Scope note:

Building technique that uses a skeleton frame of vertical steel columns and horizontal I-beams to support a structure's floors, roof, and walls; valued for steel's strength, durability, and high strength-to-weight ratio. The technique is typically used for larger buildings such as skyscrapers, and for bridges.
