What & Why
Lintels are structural beams that carry loads over an opening such as a door, window, or HVAC penetration. Reinforced masonry lintels are usually the most convenient. Masonry lintels may be 1 or more courses tall, with horizontal reinforcement grouted in place. Use special lintel units (u-shaped, with a solid base) where the bottom of the lintel will be exposed in service. Loose steel lintels (angles, T-sections, wide-flange sections, or channels with base plates) may also be used to support masonry over an opening.

Reinforced masonry lintels are inherently fireproof and provide a uniform appearance once in place. Masonry lintels will have to be shored, however, until the grout has gained enough strength to resist applied loads. Steel lintels require no shoring, but can interfere with jamb steel in reinforced masonry construction where the lintel bears on each side of the opening. Steel lintels must be fire-proofed and have MSJC. Loose steel lintels are usually a better choice to support thin veneers; reinforced masonry lintels are often used in load-bearing walls.
