Our roadside barriers and guardrail components need to be fastened together so we need high quality guardrail fasteners such as nuts, bolts, and washers. We supply guardrail plate washers in a variety of sizes, including 76×44×4mm, 75×45×5mm, and 120×40×5mm. Made of high quality steel, these plate washers go through a hot-dip galvanizing process to improve their corrosion resistance. The purpose of a guardrail plate washer is three-fold: to reduce friction between the fastener and the fastened item, to prevent slipping, and to minimize stress.
