The first is to select the finished wire drawn from the wire rod; for welding or weaving, this mainly depends on the skill and operating ability of the technicians and the production machinery. A good mesh is one where every welding or weaving point can be easily For good connections and frame materials, high-quality angle steel and round steel should be used. The angle steel and round steel selected for different guardrail net uses should also be different. In terms of the overall plastic spraying, attention should be paid to the uniformity of the plastic spraying, and Even the quality of the paint is crucial.
Purpose:
Mainly used for protective belts on both sides of highways, railways, and bridges; security protection at airports, ports, and docks; isolation and protection of parks, lawns, zoos, pools, lakes, roads, and residential areas in municipal construction.
     advantage:
1. The columns are made of concrete castings, so the project cost is low.
2. High strength and good overall stability.
3. The colored plastic layer has good corrosion resistance and decorative effect.
4. The overall fence is harmonious and beautiful.
5. Railway closures, highway guardrails, development zone boundaries, and field fences.
6. Anti-corrosion, anti-aging, anti-sun protection and other characteristics.

Issues that should be paid attention to when constructing railway guardrail nets
1. When installing, the construction unit should accurately grasp various construction drawings. Regarding the accurate locations of various pipelines buried in the roadbed, no damage to underground facilities is allowed during the construction process.
2. If the column is driven too deep, the column must not be pulled out for correction. The foundation must be re-consolidated before driving in, or the position of the column must be adjusted. When approaching depth during construction, attention should be paid to controlling the hammering intensity. Flanges should be installed on railway guardrails, and attention should be paid to the positioning of the flanges and the control of the top elevation of the columns.
3. The railway guardrail network is a safety facility installation project for the railway and an important part of the appearance quality of the highway. The inherent 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, attention should be paid to the combination of construction preparation and pile driver, continuous summarization of experience, and strengthening of construction management to ensure the installation quality.
