Parallel Flange Channels UPE – Stainless Steel
UPE channels are parallel flange channels defined within the European structural steel standard. Compared to the classical UPN series of the same nominal height, UPE channels offer a higher moment of inertia per unit of mass, making them structurally more efficient when bending resistance is the governing design criterion. The parallel inner flanges also facilitate direct bolted connections without the use of tapered washers. Montanstahl produces stainless steel UPE channels primarily by laser welding, covering the full standard range and custom sizes beyond the catalogue.
Key Applications & Use Cases
- Structural beams and runners in crane systems, jib cranes, and monorail hoists
- Purlins and secondary beams in stainless steel canopy and roofing structures
- Frame and sub-frame components in water treatment and desalination plants
- Supporting channels for access flooring, raised platforms, and mezzanine structures
- Drainage channels and frames in slaughterhouses, dairies, and food production facilitiessystems and machine guards in manufacturing environments
- Architectural feature beams in exposed structural design where corrosion resistance and aesthetics combine
- Racking and shelving systems in pharmaceutical storage and controlled environments
Available Stainless Steel Grades
1.4301 (AISI 304), 1.4404 (AISI 316L) and duplex 1.4462 are the most commonly requested. Other grades including 1.4571 (316Ti) and 1.4539 (904L) available on request.

UPE Channel Profiles FAQ
What dimensional standard governs stainless steel equal leg angles?
Equal leg angles are manufactured in accordance with EN 10056-1 (1998) for dimensions and EN 10056-2 (1993) for tolerances. Montanstahl also produces non-standard sizes outside these norms upon request.steel equal angle bars are dimensionally standardized according to EN 10056-1:1998, with product tolerances defined according to EN 10056-2:1993.
Is UPE channel standardised in stainless steel?
The geometry of UPE channels follows EN 10279 tolerances. Stainless steel versions produced by Montanstahl via laser welding are manufactured to match these dimensional requirements, with material properties conforming to EN 10088-3.
What lengths are available for stainless steel UPE channels?
Standard mill lengths are typically 6 m or 12 m. Cut-to-length service up to 15 m is available, as are specific lengths to minimise offcuts and reduce fabrication waste.
Can stainless steel UPE channels be welded on site?
Yes. Austenitic stainless steel UPE channels can be welded using TIG, MIG or plasma processes with matching filler material. Standard precautions for stainless steel welding apply: control of heat input, back purging for full-penetration welds, and post-weld cleaning and passivation.
Are UPE channels available with a mirror-polished finish?
Polished finishes up to mirror (Ra < 0.05 µm, equivalent to a No. 8 finish) are available for special orders. Such finishes are commonly specified in the architecture, food service, and pharmaceutical sectors where hygiene and appearance are both critical.
