Most commercial concrete lintels need a minimum thickness of 6 to 8 inches, especially above larger openings. The National Concrete Masonry Association (NCMA) is a not-for-profit organization whose mission is to support and advance the common interests of its members in the manufacture, marketing, research, and appli-cation of concrete masonry products. Through the "arching" behavior some loads may be considered to distribute to either side of the opening and not need to be resisted by. Precast concrete lintels provide essential structural support above windows and doors, distributing weight evenly across surrounding walls whilst offering exceptional durability with lifespans exceeding 50 years.
