What is a girder?

A girder is a primary horizontal beam that is used to support a roof or floor in a building. They are typically made of steel, wood, or reinforced concrete and are designed to distribute the weight of the structure evenly across multiple support points.

Girders are often used in industrial buildings, bridges, and other large structures where a strong, rigid support is needed. They can be straight or curved, depending on the specific design requirements of the structure.

Girders are typically supported by columns, walls, or other vertical supports, and are fastened in place using bolts, welds, or other connection methods. They are essential components of a building's structural system and play a crucial role in maintaining the integrity and stability of the structure.
