1、 Basic characteristics of color steel composite board

1. Light weight: 10-14kg / m2, 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 the load-bearing, bending and compression resistant board of the ceiling enclosure structure; generally, the house does not use beams and columns.
4. Bright color: no surface decoration is required, and the retention period of anticorrosive coating of color galvanized steel plate is 10-15 years.
5. 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 of color steel plate
The base plate of color steel plate is cold-rolled base plate, hot-dip galvanized base plate and electro galvanized base plate. 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 coating plate, embossing plate and printing plate. Color steel plate is widely used in construction appliances, transportation and other industries. For the construction industry, it is mainly used in steel structure factory buildings, airports, warehouses, refrigerated and other industrial and commercial buildings, such as roofs, walls and doors, and so on. Less color steel plate is used in civil buildings.
4、 Structural form of color steel plate
Before forming, there are many types of coil, commonly used: 820 type, 840 type, 900 type and so on! Its composition structure is: protective film (now obsolete), polyester paint, galvanized layer, steel plate (divided into cold-rolled plate and hot-rolled plate), the same sequence on the back.
Color steel plate
General engineering can be divided into single board and composite board, composite board is divided into rock wool composite board and polystyrene composite board. The single board is generally used in workshops or awnings; some single boards will be installed with rock wool, which is called "field composite". The composite plate type wallboard is mostly 950 type, and the roof 970 type or 960 type. 760, 820, 840, 900, 127 or 960 are common for single boards, of which 760 and 820 are fixed by brackets, and other types are fixed by self tapping screws. 760, 820 and 840 are mostly used as top plates, 900 are used as wall panels, 127 or 960 are used for wall panels or top inner anti hanging panel decoration.
Color steel accessories are also indispensable in the project. Ridge tiles, internal corners, external corners, door and window openings, small gutters, expansion joints, etc., are mostly fixed with rivets and sealed with glue.
