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.
BOCA and UBC Code Package Include:
| • |
30
degree stair treads |
| • |
3
or 4 balusters per tread 2015P
(maximum space of 4"). |
| • |
60
degree platform 1 ¾" thick.
This will provide a minimum of 6'6" headroom. |
| • |
1
¾" x 2" one piece oak handrail. |
| • |
5"
solid oak center column & base plate. |
| • |
Platform rail & balusters. |

| • |

and assembly tools. |

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.
