Plate/Coil Preparation: Cutting, edge preparation, and surface cleaning.

Forming: Precision bending via UOE, JCOE, or spiral forming methods.

Welding: Primary seam welding using Submerged Arc Welding (SAW) for LSAW/SSAW or HFW.

Sizing & Straightening: Calibration to ensure dimensional accuracy and straightness.

Heat Treatment (If Required): Normalizing or quenching & tempering to achieve specified mechanical properties.

Testing & Inspection: Comprehensive checks including hydrostatic testing, ultrasonic testing (UT), radiographic testing (RT), dimensional verification, and Charpy impact tests (especially for low-temperature applications).

High Load-Bearing Capacity: Engineered to withstand significant axial compression and lateral loads.

Excellent Dimensional Stability: Precise geometry ensures consistent driving performance and soil displacement.

Superior Weldability & Fabrication Flexibility: Facilitates easy splicing, end preparation (e.g., pointing), and attachment of driving heads or reinforcement.

Corrosion Resistance Options: Available in standard, coated (e.g., galvanized, painted), or weathering steel grades to suit soil chemistry and exposure conditions.

Cost-Effective & Versatile: A reliable and adaptable solution for a wide range of ground conditions and project scales.

Building Foundations: Support for high-rise buildings, industrial plants, and commercial structures.

Infrastructure Projects: Bridge piers, retaining walls, highway sign supports, and noise barriers.

Marine & Coastal Structures: Port wharves, offshore platforms, seawalls, and jetty piles.

Industrial Facilities: Foundations for heavy machinery, power transmission towers, and storage tanks.

Slope Stabilization & Land Reclamation: Used in soil nailing, anchoring, and ground improvement projects.

Primary Piling Standards: ASTM A252, EN 10219, EN 10210
