No additional support is necessary when using Dura Trac Clearspan flooring. The Clearspan style is manufactured to be completely self-supported. The expanded metal or woven wire is welded onto the frame prior to applying the plastisol coating, therefore no steel is exposed on the finished product.
Dura Trac Original calf floors are made to use with existing support frames. For this reason, Dura Trac Original calf floors not only work great for new buildings but also for replacement flooring in your existing buildings. As with all our floors, the Original style is 100% plastisol coated so there is no exposed steel. *Proper support for the Original Calf flooring is extremely important. Supports must run laterally across the short way of the openings. The minimum requirement for support under calf floors is 14 inches apart.
