In building construction, lintels and beams are structural members used to support loads and transfer them safely to walls or columns.
Although both carry loads, their position and function are different.
Why This Topic Is Important
Understanding lintels and beams helps you:
-
✅ Avoid structural cracks
-
✅ Ensure safety above openings
-
✅ Answer common interview questions
-
✅ Improve site execution quality
What Is a Lintel?
Definition
A lintel is a horizontal structural member placed above doors, windows, and openings to support the load from the wall or slab above.
Materials Used for Lintels
-
Reinforced Cement Concrete (RCC) – most common
-
Stone
-
Brick
-
Steel
-
Timber (rare today)
Uses of Lintel
-
🧱 Supports masonry above openings
-
🚪 Transfers load to side walls
-
🛑 Prevents cracks over doors/windows
-
🏠 Maintains structural stability
Example (Site Use)
A RCC lintel is provided above:
-
Doors
-
Windows
-
Ventilators
What Is a Beam?
Definition
A beam is a horizontal structural member that carries loads from slabs, walls, or roofs and transfers them to columns or walls.
Types of Beams (Common)
-
RCC beam
-
Steel beam
-
Cantilever beam
-
Simply supported beam
-
Continuous beam
Uses of Beam
-
🏗️ Supports slabs and floors
-
🧱 Carries wall loads
-
🔁 Transfers load to columns
-
🏢 Forms building framework
Example (Site Use)
-
Floor beams
-
Roof beams
-
Plinth beams
-
Tie beams
Difference Between Lintel and Beam (Easy Table)
| Point | Lintel | Beam |
|---|---|---|
| Location | Above openings | Throughout structure |
| Load carried | Wall load only | Slab + wall load |
| Span | Short | Short to long |
| Structural role | Minor | Major load-carrying member |
| Provided at | Doors, windows | Floors, roofs |
Site Engineer Tip 💡
-
Lintel depth is usually 150–230 mm
-
Lintels are often cast monolithically with beams in RCC buildings
Interview Questions (Quick Prep)
Q: What is a lintel?
👉 A horizontal member above openings to carry wall load.
Q: Is lintel a beam?
👉 Lintel is a type of beam, but with a specific function and location.
Conclusion
-
Lintel supports masonry above openings
-
Beam supports slabs and walls across the structure
Both are essential for safe and durable construction.
