The improved Hyundai Translead HT ThermoTech refrigerated trailers are among the most durable, thermally efficient, and lightweight trailers on the road, according to the company. Hyundai Translead has focused on how to work in compliance with new regulations to maintain temperature efficiency and has taken steps to address longevity by redesigning the components of the trailer most susceptible to damage. The deck now uses taller, stiffer structures to support the floor surface. Heavy duty aluminum floor extrusions fit together with a mechanical lock to take stress off the welded joints, and the new fully automated welding fixture lays down a weld-bead of greater mass for additional strength. All Hyundai Translead products use the corrosion protection from hot-dipped galvanization of steel assemblies.
