Corrugated steel guardrails are the most widely used road safety protection system on motorways and municipal and county roads. W-beam Highway Guardrail absorb the kinetic energy generated by vehicle impacts through the compression and bending of their cross-beam steel plates, thereby preventing the dangers posed by vehicles losing control and crashing off viaducts or cliffs. They also prevent vehicles from crossing the central reservation and colliding with oncoming traffic, thus avoiding major chain-reaction accidents. Consequently, guardrails are the most essential safety feature on motorways.
The reasons for installing corrugated guardrails on motorways are as follows:
1. Corrugated guardrails are installed in the centre of the carriageway; in the event of a vehicle collision, they effectively prevent vehicles from crossing into oncoming traffic, thereby avoiding major chain-reaction accidents.
2. Corrugated guardrails are semi-rigid protective structures with excellent ductility and superior kinetic energy absorption capabilities. Upon impact, they can deflect appropriately, forcing the vehicle back onto its normal trajectory.
3. Corrugated guardrails mitigate the harm caused to drivers by collisions. Their high ductility and resistance to breaking allow them to deform upon impact, bringing the vehicle to a halt. This excellent cushioning effect reduces the severity of accidents.
4. Corrugated guardrails also prevent traffic accidents caused by pedestrians or wildlife crossing the road indiscriminately from either side;
Compared to concrete barriers and common steel pipe barriers, corrugated barriers offer greater resilience. Although they may sustain localised damage following a collision, the costs of repair and replacement are relatively low. Consequently, corrugated barriers are particularly well-suited for large-scale installation on motorways.
