When installing the corrugated guardrail, first install the bracket on the column, do not tighten the fixing bolts too much, and then use the connecting bolts to fix the guardrail on the bracket. The guardrail and the plate are spliced with each other with splicing bolts. If the splicing is opposite, Even a minor collision can cause significant damage.

Wave guardrail

There are currently two types of guardrails: galvanized and plastic-coated. Compared with ordinary steel, the galvanized layer has lower hardness and is susceptible to mechanical damage. Therefore, be careful during construction and handle it with care. After the galvanized layer is damaged, Refill with high-concentration zinc within 24 hours and replace if necessary.

The anti-collision guardrail should be continuously adjusted during the installation process. Therefore, the connecting bolts and splicing bolts should not be tightened prematurely. The oblong hole on the guardrail should be used to adjust the line shape in time to make the line shape smooth and avoid local unevenness. When satisfied, then tighten all the bolts. According to experience, it is most qualified to install guardrails in groups of 3, 5, and 7 people, and it is easier to install when the installation direction is opposite to the driving direction.
