Space frames are structures made up of many pieces of metal or plastic that are put together to form a frame. They can be used to support things like buildings, bridges, and other large structures. They are used often because they are sturdier and stronger than other structures and they can support a lot of weight. They are lighter than other types of structures, which saves money and makes building projects easier. The pieces of the frame are held together with bolts or other methods, like welding, which make them strong enough to hold the weight they are designed to take.
