metal road safety barriers for sale market

metal road safety barriers for sale adopts advanced technology and equipment to produce various specifications of guardrails. The products are widely used in municipal public works construction, highway, grid construction, municipal facilities, road and Bridge guardrails.

Guardrail board is an important traffic safety facility in the facilities along the expressway, which plays an important role in protecting the safety of drivers, passengers and vehicles. metal road safety barriers for sale is also an important part of expressway maintenance and repair.

The proportion of maintenance funds used in the daily maintenance and repair of expressway is often high. How to make full use of the limited maintenance funds and reduce the maintenance cost of the guardrail has always been the problem that every expressway operation and Management Department expects to solve.

and the application of the guardrail plastic renovation and reuse technology is a good choice to solve this problem. Next, we will mainly from the comparison of maintenance costs.

metal road safety barriers for sale explain the key points and necessity of promoting the application of plastic spraying technology for guardrail plate shaping. Because guardrail is a large-scale and long-term outdoor facility, different protection systems must be selected according to different atmospheric environment to carry out necessary metal anti-corrosion treatment.

At present, the protection of guardrail products is mainly divided into four categories: galvanizing, aluminizing, electrostatic spraying after galvanizing (aluminum), hot-dip after galvanizing (aluminum).

metal road safety barriers for sale in the area with less pollution, metal road safety barriers for sale can adopt separate hot-dip galvanizing layer protection or separate electrostatic spray protection. However, in coastal cities or heavy industrial areas, especially in the area with acid rain.

ordinary hot-dip galvanizing or electrostatic spray single coating guardrail plate may lose its effectiveness before metal road safety barriers for sale reaches the service life, resulting in a significant increase in the maintenance cost of guardrail plate.

metal road safety barriers for sale introduce

Although the corrosion resistance of hot-dip aluminized guardrail is better than that of ordinary hot-dip galvanizing guardrail, the cost comparison from its process, technology and environmental impact is far higher than the cost of hot-dip galvanizing treatment of guardrail.

so metal road safety barriers for sale should not be popularized. The single-layer protection of hot-dip galvanized (aluminum) guardrail can not be compared with the double-layer protection of hot-dip galvanized (aluminum) and electrostatic spray plastic (hot-dip plastic) guardrail in terms of service life.

applicable environment and decorative appearance. The thickness of the plastic layer of the guardrail treated by hot-dip galvanizing (aluminum) + plastic dipping is nearly twice as thick as that of hot-dip galvanizing (aluminum) + electrostatic spraying.

Although its corrosion resistance effect is better than that of hot-dip galvanizing (aluminum) + electrostatic spraying, its normal service life is not significantly longer than that of the latter, and its material and process cost is more than 20% higher than that of the latter.

metal road safety barriers for sale is also an uneconomical method to compare the guardrail protection system of hot-dip aluminizing + electrostatic spraying with that of hot-dip galvanizing + electrostatic spraying.

metal road safety barriers for sale protection system of hot-dip galvanizing + electrostatic spray molding can achieve good anticorrosion effect in most parts of the country, especially in heavily polluted or acid rain areas, and the service life of guardrail is greatly extended to more than 25 years.

so metal road safety barriers for sale is the current economic protection method. At present, compared with hot dip molding, electrostatic spray molding has been gradually popularized because of its low cost and simple technology.

metal road safety barriers for sale the other aspect of reducing the maintenance cost of guardrail is the shaping and recovery of waste guardrail.
