UPN Channel: Dimensions and Weight Chart
Quick Answer: UPN channels (European Standard U-Channels with tapered flanges) range from UPN 50 to UPN 400. Dimensions and weights are standardized per EN 10279. The number after “UPN” indicates the channel depth in millimeters. Common structural grades are S235, S275, and S355 per EN 10025.

h = height, b = flange width, tw = web thickness, tf = flange thickness. Values per EN 10279.
Key Specifications
Flange geometry: UPN channels have tapered flanges with an approximately 8% inner slope. This distinguishes them from UPE channels, which have parallel flanges and are easier to bolt.
Material grades: UPN channels are typically supplied in S235JR, S275JR/J0/J2, or S355JR/J0/J2 per EN 10025-2. For elevated temperature service, S355K2 or normalized grades may be specified.
Tolerances: EN 10279 specifies dimensional tolerances for height (+/-2 mm for h up to 200, +/-3 mm above 200), flange width (+/-2 to 3 mm), and web thickness (+/-0.5 to 1.0 mm).
Moment of inertia: The strong-axis moment of inertia (Iy) ranges from 26.4 cm4 for UPN 50 to 20,350 cm4 for UPN 400. For structural calculations, always use section properties from the manufacturer’s test certificate or verified EN 10279 tables.
UPN channels are commonly paired with IPE/IPN beams in building frames and with RSA steel angles for bracing and secondary steelwork.
