UPN/UPE channels are manufactured according to European standards (EN 10279) on precision section mills. The hot rolling process controls the inner flange taper (for UPN) or parallel flanges (for UPE) and theoretical weight. The channels are cooled, straightened, and cut to length. They are marked and bundled per standard requirements

High-Precision European Standardized Sections: Manufactured according to European standards (e.g., EN 10025), with strict control over dimensional accuracy and tolerances, ensuring precise matching and interchangeability with standard components in European and international projects.
Excellent Bending and Torsional Stiffness: UPN (tapered flange) and UPE (parallel flange) sections offer good anti-bending capability, suitable for staircase stringers, brackets, and vehicle frame structures, meeting demands for local loading and stability.
Structural Lightweighting and Efficient Construction: Compared to wide-flange H-beams, UPN/UPE sections offer a lighter structural solution for specific load requirements, making them easier to transport, hoist, and quickly assemble on-site.
Extensive Mechanical Manufacturing and Industrial Use: Beyond general construction, their specific geometric shape makes them ideal for manufacturing applications like guides, columns, and supports in machinery, as well as cross-members in vehicles and cranes.
Produced by hot rolling on precision section mills, ensuring parameters like sectional shape and flange end taper fully comply with EN/DIN standards.
Asymmetrical Section: Symmetrical groove structure, uniform force distribution under load.
Better mechanical properties than ordinary channels, cost-efficient.
Fits European standard designs, suitable for international projects.
International Engineering Projects: Construction and structural projects requiring European standards.
Industrial Equipment: Supporting, maintaining, and manufacturing European imported equipment.
Machinery Manufacturing: Precision machinery, conveyor systems, automation equipment frames.
Construction & Infrastructure: Steel structure buildings and bridges conforming to European codes.
