Piling steel pipe is a high-strength structural foundation pipe driven deep into the ground to transfer structural loads from buildings, bridges, and marine structures to stable soil strata. Manufactured through submerged arc welding (LSAW/SSAW) processes with precise dimensional control, it offers exceptional axial load capacity and bending resistance. Key applications include skyscraper foundations, bridge piers, port wharves, and offshore platforms. With optional anti-corrosion treatments, it achieves service life exceeding 50 years in harsh environments.
