SHS square hollow sections (EN 10219): 20x20 to 100x100 box section dimensions, corner radius + STEP/STL

What are the dimensions of SHS 50x50x3 square hollow section (wall, corner radius, kg/m)? · Standard part · basis: Roymech cold-formed hollow section tables (BS EN 10219:1997 values: size, wall, outside and inside radius, mass, area); radius band from EN 10219-2 as quoted by two mills

Notes

  • SHS (square hollow section, also called square tube or box section) to EN 10219: designation B x B x t, B the outside side and t the wall, in mm. The US equivalent is square HSS (aisc-hss-rectangular-square, inch sizes).
  • Corner radius: EN 10219-2 gives a band for the outside radius, 1.6t to 2.4t for walls up to 6 mm, 2.0t to 3.0t for 6 to 10 mm, 2.4t to 3.6t above 10 mm (Nippon Steel Kenzai and the Ozdemir Boru declaration both print it). The radii in the table and the files are the Roymech section-table values, the middle of each band: 2t up to 6 mm wall, 2.5t at 6.3 and 8 mm, 3t at 12 mm and over, with inside radius = outside radius minus the wall. A real tube from one mill can sit anywhere in the band.
  • Sizes: every row of the Roymech table from 20 x 20 to 100 x 100 mm (53 sizes). The table goes to 400 x 400 mm; larger sizes are not listed here.
  • Files: 25 sizes drawn as 100 mm long extrusions along X, centred on y = 0, z = 0 on the bottom face. Each drawn section area matches the printed area within 1.5 %; the table check also confirms mass = 0.785 kg/m per cm2 within 1.5 % and ro - ri = t on every row.
  • Nominal dimensions only: EN 10219-2 tolerances on size, wall (-10 %), squareness and corner radius are not applied.
  • McMaster-Carr's metric square tube (12, 25, 40, 55, 100 mm) is EN 10305-5 precision tube, not EN 10219; it is linked as a CAD source, not as an equivalent.

Questions

What is SHS?

Square hollow section: cold-formed steel tube with a square cross-section, sized B x B x t in mm to EN 10219 (structural) - the US equivalent is square HSS.

What is the corner radius of SHS 50x50x3?

Outside 6 mm (2t), inside 3 mm in the Roymech EN 10219 table; the standard allows 1.6t to 2.4t outside for walls up to 6 mm.

How heavy is SHS 50x50x3?

4.25 kg/m, section area 5.41 cm2.
