Trailer Underseal & Chassis Repair
Horseboxes, plant trailers and tipping trailers take a beating from mud, muck spreaders and standing water — and a weak chassis is a safety issue, not just a cosmetic one. Rayco weld and underseal trailer chassis to keep them roadworthy and rust-free for years.
Common Trailer rust hotspots we treat
Years on Irish roads, salt and damp wear down even the toughest Trailer chassis. These are the areas we strip, weld and re-seal every week.
- Main chassis rails and drawbar
- Axle stands and suspension mounts
- Ramp hinges and floor cross-members
- Wheel arches and mudguard mounts
- Coupling and jockey wheel brackets
- Tipping rams and pivot points
