Tunnel Boring Machine Thick Steel Plates for Cutterhead Shields

Our TBM thick steel plates (grades S460NL, Q690E) withstand extreme abrasion and impact in cutterheads, shields, and screw conveyors. High hardness and toughness combination resists rock crushing forces. These thick steel plates offer excellent weldability for complex fabrications. Thickness 20–150mm. Ultrasonic tested. Improve tunneling progress in hard rock and mixed ground. Choose durable TBM-grade thick steel plates.
