Highway Safety Overview
Southern Guardrail is committed to providing high quality guardrail and safety components designed to reduce highway fatalities. From wood barrier construction to rail mounting hardware, all products have been monitored and tested for use in state and non-state highway projects.
Galvanized & Wooden Guardrails
Guard rails are something most people don't think about until it saves their lives. Annually, over 6,840,000 people in the U.S. are involved in roadway accidents resulting in 3,511,000 injuries and 41,907 fatalities (source: Federal Highway Administration). Guardrails play a major role in saving the lives of people involved in many of those accidents.
Galvanized guardrails are constructed from high-strength 12-gauge (Class A) and 10-gauge (Class B) galvanized steel for effective impact absorption. The most common highway guardrail is the galvanized W-Beam, which are longitudinal highway barriers designed to reduce the severity of run-off-road (ROR) collisions.
Roll-formed into the shape of a “W” to typical catch car bumpers, W-beam guardrails have proven an effective and economical solution to roadside safety. Every component of W-beam guardrails, from the mounting hard to the wooden blockouts, has been subjected to numerous full-scale crash tests to determine the optimal construction method for reducing injuries.

Rail end treatments provide effective deflection and absorption of oncoming traffic without spearing. Rail end treatments are available in a wide variety of end types, including flared end, question mark ends, ET2000, ET-Plus, XRT-350, SKT-350, and Regent-C.

Steel, Wooden & Rubber Highway Posts
State and Federal highway posts regulations have recently been updated after a NCHRP 350 report determined that wooden posts provide increased safety over steel posts.
The National Crash Analysis Center (NCAC) has made great strides in determining the safest guardrail post for highway use. The NCAC developed computerized crash simulation finite element (FE) models that which was used in combination with traditional crash testing to determine the optimal post for highway use.
Finite elements recreated the explicit geometry, weight, inertia, and mass of each guardrail component. Comparisons to full-scale crash tests have validated the accuracy of finite element models. These tests helped determine the optimal choice of blockouts, steel gauge, and post gaps for optimal guardrail performance.
