Since 1952, American Institute of Timber Construction (AITC) has pioneered laminated timber research in conjunction with the Forest Products Libratory, other associations and grading agencies to develop standards relied on by Engineers, Architects, Code Agencies, and Contractors. AITC Inspectors make periodic audits of all licensed AITC active member plants. A member since 1957, Timberweld is the longest standing member of AITC. We are proud of our long association with AITC and their contribution to the laminated timber industry.
