How can highway guardrail nets be used longer in outdoor use? Highway guardrail nets are widely used today, but the anti-corrosion of guardrail nets has always been a concern. Recently, hot-dip galvanizing of highway guardrail nets has been studied. This not only ensures quality and increased service life. Triangular bending guardrail nets have been widely used for decorative protection on expressways, highways, railways, airports, factories, factories, residential quarters, ports and terminals, municipal oases, garden flower beds, and oases. Guardrail net is a way to establish an online connection and become an advanced guardrail product. It is mainly divided into three categories: galvanized, spray-coated and dip-coated. This product is welded with high-quality low-carbon steel wire. The corrosion conditions include electroplating, hot plating, plastic spraying, and plastic dipping. The products are beautiful, sturdy and well-corroded. Specialized in railways, highways, and landfills, it has the characteristics of durability, beauty, broad vision, and excellent protection performance.
The guardrail net is a product for professional protection. It is durable, beautiful, has a broad vision, and has excellent protective properties. The mesh body is cast in concrete as one of the pillars, and overall, the project cost is low. High-strength overall stability, the net body color plastic layer has excellent corrosion resistance and decorative effect, making the net tail ring overall harmonious and beautiful. Product features: anti-corrosion, anti-aging, weather resistance, sun resistance, etc. Anti-corrosion coating, in the form of hot electroplating, plastic spraying, and plastic dipping, is mainly used as another barrier on closed railway highways, and is used in gates in development zones. This product is mainly used for isolation and protection at both ends of the railway. It is a closed barrier product for railway professional places. It has the characteristics of durability, beauty, vision and openness, and has excellent protection function. All railway isolation fences are constructed using concrete pouring, which ensures safety, clean columns, low project cost and is comprehensive. High-strength overall stability, the net body color plastic layer has excellent corrosion resistance and decorative effect, making the net tail ring overall harmonious and beautiful.
When installing the guardrail net, the construction unit should accurately grasp the various construction drawings and the precise positions of the various pipes buried in the roadbed. During the construction process, any damage to the underground equipment is not allowed. If the railway guardrail net is driven into columns, When it is too deep, the column must not be pulled out and corrected. The foundation must be re-tamped before driving in, or the position of the column must be adjusted. When approaching the depth during construction, attention should be paid to controlling the hammering intensity. For railway guardrails, flanges should be installed, and attention should be paid to the positioning of the flanges of the guardrail network and the control of the top elevation of the columns. Guardrail network is a railway safety equipment installation project and an important part of the appearance quality of highways. The intrinsic quality of the railway guardrail network lies in the raw materials and processing process. Its appearance quality depends on the construction process. During the construction, we must pay attention to the combination of construction preparation and pile driver, constantly sum up experience, and strengthen construction management, so that the installation quality can be guaranteed. Highway guardrail net products have bright colors, beautiful appearance and environmental protection, super corrosion resistance, salt spray resistance, temperature and heat resistance, weather resistance, bright colors, high strength, long service life, and low maintenance and repair costs.
Regarding the cost of hot-dip galvanizing treatment for highway guardrail nets: the cost of hot-dip galvanizing for rust prevention is lower than the cost of other paint coatings; the durability of highway guardrail nets: in suburban environments, standard hot-dip galvanized anti-rust The thickness of the rust can last for more than 50 years without repair; in urban or offshore areas, the standard hot-dip galvanized anti-rust layer can last for 20 years without repair; the reliability of highway guardrail nets using this kind of anti-corrosion treatment is good: The galvanized layer is metallurgically bonded with the steel and becomes part of the steel surface, so the durability of the coating is relatively reliable;
The coating of the guardrail net has strong durability: the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use; specific protection: every part of the plated part can be plated with zinc, even if It can be protected in detail in recesses, sharp corners and hidden places; hot-dip galvanizing of guardrail nets saves time and effort: the galvanizing process is more convenient than other coating construction methods, and can prevent the installation of the guardrail on the construction site. The time required to paint the picture above. The hot-dip galvanized surface is white and has a large amount of zinc, which is slightly more expensive. Generally speaking, the dipped galvanized ones are more colorful and have good anti-corrosion properties.
