Is Building Depot an authorized MegaDome dealer?

What warranty does Building Depot offer?

MegaDome fabric membranes carry a 15-year prorated warranty, and hot-dip galvanized steel frames are engineered for a 50+ year service life. Foundations and installation carry a 1-year workmanship warranty.

How wide is the MegaDome S100 series?

MegaDome publishes the S100 series in 100 ft, 125 ft, 140 ft and 160 ft widths, with lengths customized to the project. It is MegaDome's large clear-span double-truss range, above the 33–100 ft HP · XP · XXP double-truss buildings.

What truss profiles does S100 use?

MegaDome lists 33-inch and 58-inch truss profiles. The 100 ft and 125 ft buildings use the 33-inch profile; the 140 ft and 160 ft buildings are available in 33-inch or 58-inch profiles. MegaDome states interior peak clearances exceeding 53 ft on the 58-inch profile.

Is S100 suitable for aircraft hangars and large equipment?

MegaDome positions S100 for large-scale grain and commodity storage, heavy-equipment maintenance bays, indoor riding arenas, mining facilities and major industrial operations. Hangar suitability depends on the aircraft envelope and door design, confirmed in the project engineering.

What foundation does S100 need?

Foundation type is selected per site — concrete piers, grade beams, walls or slab-on-grade — and confirmed in the stamped engineering package for your loads and soils.

Where can I verify these figures?

Widths, truss profiles and clearances on this page are taken from MegaDome's published S100 page. Final dimensions, loads and clearances for your building are confirmed in the project engineering drawings.

LARGE CLEAR-SPAN FABRIC BUILDING

When your operation outgrows 100 ft.

The S100 series is MegaDome's upper range: double-truss structures from 100 to 160 ft wide. MegaDome lists the 100 ft building as the entry point, the 125 ft as one of its most specified widths for agricultural and industrial operations, and the 140 ft and 160 ft buildings for indoor arenas, large maintenance facilities, aggregate storage, grain terminals and mining.

Below 100 ft, the HP · XP · XXP double-truss buildings cover 33 to 100 ft. Building Depot handles the Ontario side of an S100 project end-to-end — site and load review, engineering, foundation, installation and service.
