This type of guardrail system helps minimize injuries and fatalities on roads all over the world. Our steel w-beam guardrails are flex beam guardrails and are the most common type of Armco barrier. This style of road safety barrier is commonly installed due to its durability and low cost.Semi-rigid guardrails such as this have been proven highly effective in reducing the severity of traffic accidents.Our w-beam guardrail is state-of-the-art highway safety barrier technology that is designed for maximum strength and durability. The steel construction allows for some give while still remaining strong.The road safety barrier undergoes surface treatment like zinc or PVC coating to prevent corrosion.
