What is the difference between a steel lintel and an RCC lintel?

by | 10 July, 2023

A lintel is a horizontal structural member that spans an opening, such as a door or window, to support the load above it. It helps distribute the weight of the structure above the opening and prevents sagging or collapse.
The main difference between a steel lintel and an RCC (Reinforced Cement Concrete) lintel lies in the materials used and their properties:


  • Steel Lintel: A steel lintel is typically made of high-strength steel, such as structural steel or steel sections like I-beams or channels.
  • RCC Lintel: An RCC lintel is constructed using reinforced cement concrete, which consists of cement, sand, aggregate, and reinforcement bars (usually steel rebars).
    Strength and Load-bearing Capacity:
  • Steel Lintel: Steel lintels have high strength and load-bearing capacity, making them suitable for supporting heavy loads. Steel has excellent tensile strength, allowing it to resist bending or sagging.
  • RCC Lintel: RCC lintels are relatively strong but not as strong as steel lintels. The reinforcement bars in RCC lintels provide additional tensile strength to the concrete, enhancing its load-bearing capacity.


  • Steel Lintel: Steel lintels are prefabricated and usually come in standard sizes. They are installed during the construction phase, with appropriate supports or brackets.
  • RCC Lintel: RCC lintels are typically cast in place at the construction site. Wooden or steel formwork is used to shape the concrete into the desired lintel structure.

Corrosion Resistance:

  • Steel Lintel: Steel lintels may be susceptible to corrosion over time, especially in areas with high moisture or corrosive environments. Corrosion can weaken the steel lintel if proper protective measures, such as coatings or galvanization, are not applied.
  • RCC Lintel: RCC lintels do not face the same corrosion issues as steel lintels since they do not contain metallic components that can rust.

The choice between a steel lintel and an RCC lintel depends on various factors, including the load requirements, architectural design, local building codes, and cost considerations. Steel lintels are often preferred when higher load-bearing capacity is required, while RCC lintels are commonly used in residential buildings and smaller openings. Consulting with a structural engineer or a qualified professional is recommended to determine the appropriate lintel type for a specific application.
