PRODUCT
Tianjin Brisk Steel focus on produce and supply hollow section and steel pipe
Manufacturing Process
- Manufactured in accordance with the EN 10210 standard for hot-finished hollow sections (distinct from standard EN 10219 cold-formed tubes), the S355J2H (1.0576) grade utilizes a hot-forming process that eliminates residual welding stresses. The material features a uniform microstructure and offers fatigue and vibration resistance far superior to that of cold-formed tubes.
- With a Charpy impact strength of ≥27 J at -20°C, the structure remains resistant to low-temperature brittle fracture in frigid regions (such as Northern Europe, Eastern Europe, and mountainous areas in Turkey during winter). Mechanical properties include a yield strength of 355 MPa, tensile strength of 510–680 MPa, and elongation of ≥22%, ensuring suitability for heavy-load applications and resistance to cracking during bending operations.
- Chemical composition-specifically carbon, sulfur, and phosphorus levels-is strictly controlled. The base metal and weld seam exhibit excellent compatibility, ensuring zero cracking during full-penetration field welding and making the material ideal for high-altitude on-site assembly.

Preservation & Deep Processing
- Size range: Outer diameter 219mm–2200mm; wall thickness 6mm–60mm; fixed lengths 6m/12m/18m
- Pipe end treatment: Plain end, beveled end, or beveled end with anti-corrosion edge sealing
- Standard surface finishes: Bare black pipe, black paint, hot-dip galvanizing (85μm), and FBE/3PE
- On-demand pipe wall sandblasting for rust removal, spray-marking of identification details, and stamping of standard grade information.
Applications
- Infrastructure & Public Works: Bridge tubular trusses; load-bearing frameworks for high-speed rail stations and bus terminals; columns for large-span stadium domes; main structures for elevated guardrails (EN10210 hot-finished tubular sections are mandatory for European municipal projects).
- New Energy Sector: Main sections of onshore wind turbine tower bases; pile foundations for large-scale centralized photovoltaic power plants; load-bearing bases for energy storage equipment (the wind power industry prioritizes fatigue strength and low-temperature toughness).
- Port & Marine Engineering: Dock mooring piles; main girders for trestle bridges; auxiliary support structures for offshore platforms (resistant to seawater and moisture corrosion; service life exceeds 30 years when paired with 3PE anti-corrosion coating).
- Heavy Machinery Sector: Large crane booms; bases for mining equipment; base materials for hydraulic equipment cylinders.
- Cold Climate Projects: Outdoor load-bearing structures in high-altitude, frigid regions (e.g., Russia, Northern Europe, Turkey); ensures safe and stable operation under low-temperature winter conditions.

FAQ
Q: What equivalent steel grades can replace S355J2H?
A: American standard equivalent: A572 Gr50, A618 Gr.B. Our test report data can match these standards for customers' engineering filing approval.
Q: Which inspection certificates can Brisk Steel provide for EN 10210 S355J2H LSAW pipes?
A: We supply EN 10204 3.1 mill certificate as standard. Third-party 3.2 certification by SGS, BV, TÜV is available upon request. Full test records include chemical composition, tensile test, -20℃ impact test, dimensional check and non-destructive welding inspection. CE certification is complete for European market access.
Q: How do you control pipe straightness, roundness and dimensional tolerance?
A: Products strictly comply with tolerance requirements of EN 10210-2. After welding, overall hot straightening and rounding treatment are adopted. Wall thickness tolerance is controlled within ±5%, with low ovality. Flange assembly and truss splicing do not require secondary trimming on site to save construction labor costs.
Q: Can you cut fixed lengths and process bevels as per customers'drawings?
A: Yes. Custom fixed lengths (6m / 12m / 18m or non-standard length) and V-type bevel processing are supported in our workshop. Pre-processing before delivery allows direct hoisting and welding after customers receive goods.
