LSAW Steel Pipe Pile ASTM A252 – Premium Foundation Solution for North American Infrastructure
Product Overview
We supply high-quality LSAW (Longitudinally Submerged Arc Welded) steel pipe piles manufactured to the ASTM A252 standard, the definitive specification for piling applications across the United States and Canada. Designed for deep foundation support, our pipes are the preferred choice for heavy civil, marine, and structural projects where load-bearing capacity and integrity are non-negotiable.
Why Choose LSAW for Piling?
Unlike spiral (SSAW) or ERW pipes, our LSAW piles utilize Submerged Arc welded process, which allows for heavier wall thicknesses and superior uniformity . This makes them ideal for "hard driving" conditions encountered in dense soils or bedrock. They deliver exceptional performance in:
◇◆◇ Bridge Foundations & Highway Overpasses
◇◆◇ Marine Terminals, Wharves, and Ports
◇◆◇ Offshore Wind and Mooring Structures
◇◆◇ High-Rise Building Deep Foundations
Specifications & Mechanical Properties
Our inventory is fully traceable to the steel mill, ensuring compliance with ASTM A252 Grade 3 (the most common grade for high-capacity projects).
● Standard: ASTM A252
○ Material: GR1, GR2, GR3.
● Process: LSAW (Longitudinal Submerged Arc Welding).
○ Out Diameter Range: 8''-72''(219-1800mm).
● Wall Thickness: Up to 50 mm (Custom heavy-wall sections available to prevent buckling during driving).
○ End Finish: Bevelled for field welding or plain end.
Quality Assurance
Every pipe is subject to rigorous inspection. We can provide EN 10204 3.1/3.2 certification and witness testing by third-party agencies (such as Lloyds, DNV, or ABS) to meet North American project specifications . Our piles are engineered to support axial compression, tension, and lateral loads, ensuring the longevity of your infrastructure.
Procurement Case & Review
In 2023, a marine contractor in Louisiana supplied 1,200 tons of ASTM A252 Grade 3 LSAW piles (36" diameter) for a port renovation project.
"We chose these LSAW piles because they handled the high driving stresses better than ERW alternatives. The wall thickness was consistent, and the bevelled ends fit perfectly with our welding schedule. All Mill Certifications were provided without delay-exactly what the engineer required. A reliable partner for critical infrastructure."
