Hot dipped galvanized guardrails are durable system that
can provide long time protection to the highway
vehicles. The complete system is usually composed with
beams (w beam or thrie beams), galvanized posts and hot dipped
terminal ends. The anti-collision safety grades are:
A/B/SA/SB/SS.
Popular size SciSe exports:
Corrugated steel plate beams: Two-wave profile:
4320mm×310mm×85mm×3/4mm; Three-wave profile:
4320mm×506mm×85mm×3/4mm
Matching posts for two-wave: 114/140mm×4.5mm
Upright posts for three-wave: 130mm×6mm, 140mm×4.5mm
Anti-collision grade: A/B/SA/SB/SS
Applied Standards for Manufacture and Quality
Control: 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.
Hot dipped galvanized steel guardrails are
considered the effective safety barriers for highway, expressway
and bridges. With thick zinc coating surface, the galvanized w
beams or thrie beams offer excellent corrosion resistance and
rust resistance property. The long service life it offers renders
the cost for the high standard galvanizing.

System Advantages
- The barriers ensure minimum damage to the vehicle and its
occupants.
- During collision, the beam absorbs maximum energy by flattening
out laterally and restrains the vehicle from veering over.
- Prevents the vehicle from skidding back onto the carriageway by
controlling exit angles through gradual deceleration and
effective redirection of the vehicle back on to the road.
- Enables quick repairs in case of accidents.
- All components are galvanized for longer life.
