The raw material is high-quality low-carbon steel wire (surface treatment such as electro-galvanizing, hot-dip galvanizing, plastic spraying, etc.). If plastic spraying and plastic coating are required, there are a variety of colors to choose from.
Classification of barbed wire
According to the twisting method, single-stranded barbed wire and double-stranded barbed wire are twisted forward and backward.
According to surface treatment, it is classified into galvanized barbed wire and plastic-coated barbed wire. Surface treatment of barbed wire can greatly enhance the anti-corrosion strength of the barbed wire and make it last longer.
The surface treatment of galvanized barbed wire is galvanized and can be divided into electro-galvanized and hot-dip galvanized
The surface treatment of galvanized barbed wire is plastic-coated, and the inner barbed wire is black wire or electroplated wire. Or hot dipped wire.
Barbed wire is used for isolation and protection of pasture boundaries, railways, highways, etc. It is used for anti-theft and isolation protection on the first floor of buildings in factories, private villas, residential buildings, construction sites, banks, prisons, banknote printing factories, military airports, bungalows, etc.

With the rapid development of domestic highway construction, the safety guardrail market continues 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. The manufacturers have different understanding of the performance, technical parameters, and production processes of the product, resulting in the quality of this product. The good and the bad are mixed. In some road sections, due to the use of improperly treated guardrail products with anti-corrosion technology, the guardrails will become rusty in at least 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 increases maintenance costs.
In my country, painting protection was usually used in the early days, and later hot-dip galvanizing was gradually adopted. Hot-dip galvanizing is still widely used for protection. Guardrails are large-scale permanent facilities for outdoor use. The choice of protection system must be based on different atmospheric environments. The newly promulgated national standard/- "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. In heavy industrial areas or coastal urban areas, especially areas with acid rain, ordinary hot-dip galvanized or spray-coated single-coated guardrail panels are used. Guardrails may lose their effectiveness before their useful life is reached, resulting in a significant increase in maintenance costs for guardrails. The corrosion resistance of hot-dip aluminum guardrails is better than that of 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 is the most durable protection method that greatly extends the service life.
