Our steel flats are built strong and light. In fact, our tare weight on all our steel decks rivals aluminum / steel combo flats of the same spec. Offering an all steel platform offers incredible strength that is ready to work in the harshest of conditions. To protect your investment, we coat the steel outside with a 100% cold galvanization / zinc spray to combat corrosion. As always, part of our paint process ensures our trailers enter a large curing oven to ensure the perfect adhesion and paint properties when it leaves our production facility, enabling us to give you a finished paint product that is unmatched in the industry.
