PRODUCT
Tianjin Brisk Steel focus on produce and supply hollow section and steel pipe
ecoding the EN 10219 S355J0H Designation
For global procurement managers and structural engineers, decoding the European standard nomenclature ensures exact material alignment:
- EN 10219: The European standard for cold-formed welded structural hollow sections of non-alloy and fine-grain steels.
- S355: Denotes a structural steel ("S") featuring a minimum yield strength of 355 MPa, providing an optimal strength-to-weight ratio.
- J0: Specifies the impact verification energy-guaranteed to withstand a Charpy V-notch impact test of 27 Joules at 0°C, ensuring excellent material toughness in cold weather.
- H: Stands for "Hollow Section."
- LSAW (Longitudinally Submerged Arc Welding): The production methodology where heavy-gauge steel plates are progressively formed into a cylinder and welded along a single, straight longitudinal seam using automated double-sided submerged arc welding.
Primary Structural Applications
- Deep Foundation Piling (Bridge piers, marine terminals, port foundations)
- Offshore Engineering (Wind turbine foundations, jacket structures, platform braces)
- Civil Infrastructure (Airport terminals, mega-stadium roofs, structural arches)
- Heavy Machinery Manufacturing (Crane booms, chassis frames, material handling masts)

| Wall Thickness (WT) | 6 mm up to 60 mm |
| Minimum Yield Strength (Re) | 355 MPa (for wall thicknesses 16 mm) |
| Tensile Strength (Rm) | 470 - 630 MPa |
| Impact Energy (Charpy V-Notch) | Minimum 27 J at 0℃ |
Frequently Asked Questions (FAQ)
Q: Why choose S355J0H over S355JRH?
A: The distinction lies in the temperature at which impact toughness is verified. S355JR is tested at room temperature (20℃), whereas S355J0H is certified to maintain its impact energy absorption down to 0 ℃. This makes J0H significantly safer for outdoor structures in regions that experience freezing winter conditions, preventing sudden brittle fractures.
Q: What quality control tests are applied to the LSAW weld seam?
A: Every pipe undergoes a strict sequence of Non-Destructive Testing (NDT), including 100% continuous Ultrasonic Testing (UT) along the longitudinal weld, Radiographic (X-ray) Inspection of the pipe ends and joint intersections, and a mandatory Hydrostatic Pressure Test to verify complete seal and joint integrity under load.
Q: How are the pipes protected against corrosion during maritime transit?
A: To prevent atmospheric rust during international ocean transport, the pipes are treated with a temporary external anti-rust black varnish or light oil coating. For long-term protection in underground or underwater deployments, we offer advanced multi-layer coatings including 3LPE (Three-Layer Polyethylene) and FBE (Fusion Bonded Epoxy).
Q: How does your factory handle the customized nesting or marking of multi-length piling pipe orders for large marine ports?
A: We understand that marine piling projects require staggered lengths (e.g., precise variations of 11.5m, 11.8m, and 12m sections). We provide precise, custom factory cut-to-length services to within +/- 5 mm. To streamline your port logistics, every pipe is clearly stenciled with its exact length, weight, heat number, and matching project color bands, allowing your field operators to organize and erect the piling grid directly from the transport vessel.
