ECO Tunneling engineered profiles and panel fasteners limit panel stresses

Engineered

Connections at wall brackets, profiles, and panel fasteners are engineered to limit panel stresses associated with structural and seismic movements. 


ECO Tunneling Subframing Fire Protection System

Compliant

Our fire subframing components and systems are designed to both meet and exceed structural and fire-performance standards.

ECO Tunneling Sigma Stainless Steel Wall Bracket Tunneling Mining Products, Durasteel, Promate

Our Sigma stainless steel wall brackets and profile components have a low thermal conductivity which decreases thermal bridging.


Available in both vertical and horizontal designs Sigma brackets are available in multiple sizes to create various cavity depths. The number of fasteners back into the substructure will be optimized based on load requirements and back-up wall type.


Sigma+ brackets allow more fastener points and can be used in combination with standard Sigma brackets to address the fire panel dead loads.


Our subframing components (wall brackets, profile rails, and fasteners) are in stock and ready to be deployed for your next tunnel application.

The Cost-Effective Subframing

Our wall brackets are easy to install and are more cost-effective in labor man-hours, allowing materials to be rapidly set – especially when backup walls are not plumb or true. With our wall brackets, labor time can be cut in half.

Lifetime Material Consistency

Our subframing components do not become brittle over time like fiber-glass or plastic products. For the life of tunnel panels, our wall brackets and profiles have the stainless steel advantage.
