Guardrail is a safety system for people or vehicles made of long material as a fence on dangerous road such as highways, mountains, rivers, ravines, etc. Its function is as a protector so that vehicles passing through it are protected from falling into rivers or ravines.
Guardrail is made of steel which is formed by cold-rill machine so as to produce a quality steel beam called W-beam. The nature of Guardrail is anti-rust so it will not be affected at all with extreme weather outside the room because it has been coated with a rust coating (galvanized layer) and until now the foam is said to be safest to use as a Guardrail.
