Corrugated roof steel plate refers to the color coated steel plate, color coated steel plate is a kind of organic coating with steel plate. Color steel plate is divided into veneer, color steel composite board, floor board and so on. Widely used in large public buildings, public buildings, activities board room, and integrated housing walls and roofs.
Corrugated roof steel plate basic features:
1. Light weight: 10-14 kg / square meter, equivalent to 1/30 of the brick wall.
2. Thermal insulation: core thermal conductivity: λ <= 0.041w / mk.
3. High strength: can be used for smallpox envelope structure bearing, bending compression; general housing without beams and columns.
4. Bright color: no surface decoration, Corrugated Roofing Steel Sheet color galvanized steel coating to maintain a period of 10-15 years.
5. Flexible installation: the construction period can be shortened by more than 40%.
6. Oxygen index: (OI) 32.0 (provincial fire product quality inspection station).
Main types: color plate of the substrate for the cold-rolled substrate, Corrugated Roofing Steel Sheet hot-dip galvanized substrate and electro-galvanized substrate. Coating types can be divided into polyester, silicon modified polyester, polyvinylidene fluoride and plastic sol. Corrugated Roofing Steel Sheet The surface condition of the color steel plate can be divided into coated board, embossed plate and printing plate. The color steel plate is widely used in the construction of household appliances and transportation industry. Corrugated Roofing Steel Sheet The construction industry is mainly used for steel industry, airport, warehouse and freezing industry. Commercial buildings of the roof walls and doors, etc., civil buildings using less color plate. And steel difference between it and steel is different from the composition of the material, suction stone can be sucked. Strictly speaking, steel and Caigang in the metal properties and surface treatment is not a good distinction, because the same; so the distinction between the market mainly in the profile structure. Because it is an ordinary carbon steel material, the magnets can suck. In addition to add that stainless steel is based on the low carbon steel by adding chromium (greater than or equal to 13%) after the product, so the suction stone can not suck.
Corrugated Roof Steel Plate Classification
Pressure plate is usually based on the application site, plate wave height, lap structure, and material, etc., there are a variety of classification. Common classification of the following categories:
(1) by application site classification - divided into roof panels, wall panels, floor boards and ceiling panels and so on. The use of color plates at the same time use the wall to do decorative panels, Corrugated Roofing Steel Sheet architectural decoration effect is relatively new and unique.
(Wave height ≤ 70mm), medium wave plate (wave height <70mm) and low wave plate (wave height <30mm)
(3) according to the substrate material classification - divided into hot-dip galvanized substrate, hot-dip galvanized and hot-dip galvanized aluminum substrate.
(4) According to the slab structure classification - divided into lap, Corrugated Roofing Steel Sheet undercut and withholding structure. Which is undercut, withholding, high wave board should be used for high water requirements of the roof; lap in the high-wave plate galvanized sheet to use the floor plate; lap low wave board should be used as a wall panel.
Characteristics of Corrugated Roof Steel
Product performance: color plate thickness 0.2mm ~ 1.0mm
Effective width: 608mm, 760mm, 820mm, 900mm, 950mm, 960mm, 1025mm, etc.
Corrugated roofing steel use
(1) handsome in appearance, rich colors, strong decorative, Corrugated Roofing Steel Sheet flexible combination of different, can be expressed different
The architectural style;
(2) light weight (6 ~ 10kg / m²) high strength (yield strength of 250 ~ 550MPa), has a good skin stiffness, waterproofing agent good seismic performance;
(3) high quality of factory products
