Simpson Strong-Tie has introduced the Strong-Wall SB shearwall, a prefabricated wood product, offering enhanced design flexibility and greater lateral-force resistance for a broad range of applications,including narrow and tall wall spaces. In areas susceptible to seismic activity or high winds, the Strong-Wall SB provides structural support comparable to that of narrow steel shearwalls. Field-trimmable for custom applications and rake walls,the product fastens to headers with drill zones and a chase for wiring.
