Any business entity engaged in the manufacture of prefabricated wood I-joists or structural composite lumber is eligible to become a member of the association. WIJMA is not staffed. Rather, technical representatives of each producer member periodically meet to discuss and address engineering principles, quality control practices, codes, standards, and industry activities. Each producer member pays annual dues and carries equal voting status.
