Product description

The Powder Coated Guardrail plate is the main structure of the semi-rigid guardrail, which is an uninterrupted shape composed of corrugated metal guardrail plates, connected and supported by the post.

Powder Coated Guardrail uses the deformation of the foundation, post and beam to absorb the force of the collision and control the pressure generated by the vehicle, so that Powder Coated Guardrail can change the direction and return the vehicle to the normal direction of travel, protect the vehicle and passengers, and reduce the loss caused by accidents.

Why are there black spots on the guardrail?

Sometimes you will hear customers say that the newly bought waveform guardrail does not take long, the surface

appears black spots, black piece by piece, this situation is a very serious quality problem. This is because the corrugated

guardrail plate is not passivated, the appearance is not visible at the beginning, after a period of time, especially after

the corrugated guardrail plate is exposed to the sun or rain, this will happen, and then it will quickly rust.

This situation is not uncommon, it may be that the quality of the passivation liquid used by the supplier to save costs is not

good or the passivation liquid is put less, the passivation time is short, there are some manufacturers, the production 

qualification is insufficient, the production experience is less, it is also possible to happen.
