Product Features

1) Dual Strength (DS) rails have been modified to enable protection for the large and small vehicles while minimizing the possibility of crossing over and enhancing the impact absorbing capability.
- Differentiated steel structure as upper beam (4.8T) designed for the large vehicles strongly upholds to prevent overcoming and shares the lower beam (2.5T, 3.0T) for the small vehicles absorb impact
- Dual Strength Thrie-beam section designing ensure the continuity of structure with existed one's as well as reduced its weights as replaceable lower beams only in case of slight accident, make easy the guardrails installation on the site leads to produce up to 5m length. This is the advantage point of DS guardrails in economic perspective and maintenance improvement.

2) The synthetic post made of the pipe with steel reinforced concrete is to prevent the local bending, greatly increase torsion stiffness by composite action.
- Post reinforced concrete materials doubles the peak load and stiffness as well as depresses sudden breakage of plasticity when opposed to the entry of the vehicle lane crash deformation due to excessive blocking caused two car accidents and increase the intensity of the flexible guardrails.

3) Joint fixture with V-notch
- V notch partial destruction of a small car crash that will absorb the impact force by induction.
- Prevents crossing over by resisting the inclination of beam sections.
- This structure was developed to increase availability in the vertical stiffener and the bottom flange formed by bending in the vertical direction.
