YX50-410-820 specifications: 0.8mm, 1.0mm, 1.2mm, YX50-410-820 common materials: Q235, Q345, YX50-410-820 floor bearing plate, also called YX50-410-820 profiled steel plate , YX50-410-820 steel bearing plate, YX50-410-820 steel floor bearing plate. The earlier name was YX50-410-820 profiled steel plate, and all steel plates pressed and formed by YX50-410-820 pressed plate machine.

YX50-410-820 floor bearing plate is made of galvanized steel plate by YX50-410-820 roll cold bending forming, its cross-section into V-shaped, U-shaped, trapezoidal or similar shapes of waveforms, mainly used as a persistent template, can also be selected for other purposes. The early YX50-410-820 profiled steel plate is mainly used for the roof panel of the factory building surface, and the YX50-410-820 profiled steel plate for the floor is gradually classified as YX50-410-820 floor bearing plate after the backing.

Metal roofing refers to the use of metal plate as the roof material, the structural layer and the waterproof layer into one. There are many types of metal plates, there are galvanized sheets, galvanized sheets, aluminum alloy plates, aluminum-magnesium alloy plates, titanium alloy plates, copper plates, stainless steel plates, etc., the surface of the plate can be treated with baking paint, mainly PE/PE, SMP/PE, HDPPE, PVDFPE these four kinds of baking paint treatment, baking paint can strengthen the service life of the plate, respectively, 5-8 years, 10-15 years, 15-20 years, 20-25 years or more.

The thickness is generally 0.4~1.5mm, and the surface of the plate is generally painted. Due to the difference in material and coating quality, some boards have a life of more than 50 years. The production shape of the board is varied, some are composite panels, that is, the insulation layer is compounded between two layers of metal plates, and some are veneers, during construction, some boards are assembled on site after processing in the factory, and some roof panel manufacturers process on site according to the needs of roofing projects. Some insulation layers are compounded in the factory and can also be made on site. Therefore, metal sheet roofing forms are diverse, from large public buildings to factories, warehouses, residences, etc. are used. Therefore, the specification stipulates that the scope of application of metal sheet roofing is roofing with waterproof grade I ~ III.
