Girders often have an I-beam cross section composed of two load-bearing flanges separated by a stabilizing web , but may also have a box shape, Z shape, or other forms. Girders are commonly used to build bridges. A girt is a vertically aligned girder placed to resist shear loads. Small steel girders are rolled into shape. Larger girders (1 m/3 feet deep or more) are made as plate girders , welded or bolted together from separate pieces of steel plate . The Warren type girder replaces

Patented in 1848 by its designers James Warren and Willoughby Theobald Monzani, its structure consists of longitudinal members joined only by angled cross-members, forming alternately inverted equilateral triangle -shaped spaces along its length, ensuring that no individual strut , beam, or tie
