DuraFuse Frames
Decrease construction cost while adding resilience to hybrid timber and steel moment frame buildings with DuraFuse Frames. Our innovative technology means the lowest steel tonnage, simple fabrication, quick frame erection, and rapid repair and re-occupancy following a major seismic event. Bolted connections eliminate field welding. The innovative connection eliminates over 2/3 of seismic braces. DuraFuse is the only prequalified seismic connection that meets all these criteria. Our engineers support your design team to provide a resilient design that is economical and rapid to build and designed for quick recovery after an event. Why use anything else? | DuraFuse Frames is the next evolution in steel moment connections. Working with our engineering team and implementing our field-bolted connection will minimize steel tonnage, simplify fabrication, and shorten the erection schedule for any project. In seismic-controlled projects, the resilience advantage is unmatched and comes with the additional benefit of eliminating lateral braces and minimizing the protected zone. Our qualification-tested connection retrofit solutions are unequaled. Let us collaborate with your team to find the optimal solution for your project.
