We all knows that the highway guardrail board is a semi-steel protection product, and its corrugated guardrail board is made of high-quality Q235 low-carbon steel plate. The surface is treated with anti-corrosion and anti-rust treatment through hot-dip galvanizing and plastic spraying. When installing the guardrail, the distance between the guardrail posts is generally 4 meters, and the length of the corrugated guardrail is generally 4.32 meters, because the two ends of the guardrail need to be fixed and spliced, so the length of the guardrail is slightly longer. The length of the guardrail is fixed, so by measuring the length of the road where the guardrail needs to be installed, the number of sets of guardrails can be calculated. 100 meters need 250 sets of guardrails.

       The choice of the material of the guardrail plate column is also very important. Generally, the diameter of the column steel pipe is 114 mm and 140 mm, and the length can be customized according to requirements.

       The parts of the guardrail board are equally important. The guardrail board bolts, ends, rain caps and other parts also need to be hot-dip galvanized. If the anti-corrosion treatment is improper, a certain part will corrode, which will directly lead to the overall protective effect of the guardrail board. 

       Wave guardrails are mainly divided into two-wave guardrails, three-wave guardrails, and two-wave three-wave transition guardrails. Their main differences are mainly in protection effect, protection area and firmness, and they are used on different road sections. The three-wave guardrail board is good in terms of comprehensive parameters. It is mostly used in dangerous sections such as bridges. The two-wave three-wave transition board is used for the transition between the two-wave board and the three-wave board by looking at the name. The two-wave guardrail board is widely used. Applicable to all road sections.

 

　   The composition of the wave guardrail board: column, column cap, bolt, guardrail board, end, anti-blocking block, bracket, etc. These components are indispensable, and are an important part of the guardrail.
