4. Steel Highway Guardrail Principle 

a. The wave-shaped steel highway guardrail is a series of corrugated steel fence panels attached to each other by stitching to a continuous post for support along the whole structure.

 

b. Using the soil base, guardrail posts and guardrail beams deformation, the guardrail system absorbs impact energy forcing out of control vehicles to alter their velocity. This prevents the vehicle from running off the road to protect the vehicle itself and passengers to reduce losses caused by the accident.

 

 

c. Waveform phase and flexible steel beam guardrails have the great ability to absorb kinetic energies and is aesthetically pleasing as it can be aligned along the contours of the road. It can also be used in a small radius curve.

 5. Steel Highway Guardrail Application

 

a. To provide steel highway guardrail protection for motor vehicles against dangerous road areas such as steep slopes, high embankments, obscure curves/bends and sharp corners.

b. To absorb the kinetic energies from sudden impact collisions to minimize damage to the vehicle and injury to the passenger.

c. To act as a directional steel highway guardrail for drivers to be aware of the correct driving direction.

d. To act as a median barrier to avoid head-on collision.

 

6. Steel Highway Guardrail Advantages 

a. Can ensure minimum damage to the vehicle and its occupants.

b.Repairs are quick ensuring that complete road safety is maintained along the entire length of guardrail.

c. Can prevent 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

d. All components are galvanized as a countermeasure against the elements for a longer service life.

e. Ideal replacement for traditional metal Roadway Guardrails.

f. OEM or ODM service offered

g. Precision machining and Extensive exporting experience
