I-beams are still available in US sizes from many Canadian manufacturers. In Mexico, steel I-beams are called IR and commonly specified using the depth and weight of the beam in metric terms. For example, a "IR250x33" beam is approximately 250 mm (9.8 in) in depth (height of the I-beam from the outer face of one flange to the outer face of the ...
Height of rail equaled width of foot for each ASCE tee-rail weight; and the profiles specified fixed proportion of weight in head, web and foot of 42%, 21% and 37%, respectively. ASCE 90 lb/yd (44.6 kg/m) profile was adequate; but heavier weights were less satisfactory.
Sizes vary according to the I-joist's intended load and span. Depths can range from 9 + 1 ⁄ 4 to 24 inches (230–610 mm) and reach up to 80 feet (24 m) in length, although 40 to 42 feet (12–13 m) is more common. The intended use for an I-joist is for floor and roof joists, wall studs, and roof rafters in both residential and commercial ...
h = height, t = wall thickness [1] For the two flanges of an Ɪ-beam with the web excluded = + b 1, b 2 = width, t 1, t 2 = thickness, y 1, y 2 = distances from the neutral axis to the centroids of the flanges respectively. [18] For an I Beam including the web
ASTM A992 is currently the most available steel type for structural wide-flange beams. The industry's technical institute describes the standard thus: "ASTM A992 (Fy = 50 ksi, Fu = 65 ksi) is the preferred material specification for wide-flange shapes, having replaced ASTM A36 and A572 grade 50.
