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.

Circular hollow sections Technical and buying guide
EMRA Steel
Circular hollow sections are specified by outside diameter, wall thickness, material grade and manufacturing route.Read more
Standards and applicability
Keep EN 10219 cold-formed welded and EN 10210 hot-finished routes separate. Numeric S355J2H rows below are EN 10219 references for t ≤ 16 mm, not automatic EN 10210 or S355NH data. The tensile band changes below 3 mm. Elongation is reduced from 20% to 18% where D/t < 15 for CHS or (B+H)/(2t) < 12.5 for RHS/SHS; below 3 mm confirm gauge length and specimen width. The 27 J at −20°C reference requires the applicable impact-testing and subsize rules. Confirm grade, wall, corner geometry, weld inspection and certificate for the actual route.

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.
Circular hollow sections Technical and buying guide
EMRA Steel supports sourcing enquiries for Circular hollow sections. Review product dimensions, grades, standards and inspection requirements before requesting a quotation. Confirm quantity, delivery destination and the required schedule with our sales team.
Circular hollow sections are specified by outside diameter, wall thickness, material grade and manufacturing route.
Specification and dimensions
Specify the following dimensions or analysis details for Circular hollow sections: Outside diameter × wall thickness × length for circular sections; width × height × wall thickness × length for rectangular sections.. The examples below are enquiry references, not a confirmed stock range.
Grades and applicable standards
For structural circular tubes, specify cold-formed welded EN 10219-1 / EN 10219-2 or hot-finished EN 10210-1 / EN 10210-2. State the full grade, for example S355J2H for an EN 10219 enquiry or S355NH for EN 10210, subject to confirmation. Reference weights below identify their geometry basis. Outside diameter is not the same as nominal pipe size DN. Water, gas or pressure service requires its own applicable pipe standard, testing and approval. Confirm coating, end preparation and inspection documents.
Applications and project requirements
For Circular hollow sections, share the intended production process or project specification. Required properties, processing condition, surface acceptance and dimensional tolerances should reflect the actual application. Supply selection should be reviewed against the technical requirements rather than based on dimensions alone.
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.
