Core Technology
ROADEX's core technology is a single-bolt fastening structure with a nut embedded in the base of the post. It replaces the conventional three-anchor method, cuts installation time, and lets a damaged post be swapped in minutes without re-drilling — while a shock-dispersing dual structure and high-visibility two-tone design raise durability and recognition.
One bolt instead of three anchor bolts. The nut is moulded into the base, so installation needs a single core hole.
A damaged post is unscrewed from the embedded nut and a new one is screwed in — no re-drilling, no new epoxy.
Designed for repeated vehicle impacts: less tearing and pull-out, longer service life. Recycled TPU material.
Two-tone colours and high-intensity reflective sheeting improve recognition; region-specific colours improve the streetscape.
