Custom Overhead Doors

Grizzly Door Systems supplies pre-finished, insulated commercial steel doors that are custom designed from the ground up to be durable, strong, and reliable.

We offer varying thicknesses and differing insulation values, depending on your door needs. Our ranges include but are not limited to, R9 and R18. Non-insulated doors are also available, providing a low-cost and convenient option for non-heated commercial buildings, sheds, and other situations where energy costs aren’t a concern.

Our range of rolling doors come in galvanized finish, prime paint, or finished standard colours depending on your preferences. High-speed doors are crafted from fabric or vinyl, in many different colours and window designs. Additionally, there are different opening mechanisms available for you to choose from, with both manual and automated options. Types of commercial doors we provide include:

Commercial Man Doors

Man doors or “pass through” access doors provide convenience for access without having to open overhead doors or garage doors.

We can change your door slab, door frame, transom and lights. We also supply, install, and service all door accessories, such as closures, hinges, panic bars, and locksets.

We can also add a man door to your overhead sectional door if required.

Automatic Doors

We can help you make your business more accessible and therefore, more profitable.

Thanks to our selection of automatic doors. You can find a selection ranging from Barrier Free (for those with disabilities) to high speed, high cycle doors that travel at 48” per second.

If you’re worried about an automatic door getting stuck, you can be rest assured that entrapment prevention devices will reverse them if an obstruction occurs. If you need to make a more “inviting” entrance, automatic doors are the place to start.

Security and Access

Door safety is a huge priority. Motorized door systems need to be monitored and regularly inspected and maintained by experts in order to ensure the safety of all workers. Grizzly Door Systems partners with security and access suppliers to provide innovative and safety-driven overhead door solutions to help eliminate accidents and provide safe, effective door functionality.

Making your business more accessible can provide a significant advantage. We have multiple door options to choose from depending on your requirements; including aluminum, stainless steel, rubber, and more.

Loop Detectors and Air Hoses

Loop detectors (installed under the pavement) and air hoses, give a signal to open or close the door.

Motion Sensors

Motion sensors are an alternative to loop sensors for opening and closing your garage doors.

Safety Photo Eyes and Light Curtains

Photo eyes and light curtains keep you safe around your garage door. They cause the door to automatically stop or reverse if anyone or anything is in the path of the door.

Sensing Edges

A sensing edge is touch sensitive and sends a signal to start, stop, or reverse the overhead door’s motion or even ring a bell. On motorized doors, the sensing edge typically replaces the weather-seal.

Air Curtains

Air curtains inhibit air, dust, smoke, insects and odors from entering or leaving through openings while permitting unrestricted entry and exit. They seal in air conditioning and seal out hot air. The opposite is true during cold or winter weather. The average payback period from energy savings alone is approximately one year.

Air curtains and doors permit safe entry and exit to personnel and vehicles by providing full visibility through the doorway opening.
