The decking used on this trailer is 5mm alloy treadplate - click here for other decking options. Plywood or timber can be used down the centre of the trailer to close up the opening between the wheel wells.
If using 3mm steel treadplate, use the same bending profile as below. 3mm alloy treadplate is too thin to be used as decking material by itself. It can be used if timber or plywood (17mm or thicker) is fitted underneath.
Cut and fold the deck cladding as below, removing all sharp edges and profiling the leading edge to help prevent potential puncture points.
The cladding can be fastened to the chassis with suitably sized rivets, self tapping metal screws or coach bolts.
