Highway fence is the most important transportation infrastructure, our highways are developed in the 1980s, its national economic and social development plays an important effect. Is an important highway maintenance and security facilities. Material selection of low carbon cold drawn steel wire, aluminum-magnesium alloy wire, galvanized wire. Common Specifications: The 3.5mm-6.0mm high strength carbon steel welding. Mesh: 50mm × 100mm (can be customized according to customer requirements) rectangular hole: 50 × 100,75 × 150,50 × 200,60 × 150 most common. Column: 48mm × 1.0-2.0mm thick tube. Borders: 20 × 30 or 20 × 40mm rectangular section pipe; 0.8/1.0/1.2/1.5mm thick square tube welded compiled Weaving and characteristics: grid structure concise, easy to transport, install undulating terrain without restrictions, especially for mountain, slope, bending zone highly adaptive. The product is durable and the price was relatively low for large-scale use. Development of innovative highway fence highway fence With the rapid development of the domestic highway construction, safety fence market continues to expand. However, because the product in our production and use of time less than a decade, product standards issued only five or six years, the national standards promulgated just two years, the manufacturer of the product performance, technical parameters, not the same production process control, resulting in the quality of the product varies greatly. 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 effects freeway, but also greatly shorten the useful life of the fence, but also increases the maintenance costs. Early country usually paint protection, then gradually take the form of hot-dip zinc is still widely used in a large number of hot-dip zinc way protection. Fence belonging to a large long-term outdoor use of facilities, the choice of the protection system to choose a different protection system for different atmosphere. National Standard GB/T18226-2000 issued a new "anti-corrosion steel components highway traffic engineering and technical conditions", the protective fence products are divided into four categories: galvanized steel, 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 protective type fence panels alone, and in heavy industrial areas or coastal urban areas, especially those in areas of acid rain, hot dip galvanized or spray ordinary 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 conventional hot-dip zinc fence, but the reasons for its technology, technical, cost and environmental impact, etc., is not very wide range of applications. The use of hot-dip aluminum + spray protection system, as opposed to hot-dip zinc + spray protection system is a non-economic approach. Spray galvanized sheet + double protection system can be particularly heavy acid rain polluted areas in the region to achieve a better preservative effect, greatly extending the useful life, most durable protection methods.
