The OTR Concrete Deck is well suited for resisting corrosion and rust, and generally requires less maintenance than steel decks, helping to extend the life of the scale. A concrete surface also yields better traction in wet and icy conditions. Because of their design, concrete decks distribute the load over a wider area than steel decks. Concrete decks are poured at the job site and typically have a cure strength of 4,000 PSI at 28 days. The concrete is reinforced with steel rods and a minimum of two wide-flange main beams and seven wide-flange beams below.
