Steel canopy _ Peng Jian Steel (certified) _ Steel Ltd., Zhongshan, Dongguan City, Peng built by steel. Steel Co., Ltd., Dongguan City, Peng Jian (dgpengjian.cn) is specialized in the "Steel" business, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Xu. Some designers often design notes, wrote: using pressure-type high strength bolts 10.9S steel construction, which is a wrong argument. For designers of high strength bolts as long as anti-slip coefficient given level of performance and connectivity to the friction surface material steel company, which does not have to require manufacturers using bolts. "Hongdan twice primer, paint reconcile twice Overlay" This description makes clear paint brand (Hongdan variety), the film thickness is unknown (coating thickness of each layer should be noted), and standards too low, which is the standard 60 years ago, there are still people so used, description of the preservative is not attention. For corrosion, we want to determine the corrosive environment of steel structures; 2, determine the protection of steel structures by protective life; 3, to determine the thickness of the paint and varnish varieties. So, after making steel surfaces should be sand-blasting of steel, can be coated with anti-rust paint after rust and surface paint, to give the corresponding supporting the design of different coating thickness according to the different environments. Such anti-rust steel are better reflected. Advantages seismic steel works: mostly low-rise villas roof sloping roof, so the roof structure is basically made from cold-formed steel members triangular roof truss system, after complete closure plate and plasterboard light steel structural members steel, forming a very strong "board rib structure system", which has a stronger seismic structural system and the ability to resist horizontal loads of light steel structure, suitable for seismic intensity of 8 degrees above areas. Wind: the type of steel construction light weight, high strength, good rigidity, strong deformation. Only one-fifth the weight of buildings brick structure, resistant to 70 meters per second hurricane, so that life and property can be effectively protected. Durability: light steel structure used in all residential component system composed of cold-formed steel, cold rolled steel reinforced using super high-strength galvanized sheet manufacturing corrosion, effectively avoid the impact of corrosion in steel construction and use of the process, increasing the light steel components life. Structural life of up to 100 years. Insulation: insulation materials used in fiberglass cotton-based, with good insulation effect. For exterior wall insulation board, effectively prevent the wall of the "cold bridge" phenomenon, to achieve a better insulation effect. R15 insulation around 100mm thick cotton thermal resistance can be equivalent to 1m thick brick wall. Noise: noise effect is an important indicator to assess residential, light steel system installed windows are hollow glass, sound insulation, sound insulation up to 40 decibels; the wall by the light steel keel, gypsum board insulation materials consisting soundproofed the effect of up to 60 decibels.
