Guardrail beam plays a crucial protective role in highway guardrails

The guardrail beam in the highway guardrail is its main component, playing a crucial protective role. The guardrail beam is usually composed of soil foundations, pillars, beams, and endurance boards, which work together to absorb collision energy and guide out of control vehicles to change direction, preventing them from rushing out of the road.

Structurally, the waveform steel plates of the guardrail beam are spliced together and supported by pillars, forming a continuous structure. This design not only gives the guardrail a strong ability to absorb collision energy, but also effectively guides the line of sight, making it coordinated with the road alignment.

In order to further improve its anti-corrosion performance and service life, guardrail beam is usually hot-dip galvanized. This treatment allows the guardrail to maintain its protective performance in harsh environments such as outdoor, low temperature, and acid rain, with a service life of up to 30 years.
