1. Seamless Steel Pipe Piles
Seamless steel pipe piles are steel pipes formed from steel billets through perforation. They feature smooth, weld-free inner walls. Seamless steel pipe piles are widely used in underground excavation, foundation reinforcement, river channels, ports, reservoirs, and other fields. Their smooth, weld-free inner walls offer excellent mechanical properties and corrosion resistance, making them suitable for projects requiring high bearing capacity and impermeability.
2. Spiral Steel Pipe Piles
Spiral steel pipe piles are steel pipes formed using a spiral winding process, resulting in a "helical" shape. Spiral steel pipe piles offer soil compaction, strong bearing capacity, and excellent seismic resistance. They are suitable for foundation reinforcement, earthquake mitigation, and rocky mountain cuttings, and are widely used in various construction projects. The installation process for spiral steel pipe piles is relatively simple, and the diameter and wall thickness of the steel pipe can be adjusted to meet the needs of different projects.
3. Tapered Steel Pipe Piles
Tapered steel pipe piles are an advanced engineering technology based on steel pipe piles, developed to address support and reinforcement issues in deep, unfavorable rock foundations. They offer excellent workability, high bearing capacity, and reusability, making them widely used in underground projects such as tunnels and underground garages. Their unique tapered design allows them to adapt to complex geological conditions and provide effective support and reinforcement.
4. Other Types
In addition to the three main types mentioned above, steel pipe piles can also be customized to meet specific project requirements, such as square and rectangular shapes. These specialized shapes can meet the specific project requirements for pile foundation shape and size.
