DACHU has a large selection of highway Thrie Beam Highway Guardrails including Galvanized Steel Posts, Flared Ends and Hardware.
DACHU guardrail is manufactured to AASHTO specifications in M180 Class A or B, and finish types 1, 2, 3, or 4.
Every piece of DACHU Thrie-Beam guardrail is stamped with a brand registration that is repeated throughout the entire length of the rail.
We have standard highway guarding products and can also provide custom fabrications on a make-to-order basis, with or without galvanized coating.
