Highway Guardrail
Guardrail beams we supply are 10 gauge and 12 gauge materials, which process is going through flattening, punching, galvanizing or plastic coating, fabricating and shearing process.
Highway guardrails are considered a passive barrier and are widely installed to keep vehicles within the roadway. When an unavoidable collision occurs, highway guardrail effectively reduces the speed of the offending vehicle and redirects it back onto the roadway by controlling the exit angle. In addition, it makes the highway visible to avoid running animals from straying into the roadway.
We supply and manufacture beam guardrails in accordance with China National Standard JT/T281-1995(Corrugated Sheet Steel Beams For Expressway Guardrail - China), AASHTO M-180(Corrugated Sheet Steel Beams For Highway Guardrail - USA), RAL-RG620 (German) or any other International Standards. The base steel we use meets Steel Grade Q235B (equivalent to S235JR according to DIN EN 10025 and Gr. D according to ASTM A283M) or Q345 (S355JR / ASTM A529M 1994).
