Building supports are essential components of any structure, providing the necessary strength and stability to hold up the building. Joists, BEAMS, STUDS, ibars, ibeams, and girders are all types of building supports that are used in construction. Joists are horizontal members that support floors and ceilings, while BEAMS are vertical members that support walls. STUDS are vertical members that provide support for walls and ceilings, and ibars and ibeams are steel bars and BEAMS that provide additional support. Finally, girders are large BEAMS that span long distances and provide support for bridges and other structures.
