Stiffeners are plate elements welded to the webs of beams to resist local buckling under concentrated loads and to manage shear in web panels. They are commonly specified at bearings, load application points, and at regular intervals in deep or slender members. Use the section lookup below to find the key dimensions your structural engineer will need when specifying stiffener plates.
