Ironbridge CFS Building Kits

Bridge the Gap Between Vision and Reality

Ironbridge™ delivers precision-engineered Cold-Formed Steel (CFS) kits designed to streamline your building process — from backyard ADUs and remote studios to small commercial structures and off-grid spaces.

Each kit arrives pre-sheathed, window-and-door ready, and includes all exterior finishes. You receive a clean structural shell built for resilience, while you finish the inside your way — faster, safer, and with fewer delays.
