    en.wikipedia.org/wiki/I-beam

    ISMB: Indian Standard Medium Weight Beam, ISJB: Indian Standard Junior Beams, ISLB: Indian Standard Light Weight Beams, and ISWB: Indian Standard Wide Flange Beams. Beams are designated as per respective abbreviated reference followed by the depth of section, such as for example ISMB 450 , where 450 is the depth of section in millimetres (mm).

  3. DIN 1025 - Wikipedia

    en.wikipedia.org/wiki/DIN_1025

    DIN 1025 is a DIN standard which defines the dimensions, masses and sectional properties of hot rolled I-beams. The standard is divided in 5 parts: DIN 1025-1: Hot rolled I-sections - Part 1: Narrow flange I-sections, I-serie - Dimensions, masses, sectional properties; DIN 1025-2: Hot rolled I-beams - Part 2: Wide flange I-beams, IPB-serie ...

    en.wikipedia.org/wiki/Rail_profile

    Sizes under 100 lb/yd (49.6 kg/m) rail are usually for lighter duty freight, low use trackage, or light rail. Track using 100 to 120 lb/yd (49.6 to 59.5 kg/m) rail is for lower speed freight branch lines or rapid transit ; for example, most of the New York City Subway system track is constructed with 100 lb/yd (49.6 kg/m) rail.

  6. ASTM A992 - Wikipedia

    en.wikipedia.org/wiki/ASTM_A992

    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. There are a couple of noteworthy enhancements ...

    So S355 has a minimum yield strength of 355 MPa for the smallest thickness range covered by the relevant standard – i.e. EN10025. [ 2 ] Below is a table indicating the most common application codes.

  9. Weld access hole - Wikipedia

    en.wikipedia.org/wiki/Weld_access_hole

    The weld access hole or rat hole is a structural engineering technique in which a part of the web of an I-beam or T-beam is cut out at the end or ends of the beam. The hole in the web allows a welder to weld the flange to another part of the structure with a continuous weld the full width on both top and bottom sides of the flange.
