What Are Girders in Construction?

February 22, 2024

A girder in construction is a metal beam that can bear large loads and act as the primary support for a structure. It can be made from various construction materials including concrete or steel and can be categorized in different ways, depending on what it needs to do. For example, a steel girder is typically designed to support major concentrated loads such as structural pillars or beam reactions and can be referred to as either an I-beam or a box girder.

It is important to understand the difference between a girder and a beam, as they serve very different purposes in a construction project. Girders are typically larger than beams, so they can support more significant and all-encompassing load bearing weight. Additionally, girders are designed to bend, so they can resist and redistribute the weight of a structure.

As such, a girder can be seen as the “skeleton” of a building and is able to provide much more support than traditional beams or joists. This makes them essential for any construction projects that require heavy and specialized load bearing capacity.

For instance, girders are often used in the construction of high-rise buildings because they are able to bear large amounts of weight without compromising the integrity of the structure. Additionally, girders are an essential component of bridge construction, as they allow for the distribution of heavy weight over long spans of land. Finally, girders are also useful in home construction as they can be used to support heavy ceiling and floor joists.
