what is metal shed buildings?
Simply speaking, metal roof refers to the use of metal plates as the cover of buildings. This phenomenon is very common in our life, especially in some large factories and warehouses, the application of metal roof is very common.
Metal roof refers to the roof form that uses metal plate as the roof material and combines the structural layer and waterproof layer. There are many kinds of metal plates, including galvanized plate, aluminum zinc plate, aluminum alloy plate, aluminum magnesium alloy plate, titanium alloy plate, copper plate, stainless steel plate, etc. the surface of the plate can be treated by baking paint, mainly including pe/pe, smp/pe, hdp\pe, pvdf\pe. Baking paint can enhance the service life of the plate, which are 5-8 years, 10-15 years, 15-20 years, 20-25 years or more respectively.
The thickness is generally 0.4 ~ 1.5mm, and the surface of the plate is generally coated. Due to different materials and coating quality, the service life of some plates can reach more than 50 years. There are various shapes of plates, some are composite plates, that is, the insulation layer is compounded between two layers of metal plates, and some are single plates. During construction, some plates are assembled on site after being processed in the factory, and some are processed on site according to the needs of roof engineering. Some insulation layers can be compounded in the factory or made on site. Therefore, there are various forms of metal sheet roofing, from large public buildings to workshops, warehouses, residences, etc. Therefore, the specification stipulates that the scope of application of metal sheet roof is the roof with waterproof grade I ~ III.
what kind of metal do you use for storage sheds？
Metal roofing generally includes two parts: metal plate and coating. Among them, there are many kinds of metal plates, mainly including single plate and composite plate. Composite plate is a layer of insulation layer added between two metal plates, which plays a more prominent role in actual use. Metal roofing can be assembled before construction or directly on the construction site according to the construction requirements. The types and forms of metal roofing are very rich. Therefore, its application range is very wide, ranging from factory buildings to self owned houses. However, it should be noted that the applicable waterproof grade of metal roofing is 1-3. In practical application, We should abide by this standard.
Metal roofs need to have good anti leakage, snow and water resistance. Therefore, the materials for making metal roofs should be paid special attention to. First of all, in the selection of metal plate materials, it is required that the materials have high plate ribs and a thickness of 0.4-1.5 mm. However, there are still many materials that can be used as metal plates. In addition to the most common steel, aluminum alloy, zinc plate, copper plate, stainless steel plate, aluminum magnesium alloy plate and titanium alloy plate can be used as metal plates of metal roofs, We can choose according to the actual application environment.
Secondly, the selection of coating materials is also very strict. Most of them choose foreign imported color paint as the surface layer of metal roof. Among them, the coating materials applicable to metal plates of different materials are also different. For example, aluminum magnesium manganese alloy plates can choose special color paint for construction imported from the United States and Australia. The service life of this paint can reach 15-20 years, which can effectively protect metal plates, Ordinary alloy plates can choose the common roof coating in Europe and America.
What kind of waterproof materials are used for metal roof waterproofing depends on several commonly used metal roof waterproof materials and their characteristics: high-quality waterproof coating made of pure acrylic lotion and high-quality pigments and fillers, supplemented by a waterproof system formed by sewing polyester cloth. This system can provide perfect solutions for daylighting boards, protruding roof pipes, fan ports, metal plate lap joints, reinforcing screws, gutters and other weak waterproof parts of metal roofs, It has excellent fatigue resistance, aging resistance, low temperature flexibility and excellent elasticity.
