Double Tees are a time-proven product that are a favorite among parking structure designers. Because of their ability to provide long, clear spans, they are an excellent choice for economical and dependable floor and roof systems. Gymnasiums, natatoriums and manufacturing plants benefit alike from the open spaces that Double Tees provide. Double Tees are produced in standard widths of 8 foot or 12 foot. Narrow pieces can be custom produced, if required.
