随着我国钢产量的增长及国家对钢结构产业政策的调整,钢结构建筑的兴建日益增多.轻型钢结构建筑以其自重轻、抗震性能好、施工快和污染小等独特的发展优势，已经广泛应用于工业厂房、库房、体育馆、展览馆等工程项目中。

With the growth of steel output in China and the adjustment of national steel structure industrial policy, the construction of steel structure buildings is increasing. Light steel structure building has been widely used in its light weight, good seismic performance, fast construction and small pollution, and is widely used in industrial factories, warehouses, gymnasiums, exhibition halls and other engineering projects.

彩钢屋面由结构层、保温层和面板层构成，结构层以c型钢和z型钢为主；保温层现场填充时多为玻璃丝棉、岩棉，当保温层为聚苯或聚氨酯时，通常与彩钢板在工厂内预先复合成型（称为彩钢复合夹芯板）；面板层主要有彩色压型钢板、彩钢复合夹芯板。依据面板层的选用不同，彩钢屋面可大致分为单层彩钢板屋面、双板现场复合屋面和彩钢复合夹芯板屋面。

Color steel roof is composed of structure layer, insulation layer and panel layer, structure layer is mainly c-type steel and z-type steel; insulation layer is filled with glass wool, rock wool, when the insulation layer is polystyrene or polyurethane, usually with color steel plate in the factory (called color steel composite sandwich plate); the panel layer mainly has color pressure steel plate, color steel composite sandwich plate.According to the different selection of panel layer, color steel roof can be roughly divided into single-layer color steel plate roof, double plate site composite roof and color steel composite sandwich board roof.

彩钢屋面一般采用彩钢压型板或彩钢复合夹芯板。彩钢压型板是采用镀锌（或镀铝锌）基板涂覆彩色涂层后形成的彩涂板轧制成型。单层彩钢压型板重量轻、强度高、制作安装方便，但导热系数大，隔音效果差；对有保温、隔音要求的屋面，可采用双层彩钢压型板中间填充保温材料（如玻璃丝棉、岩棉等）或采用彩钢复合夹芯板，彩钢夹芯板为双层彩钢板与保温材料在工厂通过粘结剂预先复合成型，因此具有抗弯刚度高、整体性能好等优点，使用范围越来越广。

Color steel roof generally adopts color steel pressing plate or color steel composite sandwich board.Color steel pressing plate is formed by using galvanized (or galvanized) substrate coated with color coating.Single-layer color steel pressing plate light weight, high strength, convenient production and installation, but large thermal insulation coefficient, poor sound insulation effect; the roof, double-layer color steel pressing plate can be filled with insulation materials (such as glass wool, rock wool, etc.), or the color steel composite sandwich plate, color steel sandwich plate for double-layer color steel plate and insulation material in the factory through binder composite molding, so with high bending stiffness, good overall performance and other advantages.

彩钢压型板基板厚度一般为0.3mm～1.0mm，压型后具有一定的刚度和承载能力，屋面外板应尽量选用厚度较大、镀锌基层质量好的彩板轧制。屋面常用的压型钢板规格有YX25-205-820、YX25-210-840、YX75-380-760、YX48-410-820、直立锁边475型等多种板型。

The thickness of color steel pressing plate substrate is generally 0.3mm~1.0mm, with a certain stiffness and bearing capacity, the roof outer plate should try to choose a large thickness, galvanized base quality color plate rolling.The commonly used pressure steel plate roof specifications are YX25-205-820, YX25-210-840, YX75-380-760, YX48-410-820, upright lock edge 475 and other plate types.

佛山市万庆物资彩钢板具有十年不变色，外观高雅等优异性能，能很明显地美化产品外观、大幅度提升产品档次。

Foshan Wanqing material color steel plate has many years do not change color, elegant appearance and other excellent performance, can obviously beautify the appearance of the product, greatly improve the product grade.
