Metals generally have good plasticity, so metal plates can adapt to roof forms with various complex shapes. The form of metal roof is free, and the color and texture of plates are more selective. Different metal materials and structural practices can be selected according to different architectural styles and creative needs, so as to meet the needs of architectural creation to a great extent.
Profiled metal plate is to make thin (generally 0.6 ~ 1.2mm thick) plates such as aluminum plate, hot-dip galvanized steel plate, color coated steel plate, zinc plate and copper plate into wavy, serrated, trapezoidal and other sections of different forms and specifications through cold and hot rolling. This processing is conducive to improving the stiffness of the plate itself. Profiled metal plate is sometimes vividly called metal corrugated plate, metal broken panel, etc.
Profiled metal sheet for construction is a corrugated steel sheet with cold-rolled steel sheet as the substrate, galvanized or aluminized zinc, supplemented by color coating, rolled and cold formed by forming machine. The common thickness is 0.4 ~ 1.6mm, and the shapes mainly include corrugated, V-shaped, U-shaped, W-shaped and trapezoidal or similar light building plates. Common steel sheets mainly include color coated steel sheet, hot-dip galvanized steel sheet, aluminum zinc alloy steel sheet and other surface treated steel sheets. Stainless steel sheet, aluminum alloy sheet, copper sheet, titanium alloy sheet and so on can also be used.
彩色涂层钢板是以冷轧钢板，电镀锌钢板、热镀锌钢板或镀铝锌钢板为基板经过表面脱脂、磷化、络酸盐处理后，涂上有机涂料经烘烤而制成的产品。彩色涂层钢板的常用涂料是聚酯（PE）其次还有硅改性树脂（SMP）高耐候聚酯（HDP）聚偏氟乙烯（PVDF）等，涂层结构分二涂一烘和二涂二烘，涂层厚度一般在表面20-25u，背面8-10u，建筑外用不应该低于表面20u，背面10u。彩色涂层钢板通常引用的标准是美国ASTM A527（镀锌）ASTM AT92（镀铝锌），欧洲EN/0142，韩国KS D3506，宝钢Q/BQB420。
Color coated steel plate is a product made of cold-rolled steel plate, electro galvanized steel plate, hot-dip galvanized steel plate or aluminum zinc plated steel plate. After surface degreasing, phosphating and complex acid salt treatment, it is coated with organic coating and baked. The common coating for color coated steel plate is polyester (PE), followed by silicon modified resin (SMP), high weather resistant polyester (HDP), polyvinylidene fluoride (PVDF), etc. the coating structure is divided into two coating and one drying and two coating and two drying. The coating thickness is generally 20-25u on the surface and 8-10u on the back. For external use of buildings, it should not be lower than 20u on the surface and 10u on the back. The commonly cited standards for color coated steel plates are American ASTM a527 (Galvanized), ASTM at92 (aluminized zinc), European EN / 0142, Korean KS d3506 and Baosteel Q / bqb420.
