W-Beam and Thrie-Beam Guardrail Made to Your Specification
W-beam and thrie-beam guardrails are produced to AASHTO M180, the standard written into road authority tenders across the Americas. The factory rolls the profile from Tang Steel coil and hot-dip galvanizes it in-house to 550 g/m2. Standard W-beam is 4128 x 310 x 83 mm at 2.67 mm thickness. Thrie-beam has three corrugations and is used where higher impact resistance is required. Both are supplied with posts, terminals, and fittings from the same production run.
