Highway Barrier

Highway guardrails, also known as crash barriers or safety barriers, are essential components of road infrastructure designed to enhance traffic safety. Here is a brief description: 1.Purpose: 1.1Safety: Guardrails are primarily installed to prevent vehicles from leaving the roadway, reducing the risk of accidents and mitigating the severity of collisions. 1.2Guidance: They help guide drivers back onto the road after minor departures. Protection: Guardrails protect vehicles and their occupants by absorbing impact energy during crashes. 2.Types: 2.1Beam Guardrails: The most common type, consisting of longitudinal beams mounted on posts. These can be further categorized into: 2.1.1W-Beam Guardrails: Named for their W-shaped cross section, commonly used in rural areas. 2.1.2Thrie-Beam Guardrails: Featuring three beams connected by bolts, often used in urban areas for greater flexibility and containment. 2.2Cable Guardrails: Made of multiple steel cables stretched between posts, typically used on steeper terrains or where visibility is crucial. 2.3Box Beam Guardrails: Comprising box-shaped beams, offering higher containment and strength.
