Notes

  • Type codes as Misumi prints them: four slots: HFS, EFS, NFS, NEFS, GFS, CAF, HFSY; 3-side slot (1 side flat): HFSF, EFSF, NFSF, NEFSF, GFSF; two-side slots (two flats): HFST, EFST, NEFST, GFST; two slots on opposite sides: HFSH, EFSH; one-side slot (three flats): HFSC, EFSC; light type: NFSL, HFSL, HFSLF, HFSLT, HFSLB; heavy type: HFSG; angled: HFS30A, HFS45A, HFS60A; curved: HFSR, NFSR.
  • T-slot extrusion comes in more than the four-slot square. Misumi's catalog names the arrangements: 3-side slot (one side flat, code F), two-side slots (two flats, T), two slots on opposite sides (H), one-side slot (three flats, C), plus light (L), heavy (G / HFSG) and angled 30 / 45 / 60 degree types. Makers elsewhere call the same things 1-slot, 2-slot adjacent, 2-slot opposite, 3-slot, closed-slot or smooth-face extrusion; the codes below are Misumi's, the words are the catalog's. The first table of numbers is the catalog's type code table; the second is every variant whose mass, area, Ix and Iy were legible.
  • Ix and Iy are in units of 10^4 mm4 as printed (0.742 means 0.742 x 10^4 mm4). Where the catalog prints one value for the pair (HFSF6-6060 and HFST6-6060 share one row), they are shown as one row. Ix and Iy are in the order the catalog prints them (3060: 5.33 then 20.56); the text read here does not say which axis is which, so check against the drawing before using either in a beam calculation.
  • Base profile values agree with the existing profile pages: 2020 183 mm2 and 0.5 kg/m, 2040 324 and 0.88, 4040 (5 series) 472 and 1.28, 3030 333 and 0.9, 3060 592 and 1.6, 6060 971 and 2.63, 4545 777 and 2.1, 4590 1534 and 4.14.
  • What the numbers say about the shape: against the 183 mm2 four-slot 2020, the 3-side type is 195 (+12), two-side 196 (+13), opposite-side 199 (+16) and one-side 208 (+25) mm2. The shape of the flat faces is a drawing, not text, so none is modelled here; take Misumi's CAD for the variant, and use the base profile's files only where the flat face does not matter.
  • Left out because the table was not readable: the 8 series (40 / 80 mm square, 10 mm slot) F, T, H, C, L and G values (Misumi page not legible), 6 series 6090 / 60120 (one row shared with the economy EFS type), the economy (Misumi Economy Series LCF) 4040 variants (row alignment unclear), 80/20 closed-slot and smooth types (80/20 pages could not be read here), and every 2 x 2 or larger 3-side type except those shown.
  • Files: none. The dimensioned cross-section drawings of these variants are images; a file drawn from the base profile with a guessed flat face would be wrong in the one place that matters. The base profiles with true-size STEP and STL are the related pages. Misumi's own CAD for each variant is on its product page.

Questions

What is a 1-slot (one open slot) 2020 extrusion?

Misumi's HFSC5-2020: one-side slot, three flats; 208 mm2 section, 0.56 kg/m, Ix 0.81 x 10^4 mm4.

What is a 2020 extrusion with a closed (flat) side?

Misumi's HFSF5-2020: 3-side slot, one side flat; 195 mm2, 0.53 kg/m, Ix 0.834 and Iy 0.746 x 10^4 mm4.

What does F, T, H, C, L, G mean in HFS part numbers?

F: 3-side slot (1 side flat). T: two-side slots (two flats). H: two slots on opposite sides. C: one-side slot (three flats). L: light type. G: heavy type (HFSG); GFS is Misumi's high-rigidity series.

What are the section properties of 3030 3-side slot (HFSF6-3030)?

0.92 kg/m, 338 mm2, Ix 3.03 and Iy 2.76 x 10^4 mm4.

What does a heavy 6060 extrusion weigh?

HFSG6-6060: 4.13 kg/m, 1529 mm2, Ix = Iy = 54.2 x 10^4 mm4, against 2.63 kg/m and 971 mm2 for the standard 6060.

Are there 45 degree angled extrusions?

Yes: Misumi HFS45A6-30 (30 mm, 6 series) is 1.08 kg/m, 401 mm2; HFS45A8-40 (8 series) is 1.83 kg/m, 676 mm2.
