<p>A modular I-beam kit 100 comprises a unitary first flange 102. The unitary first flange 102 has two parallel elongate structures 108 that project perpendicularly from the plane of the flange 102. An elongate channel 106 isformed by the two elongate structures 108. The modular I-beam kit 100 further comprises a web 114 and second flange 112. The plane of the web 114 is perpendicular to the plane of the second flange 112. The web 114 has an elongate free edge for receipt within the elongate channel 106 of the unitary first flange 102. The modular I-beam kit 100 can be used to construct an I-beam of a particular height by altering the size of the web 114 prior to assembly.</p> |
