ASTM A252 Gr.2 and Gr.3 LSAW pipe piles
ASTM A252 is the standard written for welded and seamless steel pipe piles, so it is the most common specification, such as ASTM A53 Gr.B, ASTM A500 Gr.C, JIS G3444 STK490, API 5L Gr.B, ISO 3183 L245, and GB Q355B for port, bridge, and infrastructure foundations. We supply ASTM A252 Gr. 2 LSAW pipe and ASTM A252 Gr. 3 LSAW pipe.
| Grade | Min. yield strength | Min. tensile strength |
| Gr.2 | 241 MPa (35 ksi) | 414 MPa (60 ksi) |
| Gr.3 | 310 MPa (45 ksi) | 455 MPa (66 ksi) |
A252 sets mechanical and dimensional requirements and limits phosphorus to 0.050% max. Gr. 3 allows a thinner wall for the same load or higher driving capacity, while Gr. 2 is the economical choice for general foundations. Your piling designer should select the grade based on load and driving analysis.

EN 10219 covers cold-formed welded structural hollow sections. S355J2H is widely specified for offshore jackets, structural tubulars, and Eurocode projects, such as ASTM A53 Gr.B, ASTM A500 Gr.C, JIS G3444 STK490, API 5L Gr.B, ISO 3183 L245, and GB Q355B.
| Property | S355J2H |
| Min. yield strength | 355 MPa (wall up to 16 mm; slightly lower for thicker walls) |
| Tensile strength | 470 – 630 MPa |
| Impact energy | 27 J at −20°C |
| Chemistry (typical limits) | C ≤ 0.22%, Mn ≤ 1.60%, Si ≤ 0.55%, P and S ≤ 0.030% (confirm against the current edition of the standard) |
We also supply EN 10219 S235, S275, and S355JRH grades. EN 10219 covers cold-formed welded structural hollow sections. S355J2H is widely specified for offshore jackets, structural tubulars, and Eurocode projects, including ASTM A53 Gr. B, ASTM A500 Gr. C, JIS G3444 STK490, API 5L Gr. B, ISO 3183 L245, and GB Q355. B.

Large diameter LSAW pipe piles: 1020 mm, 1220 mm, 1420 mm, and above
Typical foundation piles have outside diameters of 1020, 1220, and 1420 mm, and we produce up to 4,000 mm. We form thick walls up to 50 mm from a single plate, ensuring accurate roundness and a straight longitudinal seam. This is why LSAW is preferred for heavy driving, deep foundations, and marine structures.
Beveled ends, piling shoes, and field splicing
We normally join long piles on site by butt welding. We prepare beveled ends for your weld procedure and fit piling shoes for tough ground or rock. State your splice detail and driving conditions when you inquire.
Coating and corrosion protection
Choose the coating based on the environment and design life.
- 3PE / FBE / epoxy: buried and immersed sections
- Bitumen, zinc, or anti-corrosion paint: atmospheric and splash zones
- Cement mortar: specific project requirements
- Bare pipe + cathodic protection: common for marine piles
Applications
- Jetty, port, and quay foundations
- Bridge piers and abutments
- Offshore platform and jacket piles
- Wind energy foundations and structural tubulars
- Onshore deep foundations for plants, storage tanks, and high-rise buildings

Quality control and inspection
- Plate and raw material checks with mill certificates
- Forming, tack welding, and submerged arc welding (inside and outside)
- Weld NDT: ultrasonic and radiographic testing
- Dimensional, roundness, and wall thickness inspection
- Mechanical tests to the specified standard
- Final visual inspection, marking, and documentation
We provide an EN 10204 3.1 mill test certificate with each shipment. We can arrange third-party inspection by SGS, BV, or TUV for your project.
Packing and shipping
We supply pipes with end protectors, lashed in bundles or loose for large diameters. We normally ship the steel pilings larger than about 1,200 mm as break bulk, while smaller sizes can be shipped in containers. We quote FOB, CFR, and CIF to ports in the Middle East, Southeast Asia, Africa, Latin America, and Europe.

Frequently asked questions
What is SAWL piling pipe? SAWL stands for Longitudinal Submerged Arc Welded Pipe. A steel plate is formed into a cylinder and welded along its length by submerged arc welding. SAWL piling pipe is used as foundation piles for ports, bridges, and offshore structures.
What is the difference between ASTM A252 Gr. 2 and Gr. 3? Gr. 2 has a minimum yield strength of 241 MPa, and Gr. 3 has 310 MPa. Gr. 3 allows thinner walls or higher driving stress for the same section, while Gr. 2 is more economical for general foundations.
Is EN 10219 S355J2H suitable for pipe piles? Yes, when your project specification calls for it. S355J2H has a 355 MPa yield strength and a 27 J impact requirement at −20 °C, and it is commonly used for offshore jackets and structural tubulars. For port and bridge piles, ASTM A252 is more common.
LSAW vs SSAW: Which is better for piling? LSAW is made from a single plate and suits large diameters and thick walls up to 50 mm with a straight seam. SSAW is spiral-welded from coil and is often chosen for lighter onshore piles. For heavy driving or marine work, LSAW is usually preferred.
What sizes can you supply? Outside diameter: 457–4,000 mm; wall thickness: 8–50 mm; length: 5.8–18 m. Common pile sizes are 1020, 1220, and 1420 mm.
What documents and inspections do you provide? We provide an EN 10204 3.1 mill test certificate, dimensional and visual reports, and weld NDT records. We can arrange third-party inspections with SGS, BV, or TÜV.
Which coating is suitable for marine piles? Common choices include 3PE, FBE, epoxy, coal-tar coatings, or bare pipe with cathodic protection. The right system depends on the splash zone, soil conditions, and design life.
How do you ship large pipe piles, and what are the MOQ and lead time? Large-diameter piles are typically shipped in bulk and come with end protectors. MOQ is 25 tons, and lead time is about 3-4 weeks after order. We quote FOB, CFR, or CIF.
Do I need to consider EU CBAM or US duties? Steel imported into the EU is subject to CBAM reporting from 2026, and US-bound steel may face additional duties. Rules change often, so please confirm your current position with your customs broker and share your destination when you request a quote.
