Highway guardrail is the main form of semi-rigid guardrail, which is a continuous structure that is spliced with corrugated steel guardrail panels and supported by main columns. The effect of the vehicle on absorbing energy when it collides is not easy to be crashed, and at the same time it can play a very good role in protecting the vehicle and the driver and passengers.
The bending of expressway guardrails can increase the aesthetics and increase the strength of the guardrails at the same time; it is extruded by an automatic production line, the surface is clean and damage-free, and it has strong anti-corrosion properties; the surface treatment method is mature; anti-corrosion, anti-aging, anti-corrosion Sunshine, high temperature resistance, low temperature and other characteristics, the service life in the outdoor environment can reach 10-25 years; the product structure is concise, beautiful and practical, easy to transport and install, good anti-theft performance, limited by the actual terrain, suitable for mountains, slopes, and many bends The zone is extremely adaptable, the cost is moderate, and it is suitable for large-scale adoption.
What are the classifications of highway guardrails?
According to the surface treatment, it is divided into two types: hot-dip galvanized corrugated guardrail and galvanized spray-coated.
Galvanized spray highway wave guardrail
According to the setting location, it can be divided into roadside guardrails and central divider guardrails.
According to the anti-collision level, it can be divided into A level and S level. The S-level guardrail is a reinforced type, which is suitable for use on particularly dangerous road sections on the roadside, and the A-level guardrail is used for special roads. Commonly used roadside wave beam guardrails can be divided into five levels: B, A, SB, SA, and SS according to the anti-collision level.
