1, awnings retractable awnings: used in outdoor shade, it has retractable freedom, strong wind, large shade area, corrosion and rust and other characteristics. Fabric with new fabric shade, rain, mildew, resist heat and ultraviolet rays, the system part of the useful life of more than seven years for home terraces, shops, hotels, sports venues use external shading. There are three categories of products, more than 30 kinds of fabrics to choose from, the fabric above may need to print LOGO or advertising slogan. According to Environment size custom 1) When building a higher standard, the following conditions are met 1 to 2 shade measures should be taken (1) Interior (outside) air temperature reaches or exceeds 29 ℃; (2) the solar radiation intensity> 240kcal / m2 · h (1004.6kJ / m2 · h); (3) the depth of the indoor sunlight> 0.5m; (4) Interior sunlight longer than 1h. 2) awnings suitable for external low-rise, multi-story building door window shade. Should not be used in high-rise building exterior shading. 3) the relationship between form and material specifications of shade material, thickness, size and form, fixtures, motor power (When using electric), use of premises of pressure size are interrelated, to be based on specific project conditions , the professional manufacturer for technical information, after considering the selection. 4) issues related to safety and shading systems connected to the practice of its main building, mine measures required by the project designer in accordance with the specific project conditions, joint research and professional manufacturer determines and is responsible for. 5) Those who choose shade system with shutter box, you should consider the impact roller shutter boxes placed at different locations on the wall energy. 6) For vehicles equipped with automatic control system, general requirements must be installed wind control, rain control sensors, light control can be selected according to specific circumstances. Manual drive mode generally apply to exterior shading often unmanned sites. 7) recommend the use of dark fabrics (or the dark side of fabric facing outdoor), in order to achieve better shading effects. 8) fabric performance requirements (1) fabrics should ensure dimensional stability, not deformed. (2) the fabric surface smooth, ensure rolling freely, prevent fabrics deviation, folds or rewinding is not smooth and other phenomenon. (3) The fabric should have sufficient tensile and tear strength to prevent the danger of being torn appears under adverse weather conditions. The connection between the fabric (4) shall be hinged frequency welding process, in order to ensure adequate strength fabric. (5) fabrics should ensure good color solid degree. (6) the fabric surface should have a certain anti-pollution performance, and easy to clean, easy to maintain. 9) Fabric Type: polyester coated fabrics, glass fibers coated fabrics.
