Structural beams are long, sturdy pieces of material used in construction to support loads and provide stability to buildings and other structures. They are typically made from materials like steel, concrete, or wood and are designed to bear weight from above, distributing it evenly to the supports below. These beams come in various shapes and sizes, such as I-beams, C-channels, and rectangular beams, each serving different structural needs. Properly designed and placed, structural beams help ensure the safety and integrity of a structure, allowing for the creation of open spaces and multi-story buildings.
