Stairbuilders and Manufacturers Association AWI SMA Standard.
Proposed American National Standard:
AWI SMA 0643 – Wood Stair, Handrail and Guard Systems
The Architectural Woodwork Institute (AWI) and Stairbuilders and Manufacturers Association (SMA) have collaborated to develop the proposed AWI SMA 0643 – Wood Stair, Handrail, and Guard Systems standard. The standard differentiates between structural and aesthetic requirements for stair systems, ensuring that industry professionals can tailor the product to their specific needs. The AWI SMA 0643 – Wood Stair, Handrail, and Guard Systems standard includes a separate installation section, to be used by stair system installers in the field.
The standard draft will be available here for review and balloting through December 16, 2020.
