A History of Testing, Innovation Drives Today's Performance

Simpson Strong-Tie's commitment to product design and testing over the years has resulted in us taking a whole-systems approach to building design. One of the key milestones that launched us down this path was the development of our first factory-built wood shearwall — the Strong-Wall®.

Our pre-fabricated shearwalls not only represent an alternative to site-built walls, but also helped to improve the quality, consistency and performance of shearwalls in the field. Today, Simpson Strong-Tie offers a full array of patented, code-listed Wood and Steel Strong-Wall shearwalls.

Simpson Strong-Tie Wood Strong-Wall Shearwalls and Wood Strong-Wall SB Shearwalls now code-listed to the 2015 IRC/IBC.

Both the Simpson Strong-Tie Wood Strong-Wall shearwalls and Wood Strong-Wall SB shearwalls conform to ICC-ES Acceptance Criteria AC130. See ICC-ES ESR-1267 for the Wood Strong-Wall and ICC-ES ESR-2652 for the Wood Strong-Wall SB.

The Steel Strong-Wall shearwalls conform to ICC-ES Acceptance Criteria AC322 and are code-listed under the 2012 IRC/IBC (see ICC-ES ESR-1679).
