Difference between Beam and Girder

When it comes to different types of steel beams, there are two main categories: beam and girder. Many people might not know the difference between the two, but understanding the difference is important when determining which type of beam or girder to use for your project.

What is Beam?

A beam is a support element used in construction. Beams are used to support loads that are perpendicular to the element, and they are typically made of wood, steel, or concrete. Beams are often used in floors, roofs, and bridges. They can also be used in walls, but this is less common. The size and type of beam used will depend on the load it needs to support and the span of the support.

Beams are generally considered to be load-bearing elements, meaning that they support the weight from other parts of the structure. This can include the weight of the materials used to construct the beam itself, as well as any live loads that may be placed on the beam (such as people or furniture). In some cases, beams may also be used for decorative purposes. For example, decorative wooden beams are often used in ceilings or as support for a fireplace.

What is Girder?

Girder is a structural support element used in a wide range of construction projects from commercial to residential. Girder supports can hold large loads as it has a greater structural depth, often being placed up against walls for extra stability. An experienced professional can design Girder to be integrated into the structure in such ways that goes unnoticed, yet its support helps prop up the entire building.

Girder structures aren’t specific to any certain application; their strength makes them ideal for any project needing robust support. Girder provides multi-directional distribution capabilities, ensuring the safety and security of large structures. Its versatility and strength make Girder one of the most important structural elements in many buildings and other constructions today.

Difference between Beam and Girder

Beams and girders are both structural support elements used in construction.

  • Beams are typically horizontal elements that span between supports, while girders are usually larger and heavier, with a more complex structure that allows them to bear greater loads.
  • Girders are often used to support bridges or other structures where long spans are required. Beams can be made of wood, steel, or concrete, while girders are usually made of steel or reinforced concrete.

When designing a structure, engineers must consider the load-bearing capacity of the beams and girders as well as the size and weight of the materials used.


Beam and girder are two different types of structural members used in construction. Beams are typically made from wood, steel or concrete, while girders are always made from metal. Girders are thicker and stronger than beams, so they can span further distances. When deciding which type of member to use for your project, consider the loads that will be applied to the structure and the distance between supports.
