What is a lintel in masonry?
A lintel is a structural member placed over an opening in a wall. In the case of a brick masonry wall, lintels may consist of reinforced brick masonry, brick masonry arches, precast concrete or structural steel shapes.
What are steel lintels used for?
A lintel is a structural horizontal support used to span an opening in a wall or between two vertical supports. It is frequently used over windows and doors, both of which represent vulnerable points in a building’s structure. Lintels are generally used for load-bearing purposes, but they can also be decorative.
What are the different types of lintels?
Lintels are classified into the following types according to the elements of their development:
- Timber lintel.
- Stone lintel.
- Reinforced concrete lintel.
- Brick lintel.
- Reinforced brick lintel.
- Steel lintel.
How are steel lintels held into position?
Place the steel lintel into position at the top of your opening, so that it slides into the slot you have created, and lies flat against the front of the wall. Use your hammer or small sledge to drive the lintel into position.
How thick are steel lintels?
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.
How do you replace a lintel on a brick wall?
How to replace or remove a lintel

- Step 3 – Remove bricks.
- Step 4 – Remove and replace lintel.
- Step 5 – Replace bricks.
- Step 6 – Leave 24 hours.
Which way round do concrete lintels go?
The bar is in the centre to enable the lintel to work upright or on its side. Upright would be stronger but horizontal would be strong enough for this application. Other lintels have bars in the bottom, they can only be used in the orientation with the bars at the bottom.
Do concrete lintels have steel in them?
Concrete lintels usually have steel rods running the length of the beam to increase their strength under tension. You can buy pre-stressed concrete lintels, which are significantly lighter than standard concrete.

How can you tell if a lintel is concrete or steel?
The easiest way to tell if a lintel is concrete or steel is by appearance. Concrete lintels are often gray in color and look similar to a concrete block.

Are concrete lintels stronger than steel?

Why choose one-piece steel lintels for masonry cavity walls?
One-piece steel lintels for masonry cavity walls offer an excellent balance of strength, weight, durability, performance and cost effectiveness. They are easier to detail and faster to install than alternatives like separate lintels and are capable of providing support over openings in domestic and non-domestic buildings alike.
What are loose angle lintels?
Loose angle lintels are used in brick veneer and cavity wall constructions where the lintel is laid in the wall and spans the opening. This type of lin tel has no lateral support. Figure 1a shows this condition.
