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 or local
codes may override aspects of these codes. Before ordering a spiral stair, check
with your local building inspector for the dimensional requirements. Salter
Industries manufactures a 62" diameter stair and
72" diameters stair to
comply with these codes.

| • |
30 degree stair treads |
| • |
3 or 4 balusters per tread 2015P
(maximum space of
4"). |

SPECIAL
HALF TURN STAIR PACKAGE
|
|
The half turn is a
unique stair that can solve many situations when a traditional spiral will not
fit. Most spiral stairs require a square opening which many jobs cannot provide.
It is common to have a 36" wide space with extra length. It is not a code
package but does provide an excellent secondary stair.
