Wabash Steel Flatbeds
More Flexibility. Longer Life.
With some of the highest floor ratings in the industry, this trailer design offers exceptional load flexibility. The main beam provides a stronger web-to-flange attachment for long-life performance, and potential corrosion is eliminated by welding the high-tensile steel at all flange-web joints. In addition, the “K”-type structural assembly reduces side bending and increases durability.
Less Maintenance. More Uptime.
The interlocking apitong floor system uses two grade-8 floor screws at each crossmember. This double-shear connection reduces racking and nailer damage, while the radius edges on the “C”-section siderail reduce winch strap wear. The steel rub rail with recessed grooves also protects conspicuity tape for longer-lasting performance.
Better Visibility.
The enhanced visibility lighting system includes three stop/tail/turn lamps and five dual-function side marker lights. These marker lights also serve as turn signals, improving motorist visibility and overall highway safety.
Superior Corrosion Resistance.
Every steel surface is 100% shot-blasted before priming and painting—eliminating the need for chemical pretreatments. From ultra high-zinc epoxy primer and galvanic coating to automotive-grade acrylic urethane paint, this trailer delivers unmatched corrosion resistance and higher resale value.
