Metal Roof Covering Systems

  • Metal Roof Covering Systems
Seven-colour/seven-colour roof system is a kind of roof profiled panel with vertical lock edge. It has excellent appearance and excellent performance. It is easy to install and fast without perforation. The roof surface keeps intact and has excellent waterproof performance.

Seven-colour/seven-colour aluminium alloy series roof panels, rolled continuously by aluminium alloy coils, can be processed on site to produce the required length without longitudinal lapping, eliminating the hidden danger of roof leakage.

Seven-color/seven-color aluminium alloy series roofing system, the main material is rolled continuously by 3004 and 3005 aluminium-magnesium-manganese-aluminium alloy coils, the advanced equipment imported from Taiwan in the painting production process, the American technology process, in a closed and dust-free state for precision painting; the coated aluminium coils can be directly processed into roofing panels at the construction site after pressing, which is easy to install, without longitudinal lapping, and plate surface. Maintain integrity; Seven-color/seven-color metal roofing system also has excellent wind pressure resistance, vertical edge locking can eliminate thermal expansion and cold shrinkage stress, no tension, deformations, the overall system without perforation, high anti-corrosion, waterproof performance. At present, the product modelling covers straight plate, fan-shaped plate, normal bend plate and fan-shaped plate, which provides designers with a variety of choices and fully meets the architectural design concept. With the development of society, metal roofing system has gradually become a new star in the industry!
