彩钢瓦，又称彩色压型瓦，是采用彩色涂层钢板，经辊压冷弯成各种波型的压型板。它适用厂房、仓库、农宅、特种建筑、大跨度钢结构房屋的屋面、墙面以及内外墙装饰等。济南彩钢瓦厂讲解彩钢瓦的特性如下：

Color steel tile, also known as color profiled tile, is a profiled plate made of color coated steel plate and cold rolled into various wave shapes. It is applicable to the roof, wall and interior and exterior wall decoration of factory buildings, warehouses, agricultural houses, special buildings and large-span steel structures. Jinan Color Steel Tile Factory explains the characteristics of color steel tile as follows:

（1）重量轻：10-14千克/，相当于混凝土现浇屋顶的1/25。

(1) Light weight: 10-14 kg/m2, equivalent to 1/25 of the cast-in-place concrete roof.

（2）导热系数低：λ≤0.041w/mk。（钢筋混凝土的导热系数是1.74W/mk）。

(2) Low thermal conductivity: λ≤ 0.041w/mk。 (The thermal conductivity of reinforced concrete is 1.74W/mk).

（3）强度高：可作天花围护结构板材承重，抗弯抗压，一般房屋不用梁柱。

(3) High strength: it can be used as ceiling enclosure plate to bear the load and resist bending and compression. Generally, beams and columns are not used in buildings.

（4）色泽鲜艳：无须表面装饰，彩色镀锌钢板防腐层保持期在10-15年。

(4) Bright color: no surface decoration is required, and the retention period of the color galvanized steel anti-corrosion coating is 10-15 years.

（5）安装灵活快捷：施工周期可缩短40%。

(5) Flexible and fast installation: the construction period can be shortened by 40%.

（6）氧指数高：OI=32.0（一般认为氧指数大于27属于难燃材料)。

(6) High oxygen index: OI=32.0 (it is generally considered that oxygen index greater than 27 is a refractory material).

彩钢瓦的类型

Type of color steel tile

工程中，一般将彩钢板分为单板和复合板，复合板又分为岩棉复合板和聚苯复合板，有些单板安装时还会再附加岩棉，称作“现场复合”。

In the project, the color steel plate is generally divided into single plate and composite plate, and the composite plate is also divided into rock wool composite plate and polystyrene composite plate. Some single plates will be added with rock wool during installation, which is called "on-site composite".

市面上，多以彩钢瓦的颜色、形状、有效宽度、厚度等区分彩钢瓦。其中，普遍是根据它的有效宽度（为简化加劲板壳计算而引入的一种折合宽度）来区分它的规格。比如，470㎜水平宽度的彩钢瓦称为470型彩钢瓦。单板的常用型号有840型、900型、910型；复合板以950型居多，顶板970型或960型居多。

The color, shape, effective width and thickness of color steel tile are often used to distinguish color steel tile on the market. Among them, its specifications are generally distinguished according to its effective width (a reduced width introduced to simplify the calculation of stiffened plates and shells). For example, the color steel tile with a horizontal width of 470mm is called 470 color steel tile. The common models of boards are 840, 900 and 910; The composite plate is mostly 950 type, and the top plate is mostly 970 type or 960 type.

彩钢瓦作为其他材料具竞争力的取代者，它们使建筑的建造费用降到低水平。同时，多样的颜色、表面结构和镀层，使它具有大的灵活性和可选性。您有相关的需求就来我们网站http://www.jnjgcg.com进行咨询吧！

As a competitive substitute for other materials, colored steel tiles reduce the construction cost of buildings to a low level. At the same time, the variety of color, surface structure and coating make it flexible and optional. Come to our website if you have relevant requirements http://www.jnjgcg.com Consult!
