Caledon project — equipment garage

We completed a turnkey pre-engineered metal building for a client in Caledon, Ontario — an equipment garage approximately 50×40 ft. Scope included full steel frame assembly, insulation with vapour barrier, metal roof panels, and insulated wall cladding. The building was completed in one continuous construction sequence with our own crew.

Why pre-engineered metal buildings

• Faster construction than conventional wood or concrete — most buildings complete in days, not months
• Lower cost per square foot than conventional construction
• Engineered for Ontario snow and wind loads — building kits come with engineering stamps
• Expandable — most PEMB systems allow future extensions
• Low maintenance — steel structure and metal cladding require minimal upkeep
• Available in any size from small garages to large industrial facilities

Standing seam upgrade

Standard PEMB kits come with R-panel (exposed fastener) roofing. We offer a standing seam upgrade — concealed fastener system, 50+ year lifespan, no exposed screws. For clients who want a premium building envelope, standing seam on a PEMB structure is the correct long-term choice.
