At Zhongzheng Stainless Steel Co., Ltd., we take pride in supplying high-quality Galvanized Steel Tubes in round, square, and rectangular profiles. With wall thickness options from 0.8 mm to 3.0 mm and lengths ranging 1 to 6 meters, our products are designed to meet diverse structural and industrial needs. Backed by our factory in Tianjin, China, we serve clients across North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, offering reliable corrosion protection and consistent mechanical performance.
Key Features & Benefits
- Superior Corrosion Resistance – The galvanized coating provides excellent protection against rust and environmental factors, extending service life in outdoor and humid conditions.
- Multiple Cross-Section Profiles – Round, square, and rectangular shapes allow flexible design for handrails, frames, fencing, solar mounting structures, and more.
- Wide Wall Thickness Range – From thin-walled (0.8 mm) for lightweight applications to thicker (3.0 mm) for heavy-duty structural support.
- Customizable Lengths – Standard 1–6 m lengths can be cut or joined per project requirements; special lengths are available upon request.
- Consistent Mechanical Properties – Manufactured under controlled processes to ensure uniform strength, ductility, and weldability.
- Cost-Effective Solution – Galvanized steel offers a favorable balance of durability and affordability compared to stainless steel or aluminum alternatives.
Technical Specifications
| Shape | Wall Thickness Range | Length Range | Typical Applications |
|---|---|---|---|
| Round | 0.8 – 3.0 mm | 1 – 6 m | Handrails, scaffolding, water pipes, structural columns |
| Square | 0.8 – 3.0 mm | 1 – 6 m | Frames, gates, solar racks, furniture |
| Rectangular | 0.8 – 3.0 mm | 1 – 6 m | Trailer parts, railings, structural supports, brackets |
Detailed Product Advantages
- Uniform Coating – The galvanizing process ensures a smooth, adherent zinc layer with no bare spots, providing long-term protection even in coastal or industrial environments.
- Excellent Weldability – Galvanized steel tubes can be welded using standard techniques (MIG, TIG, stick) with proper ventilation; the coating may be locally removed if required.
- Dimensional Accuracy – Our tubes are produced with tight tolerances on outer dimensions and wall thickness, ensuring compatibility with fittings and connectors.
- Versatile End Use – Suitable for both indoor and outdoor projects, including greenhouses, temporary structures, automotive components, and agricultural equipment.
- Ease of Handling – Lightweight compared to solid steel bars, yet strong enough for load-bearing applications; available in bundle packaging for convenient transport.
- Environmentally Friendly – Zinc coating is 100% recyclable, and the steel base can be recycled after the product’s life cycle.
Our galvanized steel tubes comply with international quality standards; specific certifications (such as ASTM A53, EN 10219, or JIS G3444) can be provided upon request. We also offer optional additional treatments like passivation or oiling for extra protection during storage and transit.

Frequently Asked Questions (FAQ)
-
Q: What type of galvanizing is used on your tubes?
A: Standard production uses hot-dip galvanizing (HDG) for a thick, durable coating. Electro-galvanized options are also available upon request for specific applications. -
Q: Can you supply tubes longer than 6 meters?
A: Standard length is 1–6 m, but we can produce custom lengths (e.g., 12 m) subject to order quantity and transportation feasibility. Please inquire with your specific requirements. -
Q: Are the tubes suitable for outdoor use in coastal areas?
A: Yes, the galvanized coating provides excellent resistance to salt spray and moisture. For extremely corrosive environments, we recommend a thicker zinc coating or additional protective painting. -
Q: What is the lead time for a typical order?
A: For standard sizes and lengths, lead time is usually 15–25 days after deposit. Custom orders may take 25–35 days depending on complexity and quantity. -
Q: Do you provide samples for testing?
A: Yes, we can provide small samples (e.g., 30 cm length) for quality evaluation. The sample cost is negotiable, and it can be refunded for bulk orders. -
Q: Can these tubes be painted or powder-coated over the galvanized surface?
A: Yes, with proper surface preparation (e.g., etching), galvanized steel can be painted or powder-coated for aesthetic purposes or additional corrosion protection. -
Q: What is the minimum order quantity (MOQ)?
A: For regular stock sizes, the MOQ is approximately 1 ton or 100 pieces. For non-standard dimensions, the MOQ may be higher. We can discuss based on your project. -
Q: Do you offer any warranty on your products?
A: We warrant the material to be free of manufacturing defects in workmanship and coating. Specific warranty terms can be provided in the sales contract.
