Structural Ground Support

Square Sets, Arches, and Tunnel Rings for Challenging Underground Conditions

GMS supplies and installs structural steel ground control systems — including square sets, steel arches, and tunnel rings — to reinforce wide headings, poor ground, and long-term development areas. These systems are engineered for durability and load-bearing performance, offering critical support in areas where conventional bolting or cribbing may not be sufficient. Our field teams work closely with site engineers to fabricate, deliver, and install the right configuration for your mine’s conditions and layout.
