Strong-Wall Shearwalls

A History of Testing, Innovation Drives Today's Performance

The Simpson Strong-Tie 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 prefabricated shearwalls improve the quality, consistency and performance of shearwalls in the field.

Simpson Strong-Tie has two products in our prefabricated shearwall family, the Steel Strong-Wall® (SSW) and the Strong-Wall wood shearwall (WSW). The Steel Strong-Wall shearwalls conform to ICC-ES Acceptance Criteria AC322 and are code-listed under the 2015 IRC/IBC (see ICC-ES ESR-1679).The Strong-Wall Wood Shearwall is code-listed to the 2015 IRC/IBC and conform to ICC-ES Acceptance Criteria AC130.

The latest addition to the Strong-Wall family is our new Strong-Wall site-built portal frame system (PFS). The PFS is a kit of parts that provides Designers, engineers, and builders in prescriptive markets with an easy way to meet code-required wall-bracing requirements for garage portal frames or other wide openings. The PFS is a cost-effective option to site-built walls by providing a turnkey solution while maintaining aspect ratios and design features. The PFS can significantly cut contractor time on-site and reduce call back issues associated with complex site-built alternatives.

Steel Strong-Wall Shearwalls

Working with specifiers, builders and contractors has given Simpson Strong-Tie insight into the needs of the various players in the design and construction process. This insight has enabled Simpson Strong-Tie to design a composite shearwall that features some of the highest allowable loads in the industry while offering the easiest and fastest installation: The Steel Strong-Wall shearwall.

Strong-Wall Wood Shearwalls

The new Strong-Wall Wood Shearwalls offer the latest product enhancements with front, back and side access holdowns and top-of-wall connection that allow for easy installation and inspection in various framing conditions. The Strong-Wall Wood Shearwall delivers greater lateral-force- resistance performance than most comparable wood shearwalls while providing installers the ability to field-trim the shearwall for customized heights and rake walls.

Site-Built Portal Frame System for Prescriptive Design 

The Strong-Wall site-built portal frame system (PFS) provides Designers, builders and contractors in prescriptive markets with an easy way to meet code-required wall-bracing requirements with narrow wall widths. Simple and quick to install, the PFS is a cost-effective alternative to IRC braced-wall solutions.

Legacy Wood Strong-Wall Shearwalls


The original legacy Wood Strong-Wall shearwalls are being phased out. Simpson Strong-Tie will guarantee availability until December 31, 2018. We currently have two prefabricated shearwalls that can be used as replacements: the Strong-Wall Wood Shearwall and the Steel Strong-Wall.

Visit our Legacy Wood Strong-Wall® Rationalization FAQ for more information.

The legacy Strong-Wall shearwall can be installed around window and door openings, on garage wing walls, interior walls or any other locations where increased lateral resistance is required. Strong-Wall shearwalls can reduce the amount of wall space required for shearwalls, allowing for more windows and doors in house designs.
