Guardrail is an impact absorber of more flexibility compared to concrete blocks. Their use is a necessity at the roadsides leading to mountains or valleys. On roads where reverse traffic lines are next to each other, guardrails are used for separation. Guardrails, concrete blocks, metal blocks or cable absorbers must be clearly considered to be used for the right application.
The body of guardrail is composed of 3mm thickness metal sheets of ST37 type. These are coated after forming using three different methods of hot galvanized (65 to 90 microns), cold galvanized (around 20 microns) or electrostatic (around 75 microns). Weight of each guardrail unit is 49 + 1.5Kg.
