Steel Drop Decks
Our rugged steel drop deck trailer is built to last. Heat-treated 130 ksi steel provides increased strength and low trailer weight. In addition, the premium paint process ensures best-in-class corrosion resistance and your trailer looking good year after year.
Greater Load Flexibility. Longer Useful Life.
With some of the highest floor ratings in the industry, this trailer design offers load flexibility. The main beam comes standard with a limited lifetime warranty and provides a stronger web to flange attachment for long-life performance. Potential corrosion is eliminated between the flange and web by welding the high tensile steel at all flange-web joints. In addition, the P-spindle wheel ends provide longer wheel end life.
Lower Maintenance. Increased Uptime.
The interlocking apitong floor system connects using two grade-8 floor screws at each crossmember. The double shear connection reduces racking and damage to nailers around the screw holes. In addition, the radius edges on the “C” section siderail reduce the wear of winch straps, while the steel rubrail with recessed grooves, protect conspicuity tape. Designed to lower maintenance costs, this steel trailer reduces down time, keeping you on the road.
The standard enhanced visibility lighting system offers three stop/tail/turn lights and five dual-function side marker lights. The side marker lights also function as turn signals for improved visibility to motorists.
Premium Paint. Superior Corrosion Resistance.
100% of steel surfaces are shot blasted prior to applying primer and paint, eliminating the need for chemical pretreatments. From the ultra high-zinc, epoxy primer and galvanic coating, to the automotive grade Valspar® acrylic urethane paint, this trailer is made to resist corrosion and increase re-sale value.
