Quick and easy to install, these factory-built shearwalls are a cost effective alternative to site-built shearwalls. The Strong-Wall is a prefabricated shearwall that is designed and engineered for greater flexibility in building design while providing greater lateral-force resistance and load support. Strong-Wall shearwalls are narrower and available in a full array of code-listed products.

The Strong-Wall Wood Shearwall is a prefabricated, specially designed engineered-wood panel that delivers greater lateral force resistance than most site built wood shearwalls. Features include front, back and side access holdowns and top-of-wall connection for easy installation and inspection in various framing applications. Contractors have the ability to field-trim the shearwall for custom heights and rake walls.

Steel Strong-Wall Shearwalls

The Steel Strong-Wall Shearwall is designed as a composite shearwall that features some of the highest allowable loads in the industry while offering the easiest and fastest installation.

Moment frames allow for the construction of larger openings and smaller wall sections while supporting heavier loads and spanning greater distances. Some applications include garage fronts, very large rooms and soft story retrofitting.

The Simpson Strong-Tie Strong Frame is the most efficient and cost effective moment frame that’s factory built and precision engineered for designers, contractors and building owners. Strong Frame moment frames are designed for fast and easy installation, and their simple, streamlined dimension verification and ordering process will keep your project moving forward.

Soft-Story Retrofitting

Many homes in the Bay Area, especially those with attached garages, have a condition known as soft story. This is a situation in which a living space of the house, a bedroom for example, has been built over a large opening such as a garage door. Such an opening has little or no stiffness or shear strength, hence the term “soft-story” meaning a story of a home built over a wall area that is soft in its resistance to lateral movement. Simpson Strong-Tie is a leader of state-of-the-art structural solutions specifically designed to meet the code requirements of soft-story retrofits.
