Geometric estimates exclude rolling tolerances, coatings and process losses; hollow and rolled-section references include their own section-table basis. Calculated bar weights use unrounded mass. Values are not measured shipment weights. Confirm length, grade, manufacturing route, packing and supply in the offer; the existing image illustrates the product family.
UPN 80 heavy channel: nominal height 80 mm, flange width 45 mm, web thickness 6 mm and flange thickness 8 mm. Enquiry lengths: 6 m and 12 m, subject to confirmation. Reference mass approximately 8.6 kg/m; calculated bar weights are 51.6 kg for 6 m and 103.2 kg for 12 m. Actual mass depends on rolling tolerances; confirm the mill table and weighing basis. UPN 80

Standards and applicability
Use the exact series and section table: EN 10365 dimensions, EN 10034 I/H tolerances or EN 10279 channel tolerances; a UE/GOST 8240 section is not automatically UPN. Material references below are EN 10025-2, with the actual web/flange thickness band where known. The hub compares 3 < t ≤ 63 mm bands. Tensile/yield values do not establish member capacity. Elongation, orientation, impact specimen and acceptance conditions require the complete order specification.

Selected percentages by mass and test values are reference requirements within the stated scope, not the actual heat analysis or a complete specification. A dash means no value is declared here, not zero. Compare the offered heat and test results with the applicable specification and inspection document. If EN 10204 type 3.1 is required, agree document availability, heat traceability and test scope before ordering.
Inspection and export enquiry
Send the exact product, size, full grade and standard edition, delivery condition, quantity, test requirements and named destination. Confirm cutting, coating, bundle or coil mass, protection, unloading and the Incoterms delivery point in the quotation. The destination guidance below supports port and inland comparisons; it does not confirm local stock or a fixed price.
Chemistry references and commercial grades
St37, St44 and St52 · historical DIN 17100 reference
Ladle-analysis reference for St37-2, St44-2 and St52-3 at t ≤16 mm only. Bare St37/St44/St52 names need a suffix, edition and delivery condition. Other thicknesses and product analysis have different rules. These legacy grades are not automatically equivalent to EN grades or interchangeable with CK45/CK60. For semi-finished feedstock, agree chemistry and downstream qualification separately.

Reference values are not shipment analysis or an inventory promise. Agree the complete specification, sampling basis, test methods and acceptance limits before ordering; confirm actual results on the heat/lot certificate. A dash means no numeric limit is stated in this selected reference, not zero.
Size specifications: U channels UPN 80
UPN 80 heavy channel: nominal height 80 mm, flange width 45 mm, web thickness 6 mm and flange thickness 8 mm. Enquiry lengths: 6 m and 12 m, subject to confirmation. Reference mass approximately 8.6 kg/m; calculated bar weights are 51.6 kg for 6 m and 103.2 kg for 12 m. Actual mass depends on rolling tolerances; confirm the mill table and weighing basis. UPN 80
Choosing this specification
For UPN 80, confirm the section series, flange geometry and orientation at connections. Verify the matching section table and required length; the designation alone is insufficient for calculating structural capacity.
