Piling steel pipe products are widely used in wharf, natural gas pipeline, petrochemical, mining, electric power, coal chemical, marine engineering, infrastructure engineering, steel structure and water supply and other fields.

Huangshangyou Iron and Steel provides piling steel pipes, spiral steel pipes, sewage shaft steel pipes, piling steel pipes for civil foundation engineering, sea reclamation piling pipes, bridge steel pipe piles, construction steel pipe columns, steel pipe piles, etc., and stainless steel pipes for construction projects. And supporting the supply of 3LPE/3LPP, polyurethane, asphalt, and other forms of anti-corrosion steel pipes, welcome to inquire.

1. Large vertical bearing capacity.
2. High bending strength, piling steel plate has high section stiffness and bending strength, and can resist considerable horizontal force in earthquakes.
3. The cross-sectional area of the pile is small, the excavation is less, and the vibration and noise are reduced.
4. It can be customized to adapt to various structures.
5. It is convenient to connect with the superstructure.
6. Light and strong, easy to handle and transport.

1. 406mm~1829mm (wall thickness 16mm-72mm) large straight seam double-sided submerged arc welded pipe (SAWL)
2. 114mm~762mm (wall thickness 4mm-30mm) straight seam high frequency welded pipe (HFW)
3. 219mm~3000mm (wall thickness 8mm-90mm) spiral submerged arc welded pipe (SAWH)
4. 610mm~2500mm (wall thickness 24mm-90mm) three-roll forming welded pipe
5. 406mm~2000mm (wall thickness 16mm-60mm) stainless steel welded pipe
