84"D Galvanized Steel Code Compliant Spiral Stair Kit - 85"H - 144"H

The 84"D Galvanized exterior spiral stair line is created by manufacturing the spiral staircase out of carbon steel. Then, to prepare the stair for exterior use, it goes through a "hot-dipped galvanizing process", which involves numerous steps to prepare the parts to be dipped into a vat of hot zinc. The zinc coats every inch of the staircase to form a protective barrier against the elements. This code compliant kit is designed to comply with Universal Building Code (UBC), International Fire Code (IFC), Building Officials Code Administrators International (BOCA) and International Residential Code (IRC).

Select the floor to floor height range for your stair:

Measure the height from your finished ground floor to the finished floor above that the stair will access. Select the height range below that this floor to floor measurement falls within.

**Note: If (and only if) your floor to floor measurement falls within two possible height ranges:
By choosing the height range with the smaller maximum height your stair will have fewer steps and a larger rise between the steps. Alternatively, by selecting the height range with the larger maximum height, your stair will include more steps and have a shorter rise between the steps.

(For example, if your floor to floor height measurement is 94", it falls within both the 85" to 95" and 93" to 104" height ranges. By selecting the 85" to 95" height range, the stair will include 9 steps, and the height distance between the steps will be 9.4". Or, by selecting the 93" to 104" height range, your stair will include 10 steps and the height between steps will be a shorter 8.54".) 

Choose the rotation for your stair:

Right Hand Up / Counterclockwise Up: As you walk up the stair from the ground floor, the handrail will be on your right side, and you will walk in a counterclockwise direction up the stair.

Left Hand Up / Clockwise Up: As you walk up the stair from the ground floor, the handrail will be on your left side, and you will walk in a clockwise direction up the stair.

Upgrade your treads to include code risers?

 

Add code risers to your stair treads to close the open gap between your risers to less than a 4" space.



This is a code requirement for some states including: Alaska, California, Colorado, Connecticut, Delaware, Florida, Hawaii, Kentucky, Maine, Maryland, Massachusetts, Michigan, Montana, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Oregon, Pennsylvania, Utah, Vermont, Virginia, Washington, Washington DC, Wisconsin. 

Always check with you local code enforcement officer for local code requirements.

Add an additional platform rail?

One railing section is included standard with the spiral stair kit that extends from the pole along one side of the platform. Add an additional platform rail section to your stair platform to create a parallel or L-shaped ( 90 degree) handrail configuration on the platform. This is used when one side of the platform will not be against a wall, such as when the platform is installed in the middle of a deck or balcony. 

* Required Fields

Please enter in the exact floor to floor height for your stair. This will be measured from the finished floor at the bottom level to the finished floor at the top level that the stair will access.

Summary

    The Galvanized exterior spiral stair line is created by manufacturing the galvanized spiral staircase out of carbon steel. Then, to prepare the galvanized steel stairs for exterior use, it goes through a "hot-dipped galvanizing process", which involves numerous steps to prepare the parts to be dipped into a vat of hot zinc. The zinc coats every inch of the staircase to form a protective barrier against the elements. This process creates a maintenance free barrier to prevent the spiral stair from rusting making it a great outdoor choice.

    This code compliant galvanized steel stair kit is designed to comply with Universal Building Code (UBC), International Fire Code (IFC), Building Officials Code Administrators International (BOCA) and International Residential Code (IRC). Always check with you local code enforcement officer for local code requirements.

    Finish:

    The hot-dipped galvanizing process ends up with an industrial gray finish, that some customers are looking for, which actually bonds the steel to the zinc alloy. You can paint the galvanizing at your home if you properly prepare the surface and use the correct paint. The hot-dip galvanizing process uses a multi step process to prepare the steel and these particular galvanized steel spiral stairs are done with a very high quality of care. A hot alkali solution is used, then a dilute acid solution, and finally dipped in flux or a heated bath of Zinc Ammonium chloride solution which ensures that all the rust, paint, oil, etc is completely removed. All those cleaning steps ensure that a proper bond can occur between the steel and zinc alloy dipping process which chemically bond the zinc protection to the steel. Finally, each individual piece is hand checked for quality and to ensure no sharp edges are left from the galvanizing dip

    Standard Features:

    • Hidden weld and hardware design visually maintains sharp, crisp lines for an overall finished look.
    • Open tread ends
    • 1" Round aluminum balusters
    • Baluster pockets - which allows the baluster to mount inside the tread corner
    • Diamond pattern tread covering provides a non-slip surface while providing architectural styling.
