The Principle and Classification of Expressway Guardrail The Principle and Classification of Expressway Guardrail

The expressway guardrail is the main form of the semi-steel guardrail. It is a continuous structure in which corrugated steel guardrails are spliced to each other and supported by the main column. The effect of the vehicle on absorbing energy during its collision is not easy to be destroyed, and it can also protect the vehicle and the passengers.

The bend of the expressway guardrail increases the aesthetics and increases the strength of the fence. The expressway guardrail is extruded from an automatic production line, and the surface is clean and undamaged, and the corrosion resistance is extremely strong. Its surface treatment is mature. It has the characteristics of anti-corrosion, anti-aging, anti-sun. It is resistant to high and low temperatures. Its service life in outdoor environment can reach 10-25 years. The product structure is concise, beautiful and practical, easy to transport, install, and has good anti-theft performance. It is limited by the actual terrain and is highly adaptable to mountains, slopes and curved areas. It is cost-effective and suitable for large-scale use.

Expressway guardrail classification

According to the surface treatment, it is divided into two types: hot-dip galvanized wave guardrail and galvanized spray.

The principle of expressway guardrail

1.The expressway guardrail is the main form of the semi-steel guardrail. It is a continuous structure in which corrugated steel guardrails are spliced to each other and supported by columns.

2.It uses the deformation of soil foundation, column and beam to absorb the collision energy, and forces the out-of-control vehicle to change direction and return to the normal driving direction to prevent the vehicle from rushing out of the road to protect the vehicle and passengers and reduce the losses caused by the accident.

3. The corrugated beam guardrail is soft and phase-strength, has strong ability to absorb collision energy, has a good line of sight induction function, can be coordinated with the road line shape, has a beautiful appearance, can be used on a small radius curve, and the damage is easy to replace.
