Today, AISC's membership represents more than 35,000 fabricators, service centers, producers, engineers, architects, developers, and product suppliers in the structural steel industry, as well as educators and the students who will literally build our future. 

Everything AISC does is intended to increase the use of domestic fabricated structural steel, and we couldn't do it without our members.

Members support many of the crucial services AISC provides to the industry as a whole, such as technical and conceptual assistance from our engineering staff at the Steel Solutions Center. Members empower us to make a difference in tomorrow's building codes, project specifications, and federal regulations and keep America's fabricated structural steel industry on the cutting edge.
