Shanghai-wing membrane structure tarpaulin material is a membrane structure, membrane biggest feature is the high strength, durability, fire retardant, good self-cleaning, UV stable, long life, usually 15-30 years. Has a high transmittance, light transmission rate of 13%, with little heat reflectance of 73%, the amount of heat absorbed. Product Name: toll stations membrane structure Material: Q235 steel models; double-sided PVC membrane / PVDF membrane Color:?? White, yellow, red, blue, etc. size: according to the shape of computing products require the use of materials: 2) film?? Timber -? sided PVC synthetic / PVDF membranes are polyester fiber membrane or glass fiber as fabric (Layer), and then coated with a surface coating, which together with high quality PVC construction textile composition, and its use life in general can reach 15-30 years. ? G volume: 1050 g / m Thickness: 0.6mm - 1.2mm Fire Level:?? National B1 level standard (flame retardant, self-extinguishing three seconds away from the fire, in line with German and French M2 standard DIN4102 B1) highly efficient defense?? UV, waterproof, good self-cleaning. ?? Membrane structure characteristics:? 1) Lightweight: prestressed membrane structures rely on to maintain the stability of the structure, so the weight is much less than traditional structures. ? 2) modeling and diverse: the changing of the support structure and the shape of the flexible membrane allows the membrane structure of diverse, reflecting the structure of the United States, coupled with rich colors can create a freer and richer architectural form architectural language. ? 3) Security: flexibility of the film structure so that it can be carried in the most favorable form of external loads. In the role of wind load or under snow load can have a huge shift occurred without permanent deformation, in order to effectively resist external load; under lateral loads such as earthquakes can maintain good stability; even collapse accident the risk of the membrane structure is also more traditional building small structures. ? 4) Fire: membrane material widely used today can satisfy the demand for fire protection, otherwise excellent / flame and heat resistance, to France, Germany, the United States, Japan and other countries standards. ? 5) Self-cleaning: After special surface treatment of PVC membrane has good self-cleaning properties, rainwater will gather into a stream of water droplets on the surface, so to get a natural membrane surface cleaning. ? 6) Economy: -? Light transmission properties of membranes may provide for the construction of the required illumination, energy-saving effect, and meet some of the commercial building and to highlight the requirements for illumination. ? - Membrane architecture peculiar shape and a clear night effect "building may know" and commercial effect. Transmission gorgeous landscape at night by lantern formation can be achieved by good advertising effectiveness. ? - Membrane structure lower raw material costs than conventional construction, and materials with less material, so the cost is lower than the average building. ? 7) short duration: Membrane construction projects all processing and production are completed in the factory, reducing on-site construction time, to avoid cross-construction, construction period is short compared to the traditional architecture. ?
