Every Building Depot series shares the same pre-engineered, site-specific approach. Building Depot configures the right series, profile and clearance for your Ontario project.
Temporary or permanent modular domes — solid, adapted to punctual needs and smaller projects. Simple, fast installation. Engineered for industrial, municipal and agricultural use.
Truss-arch permanent dome spanning 33 ft to 160 ft clear, with wide interior clearance and five profile options. Hot-dip galvanized steel, oval tubes for optimized resistance, and length extendable as your operation grows.
Custom-engineered permanent structure designed per project — up to 200 ft wide with vertical walls for maximum clearance. Truss arches are always hot-dip galvanized. Roof membrane can be replaced per section and the building can be extended as your business grows.
When your operation needs unobstructed interior space — for stockpiles at full angle of repose, for the swing of a front-end loader, or for stacking trucks bumper-to-bumper — Building Depot engineers a large-span Megadome that gives you the full footprint with zero interior columns. Permanent, hot-dip galvanized, and sized to your equipment.

Every Building Depot dome is configured around how product, equipment and people move through the building. Two of the most common options we engineer in Ontario:
A full-height sliding or bi-parting side door cut into the sidewall — engineered to fit loaders, tandem trucks and end-dumps without losing the gable-end stockpile depth. Framed in hot-dip galvanized steel, insulated cladding optional, and integrated into the structural arch so the dome rating is preserved.
Most aggregate, salt, sand and bulk-material buildings are filled by a stacker or radial conveyor. We engineer a dedicated conveyor opening — gable-end or sidewall — sized to your belt geometry, drop height and stockpile angle of repose, so you fill the dome to its full clear-span volume.
Other options — overhead doors, man-doors, ridge & gable ventilation, insulated liners, lighting packages — are quoted per project. Tell us how the building has to operate and Building Depot engineers the openings around it.
