Any joint angle to 120°, any leg from 30 to 200 mm. The UL tier replaces the solid web with a truss whose members are sized against the material's own proof stress — so the aluminium version is not simply the steel one in a lighter metal.
All tangent arcs and lines. No splines, no facets. This profile is 13 arcs and 17 straight lines — and nothing else. Every curve is a true arc your CAM follows as an arc — not a chord, not a polyline pretending to be a radius, not a mesh someone exported and hoped you would not measure.
A real solid, not a mesh. Watertight, positive volume, and the mass agrees with the flat profile it was cut from — every SKU is checked for that before it ships.
Drop it straight into your assembly. S275 · EN 10025-2 S275JR, 608 g as modelled, with the holes deducted.
Plate thickness follows the recommended band L/20–L/5, snapped to the stock size nearest the band's geometric mean. No lookup table, no gaps between sizes.

Plan view, projected front view, and a load-rated data block — drawn by the engine from the same DXF you get, so the view and the cut file cannot disagree about what the part is.
Every dimension on it is checked for legibility before the sheet is issued: nothing off-sheet, nothing sitting on the part, nothing on top of another dimension.


Our own spec, not a copied national one. A linear-elastic solve plus a linear eigenvalue buckling step on the same model, applied at the rated load with the real restraint — then read against yield, against margin, and against stability.
Peak 220 MPa at the bore, 0.189 mm of deflection that fully recovers, and mode 1 buckling at λ₁ 194 × the rated load. The rating is set by the governing criterion, and the report says which one and why.
