A History of Testing, Innovation and Performance

Simpson's commitment to product design and testing has grown and expanded over the years to include 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®.

The introduction of pre-fabricated shearwalls not only brought an alternative to site-built walls, but also helped streamline the quality, consistency and performance of shearwalls in the field. Today, Simpson offers a full array of code-listed Wood and Steel Strong-Wall Shearwalls.
