Development and innovation of road guardrail: In recent years, with the rapid development of domestic highway construction, the safety guardrail market has been expanding. However, since the production and use of this product in China is less than ten years, the product standard has only been issued for five or six years, and the national standard has just been issued for two years, the manufacturers have different knowledge of the performance, technical parameters, and production process of this product, resulting in the quality of this product is mixed. Due to the adoption of guardrail products with improper anti-corrosion process in some sections, the guardrail will be rusty 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 China, paint protection was generally 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: galvanization, aluminum plating, plastic coating after galvanization (aluminum) and plastic coating. In rural areas and areas where pollution is not serious, separate hot-dip galvanized layer protection or separate plastic spraying 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 spraying single coating guardrail board may lose its effectiveness before its service life, resulting in a significant increase in guardrail maintenance costs. For hot-dip aluminum guardrail, its corrosion resistance is better than that of ordinary hot-dip zinc 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 galvanizing+plastic spraying, the protection system of hot-dip galvanizing+plastic spraying is an uneconomic method. The double protection system of galvanized sheet+plastic spraying can achieve better anti-corrosion effect in heavily polluted areas, especially in acid rain areas. The service life is greatly extended. It is the most durable protection method.

The road fence is the most important traffic infrastructure. The expressway in China has been developed since the 1980s, and it plays an important role in the development of the national economy and society. It is an important maintenance and safety guarantee facility of expressway.

Road fence material: low carbon steel wire, aluminum magnesium alloy wire and plastic spraying.

Braided and welded; The grid structure is simple, convenient for transportation, and installation is not limited by topographic relief, especially for mountains, sloping fields, and multi curved areas. The product is durable, medium to low price, and suitable for large-scale use.
