2. 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 ...

3. ASTM A500 - Wikipedia

   en.wikipedia.org/wiki/ASTM_A500

   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 ...

4. Structural steel - Wikipedia

   en.wikipedia.org/wiki/Structural_steel

   Structural steel. Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices ...

5. ASTM A53 steel - Wikipedia

   en.wikipedia.org/wiki/ASTM_A53_steel

   ASTM A53 pipe is sized according to the nominal pipe size (NPS) system. It is commonly available with national pipe thread ends or with plain cut ends. It can be used for steam, water, and air conveyance. It is also weldable and can be used in structural applications, although ASTM A500 tube, which is available in the same NPS sizes, is ...

6. Cold-formed steel - Wikipedia

   en.wikipedia.org/wiki/Cold-formed_steel

   Cold-formed steel. Cold-formed steel (CFS) is the common term for steel products shaped by cold-working processes carried out near room temperature, such as rolling, pressing, stamping, bending, etc. Stock bars and sheets of cold-rolled steel (CRS) are commonly used in all areas of manufacturing. The terms are opposed to hot-formed steel and ...

7. Tube (structure) - Wikipedia

   en.wikipedia.org/wiki/Tube_(structure)

   Tube (structure) John Hancock Center in Chicago, designed in 1965 and finished in 1969, is an example of the trussed tube structural design. In structural engineering, the tube is a system where, to resist lateral loads (wind, seismic, impact), a building is designed to act like a hollow cylinder, cantilevered perpendicular to the ground.
