Superiority of arched metal roof:
Span, without beam, purlin, without support, good headroom and interior space is excellent.
2, the design and construction cycle is short, single shift 400m2 construction speed is superior.
3, color steel molding, mechanical lock side connected to the natural drainage absolutely no leakage, corrosion, corrosion resistant, waterproof superior performance.
4, the overall performance is good, reasonable structure, wind, rain, snow, seismic performance is superior, high safety factor.
5, light weight, low cost, less investment, quick span of 20m above the roof than the traditional structure of the roof per m2 section owned 30% of the overall economic efficiency is superior.
6, set roof insulation, insulation, ventilation and lighting in one self-contained, adaptable, and widely used.
7, the force reasonable way, the safety margin of the life cycle of 30 years, 10-year warranty period, maintaining superior performance.
