Gusset plate
Gusset plate
Gusset plate is a plate for connecting beams and girders to columns. A gusset plate can be fastened to a permanent member either by bolts, rivets or welding or a combination of the three. They are used in bridges and buildings, as well as other structures. It is a triangular piece of timber or metal that is used to transfer stresses between connected members and help strengthen the joint between them. The size and strength of the gusset will be determined by the size and function of the structure.
Gusset plates are usually either made from cold-rolled or galvanized steel, based upon their use. Steel gussets can be galvanised if greater protection from rust is required. Galvanized steel offers more protection from rust, so this is usually used when the gusset plate is exposed to the elements. The gusset plate is usually painted to match nearby steel and fixtures and to give it an extra layer of protection.
Timber gussets are often used to strengthen timber roof trusses. Steel gussets are often used to connect beams and girders to columns or connect truss members.
