What is a lintel CMU?
CMU lintel blocks are U-shaped, like bond beam blocks, but they do not have knock-out panels or mesh portions that a builder needs to remove. The bottom part of these blocks is permanent. Horizontal reinforcement bars can be placed in the “U” and the space filled in with grout and cement.
What sizes do CMU blocks come in?

How big is a lintel block?
We produce standard lintels in a full range of sizes, stocking them in 4 x 8, 6 x 8 and 8 x 8 sizes in lengths from 2 feet to 12 feet. We produce U-shaped lintels in 6 x 8, 8 x 8, 10 x 8 and 12 x 8 sizes in lengths from 2 feet to 12 feet.
What is a lintel block?
Lintel blocks are U-shaped horizontal masonry units which are placed above the openings. blocks are arranged in a course such that lintel beam can be formed. Lintel beam the wall portion which is above the opening or between two vertical supports.
How thick should a concrete lintel be?
Steel Lintels Sizes Steel angle lintels should be at least 1/4 in. (6 mm) thick with a horizontal leg of at least 3 1/2 in. (90 mm) for use with nominal 4 in. (100 mm) thick brick, and 3 in.

Are concrete lintels stronger than steel?
It is not a myth that steel lintels are stronger than concrete; this is generally the case, but it is a little more complicated. A high strength prestressed concrete lintel can often offer better supporting properties than a similar steel version at certain lengths and can be considerably cheaper.
What size concrete lintel do I need?
What size concrete lintel do I need? The lintel should be installed with a minimum end bearing of 150mm, so measure your opening and add at least 300mm. Unlike steel lintels, a concrete lintel is often used in visible areas and painted if required.

Measure the size of the open space between the walls where the door/window frame is fitted. Add a minimum of 150mm to each end. For example, for a structural opening or clear span of 1,800mm, the minimum lintel length required will be 1,800 + 150 + 150 = 2,100mm.
How do you calculate a lintel?
How To Calculate Steel Quantity Of Lintel Beam – Bar Bending…
- Length of one bar = 1.2+ (2 x 0.150) – 0.025 =1.475m.
- Length of 5 bars = 1.425 x 5 = 7.125m.
- Weight of steel for 10 mm bar = D²L/162 = 10² x 7.125/162 = 4.398 kg.
- Total length of stirrups = 0.632 x 11nos = 6.952m.
