Code
Stair Package
|
| If
your area is regulated by the National Building Code (BOCA)
or the Uniform Building Code (UBC) we can provide conforming
spiral stairs. Be aware that your state codes may override
aspects of these codes. Before ordering a spiral stair,
check with your local building inspector for the dimensional
requirements. The smallest stair available to still maintain
the building code is a 5' diameter. Salter Industries
manufacture this stair package in 5', 5'6" and 6' diameter. |

and UBC Code Packages Include: |
| (A) |
30º
stair treads |
| (B) |
