MegaDome AR Series 200 ft Span

The AR series is MegaDome's fully custom, truss-arch engineered fabric building — the profile Building Depot specifies when clear span exceeds 130 ft, when push-walls approach 16 ft, or when the arch geometry itself has to be designed around a specific process, conveyor, aircraft or piece of equipment.

Every AR project starts as a blank sheet in the engineering office. Arch depth, connection design, sidewall assembly and foundation are all custom to the site. That flexibility is why AR is the standard for large aggregate stockpile cover, primary and secondary crusher enclosures, wide-body aviation hangars, large indoor sports facilities and heavy industrial process cover.

AR clear-spans reach 200 ft with no interior columns. Sidewalls integrate 12, 14 or 16 ft precast push-walls, insulated masonry, or full-height wind walls as required. Every AR build ships with sealed Ontario engineering, hot-dip galvanized steel truss frames and heavy PVC or PE membrane options tuned to the exposure.
