guardrail The network is a more important transportation infrastructure. China's expressways have been developed since the 1980s, and they play an important role in the development of the national economy and society. It is an important maintenance and safety guarantee facility of expressway.
Material of highway guardrail net: low carbon steel wire Aluminium magnesium alloy Silk, spray molding.
Weaving and characteristics of highway fence mesh: woven and welded; The grid structure is simple, convenient for transportation, and installation is not limited by topographic relief, especially for mountainous areas, sloping fields, and multi bend areas. The product is durable, medium to low price, and suitable for large area use.
Development and innovation: In recent years, with the rapid development of domestic highway construction, the safety barrier market has been expanding., However, since the product has been produced and used in China for less than ten years, the product standard has only been issued for five or six years, and the national standard has only been issued for two years, the manufacturers have different knowledge of the product's performance, technical parameters, and production process, resulting in the quality of this product being mixed. Due to the adoption of guardrail products with improper anti-corrosion process in some sections, the guardrail will be rusted for at least one or two years, which not only affects the visual effect of the expressway, but also greatly shortens the effective service life of the guardrail, and also increases the maintenance cost. In our country, painting protection was usually adopted in the early period, and then hot-dip galvanizing was gradually adopted. Now, hot-dip galvanizing is still widely used for protection. Guardrail is a large long-term facility for outdoor use, and different protection systems should be selected for different atmospheric environments. The newly issued national standard GB/T18226-2000 Technical Conditions for Anticorrosion of Steel Members of Highway Traffic Engineering divides the protection of guardrail products into four categories: zinc plating, aluminum plating, plastic coating after zinc plating (aluminum), and plastic coating. In rural areas and areas with less serious pollution, separate hot-dip galvanized layer protection or separate plastic sprayed protective guardrail board can be used. In heavy industrial areas or coastal urban areas, especially in areas with acid rain, ordinary hot-dip galvanized or plastic sprayed single coating guardrail board may lose its effectiveness before its service life, resulting in a significant increase in the maintenance cost of the guardrail. For hot-dip aluminum guardrail, its corrosion resistance is better than that of ordinary hot-dip galvanized guardrail, but its application scope is not very wide due to its process, technology, cost and environmental impact. Compared with the protection system of hot-dip aluminized plastic spraying, the protection system of hot-dip aluminized plastic spraying is an uneconomical method. With plating Zinc plate The double protection system of plastic spraying can achieve better anti-corrosion effect in heavily polluted areas, especially in acid rain areas, and can greatly extend the service life. It is a more durable protection method.
Highway guardrail net alias: highway guardrail net, traffic guardrail, highway guardrail board, highway guardrail.
Features of highway guardrail net products: the highway guardrail net products are beautiful, durable, non deformable, and fast to install. It is an ideal metal guardrail product. It can be made into a long-term net wall, and can also be used as a temporary isolation net. It can be achieved by using different column fixing methods. It has the characteristics of anti-corrosion, aging relief, sun resistance, weather resistance, etc. For anti-corrosion, electroplating, hot plating, plastic spraying and plastic dipping can be used.
Purpose and scope of use of road fence: mainly used for park/zoo fence, campus/site enclosure, road traffic isolation, and temporary isolation belt.
Road fence material: high-quality low-carbon steel wire, stainless steel wire aluminium alloy Silk PVC Silk.
Road fence mesh weaving and characteristics: it is crocheted, with uniform mesh, flat mesh surface, beautiful and generous, wide mesh width, thick wire diameter, corrosion resistance, long service life, simple weaving, beautiful and practical.
Use of road fence: protection of mechanical equipment, highway fence, fence for stadiums, fence for green belts on roads.
High speed fence is also called highway fence
Material: low carbon steel wire
High speed fence mesh weaving and characteristics: woven and welded.
Features of high-speed guardrail net: anti-corrosion, anti-aging, sun resistance, weather resistance, etc. The anti-corrosion forms of guardrail net surface include electroplating, hot plating, plastic spraying, plastic dipping, and plastic dipping after galvanizing.
Effect:
(1) Reasonable structure and excellent function.
(2) Coordinate with the landscape and have beautiful form.
Anticorrosion treatment of high-speed guardrail net: after rust removal, polishing, passivation, vulcanization and other processes, plastic plating treatment is adopted. The color is fruit green, and the coating thickness is 0.6~1.6mm. The plating powder is imported weather resistant resin powder with good aging relieving performance. The coating must be consistent in color, smooth in surface, and free of sagging, dripping or excessive caking. The surface of plated parts shall be free of defects such as missing plating and iron exposure.
The surface color of high-speed guardrail net can be selected: white, green, dark green, grass green, black, blue, color, etc.
