Horsebox Underseal & Chassis Repair
Horseboxes take constant damp from bedding, washing out and standing in yards — and the chassis carries live weight, so corrosion there is a safety issue, not a cosmetic one.

Common Horsebox rust hotspots we treat
Years on Irish roads, salt and damp wear down even the toughest Horsebox chassis. These are the areas we strip, weld and re-seal every week.
- Chassis rails and crossmembers under the floor
- Floor bearers and floor edges
- Ramp hinges, springs and ramp frame
- Wheel arches and mudguard mounts
- Partition and tie-ring mounting points
- Drawbar and coupling area on trailer boxes
