Portatec Doors
Portatec's door program spans the full interior and exterior envelope, with a manufacturing depth that few suppliers in Canada can match. Every door, whether a statement entry, a patio system, or a refined interior panel, is conceived and finished entirely in-house using proprietary steel extrusion and moulding processes developed over 40 years. The result is a lineup where true custom fabrication is the standard, not an upgrade.
Entry doors are available in steel, fiberglass, and wood, with two-tone and hybrid interior/exterior finishes, arched frames, custom sidelites, transoms, and decorative glazing all part of the regular program. Portatec is the only manufacturer in Quebec producing custom steel arched doors. Patio doors follow the same material and finish logic, keeping the design language of a project consistent throughout. Interior collections round out the program with six exclusive contemporary series, each arriving fully factory-finished, pre-machined, and ready to install.
-
Exterior doors: Steel, fiberglass, wood, and hybrid combinations in virtually any size, panel layout, colour, or finish
-
Patio doors: Sliding and specialty configurations with full material and finish consistency
-

Portatec: Custom fabrication since 1984
Portatec operates from a factory showroom on the South Shore of Montreal, where every product in the lineup is designed and fabricated in-house. The brand's investment in proprietary tooling, extrusion processes, and custom moulding gives it a manufacturing depth that standard door and window suppliers simply don't offer.
​
For projects that require something truly unique, Portatec's team works directly with clients, contractors, and designers from initial specification through to installation, ensuring the finished product matches the original vision.
