The truss frame construction system developed by Forest Products Laboratory saves lumber and reduces costs. The use of frame material is reduced by 30 percent. Studies by the North Central Forest Experiment Station and the Forest Products Laboratory show that builder prejudices and architect intluences are major obstacles to greater use of trusses; that raw material procurement and lumber warp are major industry problems; and that variation within some lumber grades, conflicting interpretation of the same regulatory codes, and builders' lack of knowledge about trusses are major truss fabricator concerns. Study results have helped large lumber manufacturers improve their production and marketing practices. The Truss Plate Institute and the Component Manufacturers Council have developed programs to focus members' attention toward improvement in truss marketing and lumber procurement Study results in information to help lumber manufacturers improve production and marketing practices.
