About WIJMA

The Wood I-Joist Manufacturers Association (WIJMA) is a non-profit organization representing major producers engaged in the manufacture of prefabricated wood I-joists and structural composite lumber (SCL).

The purpose of WIJMA is to provide technical assistance and information to the residential and commercial construction industries and to engage in activities that enhance and increase the use of prefabricated wood I-joists and structural composite lumber in the construction industry. WIJMA membership is open to and comprised of technical representatives of prefabricated wood I-joist and SCL producers.

Meetings are generally held twice a year in conjunction with the ASTM-D07 meetings. To address specific issues, WIJMA forms tasks groups made up of representatives of producer and associate members.
