What type of fire rating can be achieved with Castcon stairs?
A. We generally pour our stairs eight inches thick, which achieves a four-hour fire rating. We can pour our stairs six inches thick, which will achieve a two-hour fire rating. Our stairs can be poured up to ten or 11 inches, depending on the application and the length of the stair. Generally, the longer the run of stairs, the thicker the stair will be poured.
