Tiebeams are horizontal wooden structural members that tie the walls of a building together. They are also known as collar beams, crossbeams, or binders. Tie beams have been used in building construction for centuries, as they help stabilize and support the roof structure, preventing the downward pressure from affecting the walls. They are often found in traditional timber-framed houses and barns. Other synonyms for tiebeams include joist beams, raking beams, purlins, and truss beams. In modern construction, steel tiebeams are also commonly used, as they offer greater strength and durability over their wooden counterparts.
