Consider double tees for those longer spans and heavier loads that exceed the capacity of hollowcore plank. Double tees have evolved from 1220mm (4'-0') widths to 2440mm (8'-0'), 3000mm (10'-0') and 3660mm (12'-0'). Depths can vary from 300mm to 900mm. Spans can range from 10 to 25m for floor loads to over 33m for roofs. Double tee dimensions are based on many factors (design efficiency, most popular usage, fire regulations, transportation regulations).
