EN 10088-3 Stainless Steel Sections in 1.4301 1.4404 and 1.4462

Shaanxi Shangyou Stainless Steel Co., Ltd. supplies en 10088-3 stainless steel structural sections for international B2B projects that require corrosion-resistant structural geometry, dimensional traceability and clear inspection documentation. Buyers should define the product by complete section dimensions rather than by a nominal name alone. For this page, the key RFQ geometry is agreed section series/drawing and dimensional requirements. Length, quantity, surface condition, tolerance and the intended service environment should be stated before quotation so the actual production route can be selected.

The governing standard depends on how the section is produced. EN 10088-3:2023 / BS EN 10088-3:2023 for general-purpose stainless sections. EN 10088-5 may be relevant to construction-purpose sections when specified; structural design is separate. This distinction is important because a material delivery standard does not replace a structural design code, and a hot-rolled specification should not be automatically assigned to a cold-formed or welded built-up shape. The quotation and MTC should identify the agreed product route and standard revision.

Manufacturing may use hot/cold formed or other section route permitted by the agreed product specification and project. The route affects corner radius, weld appearance, straightness, dimensional flexibility and cost. Hot-rolled or extruded profiles normally show natural mill radii; formed profiles show bend radii; laser-welded built-up sections can provide sharper corners and independent web/flange thicknesses. If the profile is architecturally exposed, specify weld dressing, grain direction, polishing and surface protection before production.

Grade selection should follow the environment and fabrication route. 304 is a practical general-purpose choice, 316L is preferred where chloride exposure or corrosive washdown is more relevant, and duplex 2205 can provide higher strength and stronger chloride-related corrosion resistance. Special grades such as 2507 or 904L should be offered only after confirming material availability, production route, MOQ and inspection requirements.

Typical applications include General industrial structures, Equipment frames, Food/beverage supports, Architectural sections. Shangyou can coordinate cut-to-length, dimensional inspection, PMI, heat-number traceability and export packing, with project-specified NDT or third-party inspection where required. For an efficient RFQ, send grade, standard, agreed section series/drawing and dimensional requirements, length, quantity, surface, manufacturing-route preference, inspection documents and destination. For load-bearing members, the project engineer must separately confirm design capacity and connection requirements.

• General industrial structures
• Equipment frames
• Food/beverage supports
• Architectural sections
• Chemical process supports
• European project procurement

Engineering note: EN 10088-3 is a technical delivery standard for general-purpose stainless sections, not the European structural design code or a universal dimensional standard.

Send grade, governing standard, agreed section series/drawing and dimensional requirements, length, quantity, surface, tolerance, manufacturing route and inspection/document requirements. A drawing is preferred for non-standard sections.

It specifies technical delivery conditions for stainless semi-finished products, bars, rods, wire, sections and bright products for general purposes. It is not a structural design code.

EN 10088-3 covers general-purpose stainless sections; EN 10088-5 addresses stainless bars, rods, wire, sections and bright products for construction purposes when specified by the project.

Cut-to-length and secondary fabrication can be quoted from drawings. State hole diameter, location, edge distance, tolerance, end condition and any deburring or surface-restoration requirement.

Mill, descaled/pickled, ground, brushed or polished finishes may be available depending on the section and starting route. Internal corners and welds can limit uniform decorative finishing.

PMI and MTC / EN 10204 3.1 can be specified for alloy verification and traceability. State whether sampling, 100% PMI or third-party witness is required.

Yes, project inspection can be arranged when the method, extent, acceptance criteria, document format and witness/hold points are defined before production.

Long profiles are normally bundled with suitable supports and protective wrapping. Finished or visible surfaces may require separators, film or additional protection against abrasion.

No. Stock, regular production and made-to-order status vary by grade, section and manufacturing route. Availability should be confirmed against the actual size list.

Price depends on alloy grade, section geometry, production route, length, quantity, surface finish, machining, inspection, packing and current raw-material conditions.
