Whether the color steel plate coil belongs to the special steel coil for purification. Special steel coil for purification is usually provided with special coating and anti-corrosion coating, which is easy to clean, antibacterial and dust-free. Therefore, the choice of color steel plate is not important, mainly because whether special color steel coil for purification is used in the production process.

板材的基材有冷轧基材、热镀锌基材和电镀锌基材。涂料类型可分为聚酯、硅改性聚酯、聚偏氟乙烯和增塑溶胶。板材的表面状态可分为涂层板、压花板被广泛应用于建筑电器、交通运输等行业。对于建筑行业，主要用于工厂、机场、仓库、制冷等工商业建筑的屋顶、墙壁、门，而彩钢板很少用于民用建筑。

The base materials of plates include cold rolled base materials, hot-dip galvanized base materials and electro galvanized base materials. Coatings can be divided into polyester, silicon modified polyester, polyvinylidene fluoride and plasticized sol. The surface state of plate can be divided into coated plate and embossed plate, which are widely used in construction electrical appliances, transportation and other industries. For the construction industry, it is mainly used for the roofs, walls and doors of industrial and commercial buildings such as factories, airports, warehouses and refrigeration, while color steel plates are rarely used in civil buildings.

板材广泛应用于钢结构的屋顶、墙壁、天花板和空气洁净室的隔断，市场上也会有一些厂家用钢卷来造假板材对于一些对不是特别熟悉的采购商和用户来说，通常很难区分，这也是造成一些厂家在彩钢板的价钱低的因素。

Plate is widely used in the partition of steel structure roof, wall, ceiling and air clean room. Some manufacturers will use steel coil to fake plate in the market. It is usually difficult to distinguish between some buyers and users who are not particularly familiar with it, which is also the factor causing the low price of color steel plate by some manufacturers.

一般彩钢板可分为单板和复合板，复合板可分为岩棉复合板和聚苯乙烯复合板。单板一般用于车间或工棚；一些单板安装有额外的岩棉，这被称为“现场复合”。950型是大多数的复合墙板，970或960型是大多数的屋顶板。760、820、840、900、127或960是常见的单板，其中760和820用支架固定，其他类型用自攻钉固定。760、820和840多用作顶板，900用作墙板，127或960用作墙板的装饰或顶部的倒挂板。

Generally, color steel plate can be divided into single plate and composite plate, and composite plate can be divided into rock wool composite plate and polystyrene composite plate. Veneer is generally used in workshops or sheds; Some veneers are equipped with additional rock wool, which is called "field composite". Model 950 is the majority of composite wall panels, and model 970 or 960 is the majority of roof panels. 760, 820, 840, 900, 127 or 960 are common veneers, in which 760 and 820 are fixed with brackets and other types are fixed with self tapping screws. 760, 820 and 840 are mostly used as top plates, 900 as wall plates, 127 or 960 as decoration of wall plates or upside down plates at the top.
