Applications of Stainless Steel Hollow Bar for Construction
The construction industry increasingly utilizes Stainless Steel Hollow Bar for Construction due to its unique combination of properties. Its inherent corrosion resistance makes it ideal for structures exposed to atmospheric conditions, coastal environments, or industrial pollutants, significantly reducing long-term maintenance costs compared to coated carbon steel. Common grades like 304/304L and 316/316L offer excellent durability and aesthetic appeal.
Structurally, stainless steel hollow bars provide a favorable strength-to-weight ratio. They are employed in various architectural and structural applications, including:
- Load-bearing columns and beams in aesthetically demanding designs.
- Trusses and space frames for roofs and facades.
- Handrails, balustrades, and barrier systems.
- Support systems for canopies and glazing.
- Reinforcement in concrete for enhanced corrosion resistance (e.g., bridge decks).
The hollow cross-section can also facilitate the passage of services or allow for concrete filling for enhanced compressive strength and fire resistance. The material’s longevity ensures structural integrity and visual appeal over decades.
Relevant Properties for Construction Grades:
| Grade | Typical Yield Strength (MPa) | Typical Tensile Strength (MPa) | General Corrosion Resistance |
|---|---|---|---|
| 304L | ~210 | ~520 | Good (General Atmospheric) |
| 316L | ~220 | ~530 | Excellent (Marine/Industrial) |
| Duplex 2205 | ~450 | ~655 | Very High (Chloride Environments) |

Typical Applications
Construction, machinery, automotive, energy, enclosures and fencing, food equipment (for stainless), and general fabrication. Match grade and finish to corrosion, strength, and appearance requirements.
Selection Guide
- Use certified material with Mill Test Certificate (MTC).
- Confirm standards (ASTM/EN/JIS) and tolerances per drawing.
- Match surface finish to application (2B/BA/No.4/galvanized).
- Specify dimensions and acceptable deviation upfront.
- Plan packaging and corrosion protection for transit.
Processing, Packaging and Logistics
We adopt edge protection, waterproof wrapping, rust‑inhibiting paper, fumigated pallets, and strapping suitable for sea freight. Loading photos and weight lists are provided for each shipment.
FAQs
Q: What lead time can I expect?
A: Typically 7–15 days ex‑works for standard sizes; custom processing may extend the schedule.
Q: Can you provide cut‑to‑size service?
A: Yes. We slit, shear, cut, drill, bevel and deburr to drawing to reduce waste and speed installation.
Q: How do you ensure quality?
A: Incoming inspection, process control, and final inspection with traceable heat numbers; third‑party inspection is available.
Q: Do you support small trial orders?
A: We support pilot quantities with consolidated shipping to control cost.
All values are typical and for guidance only; confirm with the datasheet and purchase order before production.
