Are you inquisitive to learn about the difference between girders and beams in construction after much confusion? Are these two different structures or just two names of the same thing?
Girders and beams are two extremely important structures in the construction industry. They are the building blocks of any building and help it maintain its shape and distribute the load.
In this comprehensive article, we will explore the details and critical differences between the two to help you reach a better conclusion. We will delve into different types, materials, and functions of beams and girders, including steel and aluminum beams and i-section and prestressed concrete girders.
Beams
Beams are essential load-bearing structures of any building, used mostly in smaller areas such as roofs and ceilings. They run between two or more major supports and resist any structural deformation that may arise from upward/downward forces, side forces, and bending stresses.
It distributes the weight that might arise from the forces, maintaining the equilibrium of the building and preventing it from collapsing due to its own weight.
Material Used And Types
-
Steel Beams
These are the strongest beams, resistant to corrosion and molds. They have a greater power-to-weight ratio and can withstand higher forces than the other two. However, they are comparatively more expensive and are used in bridges and infrastructure that have the potential to get higher weights.
-
Aluminium Beams
These are lighter than steel beams; hence, they can not withstand the same force as steel beams and might collapse if faced with such weights. For this reason, they are not used in buildings that do not have a lot of force, such as residential ones.
-
Wood Beams
Wood beams are simply known as ‘supporting beams.’ These are used in small spaces and might sag if the space between them is great. They are also prone to getting mold if exposed to environmental moisture. They are often used for decorative purposes. However, they stay the best if the dry environment is engineered according to wood beams.
Girders
Girders are large beams designed to support smaller beams and other structural elements.
They are the backbone of a building. They are comparatively larger structures that support the beams. Girders are necessary for great infrastructure like skyscrapers, bridges, and industries. They carry most of the load that beams distribute to them and also maintain the shape of the building.
Types of Girders
Box Girders
Box girders are mighty girders used in bridges to provide support. They usually form a hollow shape, hence the name. They are enclosed by multiple walls to provide support to giant infrastructure.
They can be fabricated from prestressed concrete, structural steel, or a composite of the two.
Cable Style Girders
These are unique types of girders used in bridges. They support the continuous strands of cable running from towers, where the cable connects girder segments to the pylons, just like in the London Bridge.
They can be fabricated from prestressed concrete, structural steel, or a composite of the two.
I-Section Girders
I-section girders are fabricated by welding plate grinders to give a cross-sectional ‘I’ shape. They’re more potent because the shape helps balance the weight equally and even bear more weight. After all, it resists bending due to the i-shape.
They ensure the stability of the structure for the long term and are used in infrastructures such as bridges, flyovers, and even skyscrapers.
Gondal’s I-section girders are among the strongest due to their remarkable strength and longevity. They are Resilient against heavy loads and extreme environmental conditions and require little maintenance.
These are mounted on two opposite poles and have a web of beams between them.
Key Structural Differences
| Features | Beams | Girders |
| Size | They are typically smaller. | They’re large and robust. |
| Function | They distribute the load and maintain the equilibrium. | Act as a support structure for all the web of beams. |
| Load Capacity | They can bear shorter and lighter loads. | They can withstand heavier loads. |
| Application | They’re more commonly used in building roofs and floors. | They’re generally used in skyscrapers and bridges. |
| Material | They’re made from steel, wood, or aluminum. | These are made from steel and prestressed concrete. |
| Span | They can cover shorter spans. | They can cover longer distance spans. |
Advantages of I-Section Girders
I-section prestressed girders have multiple advantages, making them one of the best options. Gondal’s i-section girders offer lateral stability, versatility, and material efficiency, and there are many benefits to choosing girders in construction.
