Thrie-Beam Guardrail. While most Gregory guardrail is supplied in galvanized finish, it is also available in black, painted epoxy coatings, or weathered steel as alternative finishes for aesthetic applications. Gregory Thrie-Beam guardrail is manufactured to AASHTO specifications in M180 Class A or B, and finish types 1, 2, 3, or 4.
Hot dipped galvanized steel guardrails are considered the effective safety barriers for highway, expressway and bridges. With thick zinc coating surface, the galvanized w beams or thrie beams offer excellent corrosion resistance and rust resistance property. The long service life it offers renders the cost for the high standard galvanizing.
