Metal Building Systems Manual, 2024 Edition

The Metal Building Manufacturers Association (MBMA) is a trade association whose mission is to enhance the collective interests of the metal building systems industry. MBMA provides technical leadership to the industry through an active technical agenda, educational programs and through outreach to building design professionals. The numerous research programs undertaken by MBMA have led to significant contributions to raise the state of the art in efficient and cost-effective structures for over 60 years. The Metal Building Systems Manual continues to be the nationally accepted and referenced manual for common industry practices, design procedures and performance guide specification language.

The Metal Building Systems Manual provides a practical and comprehensive resource that will help engineers, architects, building officials and plan checkers ensure the metal building designs are compliant with the requirements of the International Building Code® (IBC®).

The design recommendations in this manual are based on the 2024 IBC®, American Society of Civil Engineers/Structural Engineering Institute (ASCE/SEI) 7-22 and common industry practices.
