360° Sales-to-Service
One accountable team from first quote to post-install support — engineering, freight, install, warranty and service all coordinated in-house.
Rust-Free Bronze Silicone Welding
Megadome uses bronze silicone welding instead of conventional MIG — bonding steel at lower temperatures so the hot-dip galvanized coating stays intact. No burn-through, no rust hot-spots, no weld-line corrosion over the building's life.
Specialized Ventilation System
Engineered ridge vents, gable louvers and a translucent membrane work together to passively manage heat, humidity and air quality — keeping livestock comfortable, equipment dry and stored product condensation-free year-round.
In-House Installation Crews
Our own Ontario crews assemble every structure — from truss erection to membrane tensioning. No outside contractors required. Weeks, not months, from delivery to enclosed.
In-House Foundation Service
We design and pour every foundation in-house — piers, blocks, concrete pads and helical anchors — engineered to your soil report and stamped for Ontario building code. No subcontractor delays, no coordination gaps.
10 / 15-Year Warranty
10-year steel structure warranty (15 years on hot-dip galvanized) and 15-year roof membrane warranty.
