2. I-beam - Wikipedia

   en.wikipedia.org/wiki/I-beam

   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 ...

3. ASTM A992 - Wikipedia

   en.wikipedia.org/wiki/ASTM_A992

   ASTM A992 steel is a structural steel alloy often used in the US for steel wide-flange and I beams. Like other carbon steels, the density of ASTM A992 steel is approximately 7850 kg/m 3 (0.2836 lb/in 3 ). ASTM A992 steel has the following minimum mechanical properties, according to ASTM specification A992/A992M.

4. Rail profile - Wikipedia

   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.

5. Structural channel - Wikipedia

   en.wikipedia.org/wiki/Structural_channel

   Structural channel. The structural channel, also known as a C-channel or Parallel Flange Channel (PFC), is a type of (usually structural steel) beam, used primarily in building construction and civil engineering. Its cross section consists of a wide "web", usually but not always oriented vertically, and two "flanges" at the top and bottom of ...

6. Hollow structural section - Wikipedia

   en.wikipedia.org/wiki/Hollow_structural_section

   A hot-rolled HSS-box section cut open with a bandsaw, demonstrating residual stress. A hollow structural section ( HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology. HSS members can be circular, square, or ...

7. ASTM A500 - Wikipedia

   en.wikipedia.org/wiki/ASTM_A500

   ASTM A500 is a standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is commonly specified in the US for hollow structural sections, but the more stringent CSA G40.21 is preferred in Canada. Another related standard is ASTM A501, which is a ...
