate (55% Al-Zn and 5% Al-Zn);

  • Galvanized color coated board

    An electrogalvanized sheet is used as a substrate, and a product obtained by baking with an organic coating is an electrogalvanized color-coated sheet. It has a beautiful appearance and excellent processing properties, so it can be mainly used for household appliances, audio, steel furniture, interior decoration, etc.

Color steel plate structure

Before the molding, it is a coil. After molding, there are many models. The most common ones are: 820, 840, 900, etc.!

There are many brands of color steel plates, and their advantages and disadvantages are different. The general engineering can be divided into single board and composite board, and the composite board is further divided into rock wool composite board and polyphenyl composite board. The use of veneers is generally used in workshops or awnings; some veneers are also attached with rock wool, called “field compounding”. The composite plate type wall panel is mostly 950 type, and the top plate type 970 or 960 is mostly. The boards are common with 760, 820, 840, 900, 127 or 960. The 760 and 820 are mounted by brackets, and the other versions are fixed with self-tapping screws. More than 760, 820, 840 are used as the top plate, more than 900 are used for the wallboard, and 127 or 960 is used for the wallboard or the top inner anti-hanging plate decoration.

Color steel accessories are also indispensable in the project. Ridge tiles, female corners, male corners, door and window pockets, small gutters, expansion joints, etc., are often fixed with rivets and glued.

Advantages and disadvantages of color steel plates in construction

Color steel plates are widely used in many building materials. This material plays an important role in many aspects. Although it has many advantages, its shortcomings also exist.

In the construction site, the color steel plate is used for the outer wall insulation integrated board, and the installation method is simple and quick, and the weight of the color steel plate is much lighter than the brick wall. Although its light weight, it does not mean that its performance is poor, it has a good thermal insulation function, and its thermal conductivity is still very good. If we need colored steel plates to serve as the load-bearing effect of some plates, then its strength is also very good, it can resist bending and resist pressure.

If the color steel plate is installed on the outer wall, its color is very beautiful and bright. At this time, it is not necessary to use other materials to decorate the material, and it is also very convenient and flexible during the installation process, which can make the whole The construction time is greatly reduced. This is a big advantage of color steel plates.

Sandwich material

The sandwich material of the color steel plate is divided into a foam color steel plate (chemical name is polystyrene color steel plate), a rock wool color steel plate, a polyurethane color steel plate, a paper honeycomb sandwich panel, and a glass wool color steel plate.

Foam color steel plate is an organic material, which has the characteristics of light insulation, light weight and easy installation. It has been widely used in recent years. One of the downsides is that the foamed color steel plate is extremely easy to burn and does not meet the national fire protection requirements.

Rock wool color steel plate is a new type of fireproof board with the strongest fire resistance performance in the color steel plate series. It is made of natural rock, blast furnace iron ore slag, etc., which are melted into filaments at high temperature and then solidified. The rock wool color steel plate meets the secondary fire protection requirements of the clean workshop, and is the most ideal structural decorative plate for indoor ceiling and movable house construction. It has a fire resistance of 600 ° C and a fire rating of Class A. It is polystyrene and there is no comparison of polyurethane. Its core material is rock wool that cannot be burned.

The polyurethane sandwich panel is composed of upper and lower color steel plates and intermediate foamed polyurethane. It is one of the most widely used building materials in the construction industry. It has good insulation, heat insulation and sound insulation effects. The polyurethane added with fireproof material does not support combustion.

Glass wool and phenolic foam cored steel plates are slightly more expensive than foam. The phenolic foam material is a polymer organic hard aluminum foil foam product which is formed by foaming a thermosetting phenolic resin. It has the characteristics of light weight, fire prevention, no fire, no smoke, no toxicity, no dripping, wide temperature range (-196~+200°C), no shrinkage and no embrittlement under low temperature environment.
