xAluminum-magnesium-manganese alloy colored aluminum for roofing and exterior walls is generally pre-rolled and has the characteristics of good color difference control, uniform paint film, stable quality, and high environmental protection. Commonly used thicknesses are 0.7-1.2mm. Common models include high vertical sides 65-430 (expanded by 600), 65-420 (expanded by 595), 65-400 (expanded by 575), short vertical sides 25-430 (expanded by 500), 25- 400 (expanded 475) and other A3004 aluminum-magnesium-manganese alloys have the advantages of moderate structural strength, weather resistance, stain resistance, easy bending and welding processing.
65mm high-strength standing seam panels feature a standing locking system. The aluminum alloy T bracket is fixed with purlins, and the top plate and plum blossom bracket of the T bracket are engaged with the trimming machine. In addition, a thermal insulation pad is installed under the T-shaped bracket and fixed with screws to prevent electrochemical reactions between the aluminum components and the steel structure and effectively control the cold bridge effect. High standing seams have better load-bearing capacity and wind resistance than low standing seams, and can better meet the needs of roof design. It is widely used in national projects such as stations, airports, and MRTs; high-end, long-span projects such as stadiums, museums, and exhibition centers.
