Highway fence is the most important transportation infrastructure, our highways are developed from the 1980s, its national economy and social development plays an important influence. Is an important highway maintenance and security facilities. Highway Fence Weaving and characteristics: welded; grid structure concise, easy to transport, install undulating terrain without restrictions, especially for the mountain, slope, bending zone highly adaptive. The product is durable, the price was relatively low for large-scale use. Development and innovation: In recent years, with the rapid development of the domestic highway construction, safety guardrails market expanded. However, since the products in our production and use of time less than a decade, product standards promulgated only in 2056, just two years, the national standards promulgated, the manufacturer of the product performance, technical parameters, production process control varies, resulting in mixed quality of this product. As a result of some sections of the corrosion process of mishandling fence products, ranging from 2012 hours, rusty fence will not only affect the visual effect of the highway, but also greatly shorten the useful life of the fence, but also increased maintenance costs. China's early usually paint protection, then gradually adopted in the form of hot-dip zinc, it is still widely used in a large number of hot-dip zinc-way protection. Fence belonging to a large outdoor use permanent facilities for the protection system should be selected for different atmospheric choose a different protection system. Newly promulgated national standards GB/T18226-2000 "anti-corrosion steel components highway traffic engineering and technical conditions", the barrier protective products are divided into four categories: zinc, aluminum, galvanized steel (aluminum) after plastic, plastic. And pollution is not serious in rural areas, can be used alone or hot-dip zinc coating protective spray protection type fence panels alone, while in heavy industrial areas or coastal urban areas, especially in areas with acid rain, ordinary hot-dip galvanized or spray single coated fence panels not yet reached the useful life may lose their effectiveness, resulting in greatly increased maintenance costs fence. For hot-dip aluminum fence, its corrosion resistance than ordinary hot-dip zinc fence is good, but its process, technology, cost and impact on the environment and other reasons, not very wide range of applications. The use of hot-dip aluminum + spray protection system with respect to hot-dip zinc + spray protection system which is not economical method. Galvanized board + spray dual protection system, available in heavily polluted areas, especially acid rain region to achieve better preservative effect, greatly extend the useful life, most durable protection methods. Highway fence Alias: highway fence, traffic barrier, highway guardrail, highway guardrail. Highway Fence Features: highway fence products are beautiful, durable, non-deformation, quick installation is an ideal metal fence products, both can be made into a permanent network of walls, but also can be used as a temporary isolation, just using different column fixation can be achieved. With anti-corrosion, anti-aging, sunscreen, weather and so on. Can be used for corrosion protection in the form of electroplating, hot dip, spray, dip the way. Highway fence Purpose and scope: mainly used for park / zoo fence, campus / field area enclosures, road traffic isolation, temporary quarantine zone.
