UPN channel with tapered flanges sizes with their own page
UPN flange slope
The inner faces of the flanges are sloped: 8 % up to UPN 300 and 5 % above. The flange thickness tf is the value at the point where the standard measures it, so the flange is thicker next to the web and thinner at the tip. The model follows that rule.
UPN channel dimensions and properties
The section dimensions come from steel mill and stockholder catalogues. Area, mass per metre, second moments of area, section moduli and radii of gyration are calculated on the same section as the CAD file, root radii included, and checked against the catalogues to within 1 %. The STEP file is a 1,000 mm length; the DXF and DWG hold the section at 1:1.
UPN 320 is not included yet: its calculated radius of gyration differs from the catalogues by just over 1 %.
The value e is the distance from the back of the web to the centroid, which you need to place the channel in a frame or to check eccentric loads. At UPN 100 it is 1.551 cm.
UPN channels: common questions
- What are the dimensions of a UPN 100?
- 100 mm high and 50 mm wide, with a 6 mm web and 8.5 mm flanges. It weighs 10.56 kg per metre.
- Is UNP the same as UPN?
- Yes. UPN is the German-derived name and UNP the one used in some other countries for the same European tapered flange channel.
