Thrie-Beam Steel Guardrail is a type of guardrail that is essentially two pieces of W-Beam Guardrail formed into one single shape. It is used in specific circumstances where additional coverage may be necessary. Certain States prefer this product for highway use, and it can frequently be seen at racetracks where lower vehicles could interact with the guardrail posts.
