Supplementary Support

Product Code Prefix ARCH

Overview

• Structural steel arch supports can be employed for ground control when rock bolting is not practical or where other ground support applications are insufficient, particularly where strata is unstable or loading is too severe for other supports. Steel arches can provide a more low cost permanent support solution for long term critical requirements such as permanent travel ways in decline development, conveyor drifts and portals.
• DSI Underground steel arch support design configurations are tailored to suit your specific site requirements with consideration to clearances, load capacity, erection, handling and assembly.
