Commonly used as a load bearing section, the T-section beam is used as an interlinking point and a support base between wood or steel beams. A common sight in any residential project, these beams allow multiple sections of I or W-beams to be installed in a sizeable area without compromising structural integrity, allowing multi-level projects to be built. Rivets and bolts are used to link beams together, providing a sturdy base that can support the surrounding base structures. Most T-section beams are situated on top of steel pillars and beams as well, providing a balanced steel internal structure.
