image 11: Steel pan stairs.
These images 11-13 show steel pan stairs being installed between floors. The stair is fabricated out of channel sections, angle sections, and cold formed sheet steel. The stairs will receive a concrete fill and are fabricated after the floor to floor heights have been field verified. The stairs shown are fire stairs, which will be contained in a two hour rated gypsum board and steel stud assembly. Note that both hanger steel rods and short hollow steel tube sections are used to support intermediate platforms.
