MegaDome DB Series Permanent

The DB series is MegaDome's permanent flagship — a fully custom, truss-arch engineered fabric building where every arch, sidewall assembly and foundation is designed for the specific site. This is the profile Building Depot specifies for municipal salt domes, 80×200 horse riding arenas, dairy free-stall barns, aggregate storage, salt-and-sand facilities and large commercial warehouses.

DB accepts four MegaDome arch profiles — XL, XP, HP and XXP — so the engineering team tunes the arch geometry to the exact snow, wind and equipment-clearance requirements of your site. Sidewalls can be full concrete push-wall, precast panel, insulated stud wall or a hybrid combining permanent masonry below with the fabric arch above.

Clear spans reach 160 ft with no interior columns. Every DB build ships with sealed Ontario engineering, hot-dip galvanized steel frame and heavy PVC membrane. Typical on-site install is 3 to 6 weeks after foundation completion, so even at 160 ft clear span you avoid the schedule of conventional structural steel.
