Highway Guardrail Panel Installation Requirements and Precautions

Guarantee that the overlapping direction of each guardrail panel is consistent with the traffic direction on the road.

When securing guardrail panels to the anti-rebound blocks on brackets previously mounted on posts with connecting bolts, it is recommended by the guardrail manufacturer not to overtighten the bolts prematurely, as this makes it difficult to make changes and adjustments later.

Check for smooth linearity and consistent elevation. Note: The elongated holes on the corrugated plate serve for timely adjustment.

◆When the guardrail line is smooth and even, tighten the connecting bolts and splicing bolts on the guardrail panels.

The installed wavy panels should be linear and smooth, the high-speed guardrail panels installed should be uniform in color, flat and glossy, with no damage.

Highway guardrail panels are semi-steel protective products, with the corrugated guardrail panels made from Q235 low-carbon steel plates. The surface is treated with hot-dip galvanizing and spray painting to prevent corrosion and rust. When installing the guardrail panels, the spacing between the posts is typically 4 meters, and the length of the corrugated panels is usually 4.32 meters, slightly longer due to the need for end connections. Since the length of the guardrail panels is fixed, the number of panels required can be calculated by measuring the length of the road where the panels need to be installed. For a 100-meter stretch, you will need 250 panels.

Therefore, the correct installation of road guardrails is very strict. As manufacturers of road guardrail panels, guardrails are a safety assurance for people driving on the road, thus playing a significant role in people's lives. Installation requirements for highway guardrail panels: The manufacturing process of highway guardrail mesh involves weaving and welding, featuring corrosion resistance, aging resistance, sun protection, and weather resistance. The corrosion protection methods on the surface of the guardrail mesh include electroplating, hot-dipping, powder coating, dipping, and galvanized dipping.

What are the requirements during the installation of road guardrails? Answer: The specifications and dimensions of highway pillars are mainly controlled between Φ114～Φ140mm, and can be measured according to the following sizes:
