彩色压型钢板是由彩钢板经轧制而成的各种波形。压型钢板由彩钢板经轧制、冷弯成各种波形而成。适用于工业及民用建筑、仓库、特种建筑、大跨度钢结构建筑的屋面、墙面及内外墙装饰。具有重量轻、强度高、色彩丰富、施工方便快捷、抗震、防火、防雨、使用寿命长、免维护等特点。它已经得到了广泛的推广和应用。
压型钢板通常按应用部位、板波高、搭接结构和材料等进行分类。常用的分类方法如下：
（1） 根据应用部位，可分为屋面板、墙板、楼承板、天花板。同时，采用彩钢板作为墙面装饰板，建筑装饰效果新颖独特。
（2） 按波高分类：高波片（波高≥70mm）、中波片、低波片（波高<30mm）
（3） 根据基材的材料分类，可分为热镀锌基材、热镀铝锌和热镀锌铝基材等。
（4） 根据板节点的构造，可分为搭接、咬边和压缝。其中，防水要求高的屋面板宜采用咬边受压的中、高波板；楼板宜采用中、高波板搭接的镀锌板；墙板宜采用搭接的低波板。
目前，市场上彩色压型钢板种类繁多。一般来说，每一个钢结构制造商都有自己的研发专用型。压型钢板的选型可从以下几个方面考虑：
1、 根据建筑立面的要求选择板型。
在实际施工图中，只能怪一般只给出了金属屋面和墙体的范围和墙板的铺设方法（水平或垂直铺设），很少规定板型。因此，有必要根据建筑物的立面要求选择合适的楼板类型。例如：墙板需要垂直放置，可以选择yx15-225-900和yx25-210-840；对于立面效果为平房的项目，建议采用yx25-200-1000，使建筑立面更加美观，施工更加方便。如需水平摊铺，可采用yx18-76-836、yx18-63.5-825型波浪式，也可采用yx38-310、yx58-310、yx50-373型隐蔽式
2、 根据绝缘棉厚度选择板型。
不同的建筑物应位于不同的地方，有不同的用途和不同的绝缘要求。绝缘棉厚度确定后，根据绝缘棉厚度选择板型。当墙体保温棉厚度大于或等于100 mm时，应选用高度辅助相对较高的墙板，如yx28-820和yx25-210-840为前者，宜采用反向碾压。当墙体保温棉厚度大于50毫米时，不宜选用高高的小波纹板，否则墙体易产生凹凸不平，影响建筑美观。当屋面保温棉厚度大于100mm时，可选用yx75-760。当保温棉厚度大于150 mm时，应尽量选用双层屋面。如果选用yx75-760作为屋面板（注意这是一种无钉滑动支撑的板），即使没有保温要求也要加50毫米厚的保温棉，因为没有保温棉会引起屋面板和檩条的撞击产生声音，再加上保温棉，绝缘棉
Color profiled plate is made of color coated steel plate, which is rolled into various wave shapes. The profiled plate is made of color coated steel plate, which is rolled and cold bent into various wave shapes. It is suitable for the roof, wall and interior
and exterior wall decoration of industrial and civil buildings, warehouses, special buildings and large-span steel structure buildings. It has the characteristics of light weight, high strength, rich color, convenient and fast construction, earthquake
resistance, fire protection, rainproof, long service life and maintenance free. It has been widely used Promotion and application.
Profiled steel plates are usually classified according to the application position, plate wave height, overlapping structure and material. Common classification methods are as follows:
(1) According to the application parts, it can be divided into
roof panel, wall panel, floor bearing plate and ceiling plate. At the same time, the color steel plate is used as the wall decoration plate, and the architectural decoration effect is novel and unique.
(2) Classification by wave height: high wave
plate (wave height ≥ 70mm), medium wave plate and low wave plate (wave height < 30mm)
(3) According to the material classification of the substrate, it can be divided into hot-dip galvanized substrate, hot-dip aluminized zinc and hot-dip galvanized
aluminum substrate, etc.
(4) According to the structure of slab joint, it can be divided into lap joint, undercut joint and compression joint. Among them, the medium and high wave plates with undercut and compression should be used as roof panels
with high waterproof requirements; the galvanized plates with overlapping medium and high wave plates should be used as floor plates; the low wave plates with overlapping should be used as wall panels.
At present, there are many types of color profiled
steel plates in the market. Generally, each steel structure manufacturer has its own special type for research and development. The selection of the type of profiled steel plates can be considered from the following aspects:
1、 Select the plate
type according to the requirements of the building facade.
In the actual construction drawing, it can only be blamed that only the scope of metal roof and wall and the laying method of wall panel (horizontal or vertical laying) are generally given,
and the board type is rarely specified. Therefore, it is necessary to select the appropriate slab type according to the facade requirements of the building. For example: the wall panel needs to be placed vertically, you can choose yx15-225-900 and yx25-210-840;
for the project with the facade effect of flat building, it is recommended to use yx25-200-1000, so that the facade of the building is more beautiful and the construction is more convenient. If horizontal paving is required, wave type yx18-76-836 and
yx18-63.5-825 can be used, and hidden type yx38-310 or yx58-310, yx50-373 can also be used
2、 Selectthe board type according to the thickness of insulating cotton.
Different buildings should be located in different places with different purposes
and different insulation requirements. After the thickness of the insulating cotton is determined, the board type shall be selected according to the thickness of the insulating cotton. When the thickness of the wall insulation cotton is 100 mm or more,
the wall panel with relatively high height assistance shall be selected, for example, yx28-820 and yx25-210-840 shall be selected as the former, and it is better to reverse rolling. When the thickness of wall insulation cotton is greater than 50 mm, it
is not suitable to choose the small corrugated plate with high height, otherwise the wall is prone to be uneven, affecting the beauty of the building. When the thickness of roof insulation cotton is greater than 100mm, yx75-760 can be selected. When the
thickness of insulation cotton is greater than 150 mm, double-layer roof shall be selected as far as possible. If yx75-760 is selected as the roof panel (note that this is a type of board without nail linked by sliding support), 50mm thick insulation
cotton shall be added even if there is no insulation requirement, because no insulation cotton will cause the impact of roof panel and purlin to produce sound, plus insulation cotton, insulation cotton will produce resistance to support the roof panel,
and yx75-760 link will not produce fatigue damage. Changzhou floor bearing plate
