How can the highway guardrail be used for a longer time in outdoor use? The highway guardrail is widely used today, but the anti-corrosion of the guardrail has always been a matter of concern. Recently, hot galvanizing of the highway guardrail has been studied, which can not only ensure the quality, but also increase the service life. The triangular bent protective fence net has been widely used in the embellishment and protection of expressways, highways, railways, airports, factories, residential quarters, ports and docks, municipal oases, garden flower beds and oases. Guardrail net is a kind of connection to establish a net and become a progressive guardrail product. It is mainly divided into three categories: galvanized, plastic sprayed and plastic soaked. The product is welded with high-quality low-carbon steel wire. The corrosion conditions include electroplating, hot electroplating, plastic spraying and plastic dipping. The products are beautiful, generous, consolidated and corroded. It is specialized in railways, highways and waste landfills. It has the characteristics of being used, beautiful, broad vision and outstanding maintenance function.
Guardrail is a product of professional protection, which has the characteristics of classics, beauty and broad vision, and has outstanding maintenance function. The concrete pouring is a pillar of the net body. Generally speaking, the project cost is low. With high strength and overall stability, the plastic layer of net body color has excellent corrosion resistance and embellishment, making the net tail ring concrete, harmonious and beautiful. Product features: anti-corrosion, anti-aging, weather resistance, sun resistance, etc. The anti-corrosion coating, including hot plating, plastic spraying and plastic dipping, is mainly used for another barrier on the closed railway expressway, and the development zone is used at the gate. This product is mainly used as the barrier and maintenance at both ends of the railway. It is a product of railway closed barrier in railway professional occasions. It has the characteristics of classics, beauty, vision and openness, and has outstanding maintenance function. All railway barriers are constructed by concrete pouring, which is safe, with clean columns, low project cost and overall safety. With high strength and overall stability, the plastic layer of net body color has excellent corrosion resistance and embellishment, making the net tail ring concrete, harmonious and beautiful.
When installing the guardrail, the construction unit shall accurately grasp various construction drawings, and the accurate orientation of various pipelines buried in the subgrade is not allowed to cause any damage to underground equipment during the construction process. If the column of the railway guardrail is driven too deep, the column shall not be pulled out for correction, and its foundation shall be rammed from the beginning, or the column orientation shall be adjusted. When approaching the depth during construction, attention shall be paid to controlling the hammering force. The railway guardrail should be equipped with flange plate, and pay attention to the positioning of the flange plate of the guardrail and the control of the top elevation of the column. Guardrail is a safety equipment and installation project of railway and an important part of Expressway appearance quality. The connotation quality of railway guardrail lies in the raw materials and processing process, and its appearance quality depends on the construction process. During construction, we should pay attention to the combination of construction preparation and pile driver, constantly summarize experience and strengthen construction management, so as to ensure the quality of the device. Highway guardrail net products have bright colors, beautiful shapes, environmental protection, super erosion resistance, salt fog resistance, temperature and heat resistance, weather resistance, gorgeous colors, high strength, long service life and low maintenance and repair cost.
On the cost of hot-dip galvanizing treatment of highway guardrail: the cost of hot-dip galvanizing and rust prevention is lower than that of other paint coatings; Durability of highway guardrail: in suburban environment, the standard thickness of hot-dip galvanizing and rust prevention can be maintained for more than 50 years without repair; The antirust layer can be repaired in the urban area or offshore area for 20 years; The highway guardrail adopts this kind of anti-corrosion treatment, which has good reliability: the zinc coating is metallurgically connected with the steel and becomes a part of the steel appearance, so the durability of the coating is relatively reliable;
The coating of guardrail has strong resistance: the galvanized layer forms a special metallurgical layout, which can accept mechanical damage during transportation and use; Specific maintenance: every part of the plated parts can be plated with zinc, and can be specifically maintained even in depressions, sharp corners and hidden places; The hot-dip galvanizing of guardrail net saves time and labor: the galvanizing process is more convenient than the construction method of other coatings, and can prevent the required work from being painted on the site after the installation
