Euro Underground Pile

Product Overview

We specialize in manufacturing heavy-duty JCOE large-diameter welded steel pipes, with European standard underground pipe piles as our flagship product line.

Euro underground pipe piles are engineered in full compliance with EU industrial standards, mainly fabricated from S355J0H structural steel. The material delivers a minimum yield strength of 355MPa and maintains impact energy above 27J at 0°C, fully satisfying rigorous mechanical and low-temperature performance demands of underground infrastructure. We supply two forming options: cold-formed welded hollow sections and hot-rolled tubular pile blanks. These pipe piles act as load-bearing partition components in underground tunnels and passages, capable of enduring persistent soil compression and underground water pressure.

Differences Between Euro Underground Pipe Piles & Ordinary Foundation Piles

Material Performance

Euro underground piles adopt EN 10219 S355J0H cold-formed hollow steel tubes, featuring yield strength ≥355MPa and stable low-temperature impact resistance at 0°C, meeting strict cold-region engineering standards. Common foundation piles mostly use basic Q235B carbon steel with much looser mechanical property requirements.

Anti-Corrosion & Certification

European standard pipe piles require full CE certification, with controlled carbon content below 0.40% to guarantee stable weldability and long service life underground. Conventional foundation piles have no mandatory anti-rust certification rules.

Application Scope

Euro pipe piles are designed for tunnel support frames and underground passage partition structures under combined water and soil load. Regular foundation steel pipes are only suitable for ground building foundation reinforcement projects.

Core Advantages of Euro Underground Pipe Piles

High structural strength

Even deployed in cold climate zones, the pipe pile maintains long-term structural stability without deformation or cracking.

Excellent anti-corrosion performance

Hot-dip galvanized surface treatment effectively resists underground soil corrosion, greatly extending service lifespan under humid buried conditions.

Precision pipe jacking construction

Compatible with mature pipe jacking construction technology, ground settlement can be precisely controlled within millimeter tolerance, perfectly fitting complex geological environments in dense urban areas.

Strong load-bearing capacity

The maximum bearing capacity reaches 1500kN. By coordinating force bearing with surrounding soil or internal grouting reinforcement, it greatly enhances the stability of weak foundation layers.
