Wuxi Yansheng Technology Co., Ltd., established in 2017, is a professional manufacturer of high-quality steel products with an annual export value exceeding US$50 million. Our DIN EN10210 Galvanized Square Steel Tube Hollow Section is a premium building material designed for structural integrity and long-lasting performance. With a factory spanning 1,000–3,000 square meters and a dedicated team of 101–200 employees, we deliver precision-engineered hollow sections that meet stringent European standards, ensuring reliability for your construction projects.
Our galvanized square steel tubes are produced using advanced cold-forming or hot-rolling processes, followed by hot-dip galvanizing to provide superior corrosion resistance. The DIN EN10210 standard guarantees consistent mechanical properties and dimensional accuracy, making these hollow sections ideal for load-bearing structures, frameworks, and architectural applications. Available in various sizes and wall thicknesses, they offer excellent strength-to-weight ratio and ease of fabrication.
Key Features & Technical Specifications
Compliance: Manufactured strictly to DIN EN10210 (hot-finished structural hollow sections) with EN 10210-2 tolerances.
Material Grade: Available in carbon steel grades such as S235JRH, S355J2H, and S275J0H, ensuring excellent weldability and toughness.
Surface Finish: Hot-dip galvanized coating (minimum 85 µm, per EN ISO 1461) for exceptional corrosion resistance in outdoor and harsh environments.
Dimensional Range: Square sections from 20×20 mm to 400×400 mm, wall thickness from 1.5 mm to 16 mm, and lengths up to 12 m (custom lengths available upon request).
Mechanical Properties: Yield strength ≥ 235 MPa (for S235JRH), excellent impact resistance at low temperatures.
Fabrication: Easy to cut, weld, drill, and form, suitable for trusses, pillars, handrails, and architectural frames.

Frequently Asked Questions (FAQ)
Q: What is the difference between DIN EN10210 and EN10219?
A: DIN EN10210 covers hot-finished structural hollow sections, while EN10219 covers cold-formed sections. Our product is hot-finished, offering better dimensional accuracy and uniform mechanical properties.Q: Can you provide custom lengths and wall thicknesses?
A: Yes, we offer custom lengths (e.g., 9 m, 10 m) and wall thicknesses within the production range. Please contact our sales team with your requirements.Q: How long does the galvanized coating last?
A: The hot-dip galvanized coating typically lasts 20–50 years in normal atmospheric conditions, depending on the environment. It provides excellent corrosion protection without maintenance.Q: Are these tubes suitable for load-bearing structures?
A: Absolutely. They are designed for structural applications such as columns, beams, trusses, and bracing. The DIN EN10210 standard ensures high yield strength and toughness.Q: What certifications do you have?
A: Our factory is ISO9001 certified. We also comply with HACCP, SA8000, and other management systems. Specific product certificates (e.g., EN 10210 compliance report) can be provided with each shipment.Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, the MOQ is 5 tons. For custom sizes, MOQ may be higher. Please inquire for details.Q: How do you pack the tubes for export?
A: We use steel strapping, waterproof paper, and plastic caps to protect the ends. Tubes are bundled securely for container loading. Custom packaging is available upon request.Q: Can you arrange third-party inspection?
A: Yes, we can arrange inspection by SGS, BV, or other accredited agencies at the buyer’s cost. Our QC team will also provide mill test certificates.
