![]() Wall Thickness: ☑0% of nominal wall thickness, as measured at the center of the flat. If it is assumed that both the round and hexagonal tubes are extruded (which is likely for a bike frame) we can ignore any cold-forming or welding issues. Hexagonal tube is likely to be much more expensive as it is a non-standard shape. The radius of any outside corner shall not exceed 3.0 times the specified wall thickness. I cant think of much advantage to using a hexagonal tube, except perhaps cosmetic - but this is subjective. Structural supports, building columns, highway signs, oil field services and communication towers.Ġ.025" times the number of ft of total length.įor square and rectangular structural tubing, adjacent sides shall be square (90°), with a permissible variation of 62° max. Lengths: 3m,5.8m,6m,9m,12m, Customer Specific Lengths Section Size: 20mm x 30mm to 600mm x 500mmĥ. Type : ASTM A500 Square tube, ASTM A500 Rectangle Tubeģ. Grade: ASTM A500 Grade A ,Grade B ,Grade C,Grade DĢ. The steel is produced by one or more of the following processes: Open hearth, basic oxygen or electric furnace.ġ. Great ductility, weldability, and high-temperature properties make 310. This specification covers cold-formed welded and seamless carbon steel round, square, rectangular or special shape structural tubing for construction of bridges, buildings and for structural purposes. Thank you very much for downloading rectangular steel tubing span tables. ASTM A500 is the most common specification for Hollow Structural Sections.
