Bonanza Trailers are designed to be heavy duty, with long term durability engineered into every trailer.

A solid steel construction with high quality full hot dipped galvanised coating prevents corrosion, ensuring long life and a rust-free finish for the long haul.

Folded metal sides and a flooring construction utilising centre joints with strong box section reinforcement increases the strength and durability of every Bonanza Trailer, ensuring a long, trouble-free life from every trailer we build.
