UPE is the short form for channel sections with parallel flanges according to EN 10365 with tolerances according to EN 10279: 2000.
The UPE series with parallel flanges is now also available in stainless steel and is a very interesting alternative to the UPN series.
The UPE profiles have thinner material thicknesses but on the other hand slightly wider flanges than the UPN profiles. However their static values are pretty much comparable.
Due to the characteristic of the UPE channels, architects and engineers are able to reduce weight by 9% when calculating around the strong axis and even 24% when referring to the weaker axis.
Therefore using UPE profiles results in weight saving up to 30% by keeping the same static conditions.
Furthermore the new UPE series match perfectly with the dimensions of the IPE series.
According to EN 10088-3: 1D the following austenitic grades are predominantly used for stainless steel structurals: 1.4301 (304), 1.4307 (304L) , 1.4401 (316) , 1.4404 (316L) and 1.4571.
