Uses of Steel Gusset Plates

Steel Gusset plates are used for various structures. Steel Gusset plates are used to connect beams and columns or to connect truss members. They can be either the only way of connecting the beam and columns or they can be used with bolts and welds.

Steel Gusset plates are therefore used in most metal weight-bearing structures, but the material and size of the gusset plate varies based on the structure. Bridges usually require thick sheets of steel for their gusset plates, but trusses sometimes only require small sheets of aluminum for their gusset plate.

The size and strength of the gusset plate depends on size and the function of the structure. The larger the force on the connecting members, the larger the size of the gusset plate. Gusset plates provide an easy way to retrofit structures that can no longer safely support the applied loads.
