Supply of road guardrails/Anhui road guardrail installation/Hefei road guardrail network maintenance

Road guardrail network is the most important transportation infrastructure. my country's highways 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 facility for highways.
Road guardrail net material: low carbon steel wire, aluminum-magnesium alloy wire, sprayed with plastic.
The braided and welded grid structure is simple, easy to transport, and the installation is not restricted by terrain fluctuations. It is especially adaptable to mountains, slopes, and multi-bend areas. This product is durable, moderately priced and suitable for large areas.
Innovation in the development of road guardrail networks: In recent years, with the rapid development of domestic highway construction, the safety guardrail market has continued to expand. However, because this product has been produced and used in my country for less than ten years, the product standard was promulgated only five or six years ago, and the national standard was promulgated just two years ago, manufacturers have different understandings of the product's performance, technical parameters, and production processes, resulting in this The quality of a product varies from good to bad. Due to the use of guardrail products with improper anti-corrosion technology on some road sections, the guardrails will become rusty in as little as one or two years, which not only affects the visual effect of the highway, but also greatly shortens the effective service life of the guardrails, and also increases the cost of the guardrails. Maintenance costs. In the early days of our country, paint protection was usually used, and later hot-dip galvanizing was gradually adopted. Nowadays, hot-dip galvanizing is still widely used for protection. Guardrails are large-scale permanent facilities for outdoor use. The choice of protection system should be based on different atmospheric environments. The newly promulgated national standard B/- "Technical Conditions for Anticorrosion of Steel Components in Highway Traffic Engineering" divides the protection of guardrail products into four categories: galvanized, aluminized, galvanized (aluminum) followed by plastic coating, and plastic coating. In rural areas and areas where pollution is not serious, separate hot-dip galvanized layer protection or separate spray-coated protective guardrail panels can be used. However, in heavy industrial areas or coastal urban areas, especially areas with acid rain, ordinary hot-dip galvanized or spray-coated single-layer guardrail panels can be used. Coated guardrail panels may lose their effectiveness before their useful life is reached, resulting in a significant increase in guardrail maintenance costs. For hot-dip aluminum guardrails, its corrosion resistance is better than ordinary hot-dip galvanized guardrails, but its application range is not very wide due to reasons such as process, technology, cost and environmental impact. The protection system using hot-dip aluminum + plastic spraying is an uneconomical method compared to the protection system of hot-dip zinc + plastic spraying. The dual protection system of galvanized sheet + plastic spraying can achieve better anti-corrosion effects in heavily polluted areas, especially acid rain areas, and the service life is greatly extended. It is the most durable protection method.
