[Welded] Stainless Steel I-Beam for custom dimensions beyond standard hot rolled sizes
Stainless steel welded I-beam is fabricated by welding together three separate stainless steel plates — two flanges and one web. The welding process typically uses submerged arc welding (SAW) or laser fusion welding, allowing for custom dimensions beyond standard hot rolled sizes. The flanges can be welded with a square inner corner for easier connections.
| Aspect | Hot Rolled I-Beam | Welded I-Beam |
|---|---|---|
| Forming Method | Hot rolling — one-piece | Welded from three plates |
| Weld Seam | None | Present (flange-to-web connections) |
| Size Range | Standardized; height ≤ 200 mm | Customizable; height > 1200 mm possible |
| Flange Inner Angle | Tapered (8°–12°) | Can be square (90°) |
| Residual Stress | Low | Welding residual stress requires treatment |
| Fatigue Performance | Excellent | Good, but lower than hot rolled |
| Production Cost | Economical for large volumes | Flexible for small batches and custom sizes |
| Best Suited For | Standardized large-scale structures | Custom sizes, large sections, square flange requirements |
| Scenario | Recommended Choice |
|---|---|
| Standard sizes, high fatigue resistance, large quantities | Hot Rolled I-Beam |
| Non-standard dimensions, oversized sections, square flange corners, custom projects | Welded I-Beam |
Welded stainless steel I-beam is produced by cutting stainless steel plates into two flanges and one web, then welding them together to form an I-shaped section.
Zhaotai offers multiple welding processes to meet customer needs, including submerged arc welding, laser welding, plasma welding, and manual welding.
After welding, the beam is straightened, heat-treated to relieve stress, and surface finished through pickling or polishing. Finally, it undergoes quality inspection before shipment.
Mill Finish, Not Polished.
Available surface finishes: polishing, sandblasting, brushed, embossing, painting, etc. Please contact us for inquiries.
Stainless steel can be magnetic depending on its internal structure. Austenitic grades like 304 and 316 are normally non-magnetic, but ferritic (430) and martensitic (410) grades are magnetic due to their different crystal structure. Even 304 or 316 may become slightly magnetic after cold working such as bending or stamping, which transforms some austenite into martensite. Therefore, magnetism does not indicate quality — it simply reflects the steel's microstructure and processing history.
For standard materials and sizes held in stock, delivery is guaranteed within 3 days of payment receipt. For products requiring custom dimensions or surface finishes, the lead time is 7 to 15 working days after payment confirmation. Specific delivery schedules should be confirmed with customer service at the time of order placement.
A substantial inventory is maintained to ensure prompt delivery. Stock availability varies by material grade and dimensions. To avoid potential delays, please confirm current stock levels with your sales representative prior to placing an order.
Applicable product standards must be specified at the time of order. For projects with specific technical requirements, please provide detailed parameters, tolerance ranges, and other relevant specifications. A dedicated quality inspection department oversees all stages of production to ensure full compliance. Upon completion, accurate measurements, inspection images, video documentation, and material test reports are provided for customer confirmation.
Complimentary samples are available in any size; however, international shipping fees apply. These charges are deductible from future order payments following formal cooperation. Customized samples are also available for a fee. For further details, please consult your sales representative.
Custom markings on outer packaging are available upon request at no additional cost. Once the marking design is approved, it will be affixed using waterproof tape. If no specific marking is requested, packaging will be shipped without markings by default.
Material grade, dimensions, and other identifying information may be spray-marked directly onto the steel plate surface upon request. For applicable charges, please consult your sales representative.
Standard wooden pallet packaging is provided at no extra cost, with a loading capacity of 1 to 3 tons per pallet. Alternative packaging options, such as iron pallets, are available upon request. Please contact your sales representative for details — bulk orders qualify for preferential pricing.
We maintain partnerships with multiple freight forwarders to offer competitive land, air, and sea freight options. If you have a preferred freight forwarder, we can arrange delivery to your agent's warehouse or to the designated port of shipment.
Factory inspections and product inspections are fully supported. Customers are welcome to visit our facility for in-person inspections. Alternatively, third-party inspection agencies, including SGS, may be arranged to conduct on‑site inspections.
