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.

Steel channels are open structural sections; exact series and dimensions determine the ordered section.

U channels Technical and buying guide

EMRA Steel

Compare UE light channels and UPN channels by section height, flange width, web and flange thickness, and weight per metre.

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.

St37, St44 and St52 · historical DIN 17100 reference

St37-2 / 1.0037	≤0.17	—	—	≤0.050	≤0.050

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.

U channels Technical and buying guide

Compare UE light channels and UPN channels by section height, flange width, web and flange thickness, and weight per metre.

Steel channels are open structural sections; exact series and dimensions determine the ordered section.

Specification and dimensions

Channels: exact section series and designation, overall height, flange width, web thickness, flange thickness and length. State whether the order is UPN, UPE or another specified series. A nominal height alone does not identify the section; angle-leg dimensions do not apply.

Grades and applicable standards

UPN dimensions: EN 10365 / DIN 1026-1; tolerances: EN 10279. The UE light-channel data below refer to the taper-flange series in GOST 8240-97; UE is distinct from UPE. UE reference dimensions and tolerances follow GOST 8240-97; specify EN 10279 separately if required by the order. Confirm the applicable dimensional and tolerance standards in the supply specification. Material enquiries may specify S235JR, S275JR or S355J2 to EN 10025-2, or an agreed grade under the specified material standard. If ISIRI 4477-1 is required, state it explicitly and request matching inspection documents. This list does not declare simultaneous certification or current stock.

Applications and project requirements

Channels are used in frames, supports and fabrication. Orientation, connection details and the specified series matter; a light or heavy label alone is insufficient to establish equivalence.

Inspection and traceability

Agree heat or batch identification, chemical analysis, applicable tests and dimensional checks before ordering. Specify inspection documents, acceptance criteria and any independent inspection requirements.
