We set a new standard for guardrails.
An improved guardrail that compensates for driver frustration and fatigue that has accumulated due to the closed section (2W, 3W), which is a disadvantage in existing guardrails and allows drivers to enjoy the scenery and drive safely thanks to D-beam-shaped rails.
closed guardrail
open guardrail
It is suitable as a protective rail for scenic areas, such as riversides and coastal roads because it maintains the view.
Compensates for driver frustration and fatigue
In case of a minor accident, parts are easily replaceable and maintained
Vehicle collisions can be prevented by minimizing icing by installing open rails that allow abundant sunlight
Depending on the installation location, painting is possible, and its aesthetics blends well with the surrounding environment.
It minimizes environmental pollution by reducing the amount of calcium chloride used in winter by allowing more sunlight through
The rail has fluidity
Sliding occurs
The direction of motion changes
Protects passengers, restores the vehicle direction, and maintains vehicle speed
Maintains rigidity + Forms the moving impact-absorbing resistance points
Controls the performance between contrasting elements of the rigid and soft structure + ductile structure
Induces multi-stage crash
Part that deformed upon crashing Has points designed to crumple from impact
Induces deformation to the points vulnerable to impact
Stepped structure A structure with a protruding upper part
Forms a stumbling block because of the external deformation of a vehicle

PosMAC, a ternary alloy coated steel sheet produced by POSCO, is used.
It has corrosion resistance five to ten times higher than that of hot-dip galvanized steel sheet.
