WE PRODUCE THREE TYPES OF CONSTRUCTION TRAILERS WHICH ARE AS FOLLOWS: Construction Dumper trailers with a scow tail, Construction Monocoque trailers which have a flat floor and the Construction PRO trailers with a Hardox® body. Please get in touch for more information. WHAT IS HARDOX®? Hardox® is a wear plate; structures made of Hardox® weigh less and last longer than those made from mild steel. A tipper body made from Hardox® is more durable due to the unique combination of hardness and toughness. Using Hardox® allows for a body design with a minimum number of reinforcing beams on the outside.
