Supporting timbers are an essential part of any building structure. They provide the necessary strength and stability to ensure that the building is safe and secure. BEAMS, which are five letters long, are large pieces of timber used to support the weight of the roof and upper floors. Joists, which are six letters long, are smaller pieces of timber that run perpendicular to the BEAMS and provide additional support. Together, these two components form the framework of a building and are essential for its structural integrity.
