PFC Parallel Flange Channels – Stainless Steel
PFC (Parallel Flange Channel) is the British Standard structural channel section defined in BS 4. It closely resembles the European UPE channel but follows a different sizing convention and dimensional series PFC listed in the EN 10365. PFC channels feature flanges that are parallel on both inner and outer faces, making them highly practical for bolted connections and welded fabrications. Montanstahl produces stainless steel PFC channels to the BS 4 dimensional series by laser welding with tolerances according to the EN 10279:2000, addressing demand from the UK market and from projects internationally where British standards are specified.
Key Applications & Use Cases
- Structural framing in UK and Commonwealth construction projects where BS 4 is the specified standard
- Conveyor frames, motor base plates, and mechanical handling equipment in corrosive environments
- Offshore structural members and subsea protection frames built to British standards
- Bridge parapet channels, walkway frames, and drainage channels in coastal and marine infrastructure
- Cold-store and blast-freeze plant framework requiring high corrosion resistance
- Architectural exposed steel in commercial interiors, galleries, and public buildings
- Structural secondary members in modular construction and prefabricated building systems

PFC Channels Profiles FAQ
What is the difference between a PFC and a UPE channel?
PFC channels follow the British Standard BS 4 dimensional series, while UPE channels follow the European EN series. Both have parallel flanges, but the specific dimensions, flange thicknesses, and section properties differ between the two series. Specifiers in UK and Commonwealth projects typically use PFC; continental European projects use UPE or UPN.
Does Montanstahl stock PFC channels in stainless steel?
Montanstahl holds stock of the most frequently ordered PFC sizes in grades 304 and 316L. Less common sizes and specialty alloys are produced to order, typically with competitive lead times thanks to the laser welding process.
Is laser welded PFC channel structurally equivalent to hot rolled?
From a cross-sectional geometry standpoint, laser welded PFC channels match the nominal dimensions of BS 4. The mechanical properties of the parent material conform to EN 10088-3. The laser weld joint has a minimal heat-affected zone and does not compromise the structural performance of the section under normal loading conditions.
Can PFC channels be supplied cut to non-standard lengths?
Yes. Montanstahl offers a cut-to-length service for all structural profiles. Specific lengths, multiple pieces per order, and minimum material offcuts can all be accommodated. Maximum individual length is 15 m.
What test documentation is available for stainless steel PFC channels?
EN 10204 type 3.1 mill test certificates are standard. Certificates of conformance, heat traceability documents, and third-party inspection reports can be arranged for projects requiring enhanced material traceability.
