The highway guardrail is the main form of the semi-steel guardrail. It is a continuous structure in which the corrugated steel guard plates are spliced to each other and supported by the main columns. The role of vehicles in absorbing energy when they collide is neither easy to crash, but can also play a good role in protecting the vehicle and passengers.
The folding of the highway guardrail increases the aesthetics, and at the same time increases the strength of the fence, both of which are obtained; The automatic production line is extruded and formed, the surface is clean and free of damage, the corrosion resistance is extremely strong; the surface treatment is mature; antisepsis, anti-aging and anti-resistance Features such as drying, high temperature resistance, low temperature, etc. The service life in the outdoor environment can reach 10-25 years. The product structure is concise, beautiful and practical, easy to transport, installation, good anti-theft performance, limited by the actual terrain, for mountain, slope, and more The zone is particularly adaptable and affordable, suitable for large areas.
According to the surface treatment is divided into hot galvanized wave fence and galvanized spray two.
Locations can be divided into roadside guardrails and central divider guardrails.
According to the collision class can be divided into A and S grade. The S-class guardrail is of a reinforced type and is suitable for use on road sections that are particularly dangerous. Class A is used for special roads. Commonly used road side wave beam guardrail can be divided into B, A, SB, SA, SS five levels according to collision avoidance grade.
It is mainly used for the construction of safety and anti-collision projects such as highways, large-scale parking lots, scenic spots, high-speed, provincial roads, and rural roads.
