Cambridge is a manufacturing city, and manufacturing doors are a different problem from warehouse doors. The City of Cambridge states that *"advanced manufacturing accounts for nearly 20% of the City’s workforce"* and that the city hosts *"some of the largest facilities in robotics and automation, automotive, aerospace, and nuclear industries"*. In plants like those the important doors are often inside the building, and the production line decides when they can be touched.

## What makes a manufacturing door different?

An exterior dock door fails and the bay stops. An interior door fails and the process stops, which is a much larger number. Interior doors separate a clean area from a dirty one, a conditioned area from an unconditioned one, or a robot cell from a walkway, so the door is part of the process specification rather than part of the building envelope. That is why high-speed doors are common on these openings: the door is on the critical path for every cycle, and its speed is a production figure. What the terminology on a specification actually means is set out in [DASMA Technical Data Sheet 451](https://www.dasma.com/wp-content/uploads/2024/01/TDS451.pdf).

## Where we work in Cambridge

The Highway 401 corridor industrial parks, and the older manufacturing areas in Galt, Preston and Hespeler. The 401 buildings are mostly distribution and newer manufacturing; the Galt and Preston stock is older, often multi-storey, and carries openings that were cut for a different era of vehicle.

## What we see most in Cambridge

- **Interior high-speed doors**: out of adjustment or running slow, which shows up as a production number before anyone calls it a door fault. [High-speed doors and shutters](https://www.commercialgaragedoorman.ca/services/high-speed-doors-rolling-shutters/).
- **Work that has to happen in a shutdown window**: , planned around the line rather than around our day. [Planned maintenance programs](https://www.commercialgaragedoorman.ca/services/planned-maintenance/).
- **Safety devices on doors people walk through constantly**: , where a monitored edge is not a formality. [The UL 325 rules](https://www.commercialgaragedoorman.ca/guides/commercial-door-safety-edges/).
- **Older exterior doors on legacy plants**: with hardware that has been repaired more than once. [Rolling steel door repair](https://www.commercialgaragedoorman.ca/services/rolling-steel-doors/).

## How do we cover Cambridge from Grimsby?

Cambridge is outside the same-day corridor the Grimsby base holds along the QEW, so it is covered for installations, scheduled maintenance and contract service rather than on a promised emergency window. On a plant that schedules its own downtime that tends to suit both sides: the work goes in the shutdown window, not in the middle of a shift. Emergency availability is confirmed on the call.

## What should a Cambridge plant engineer have ready?

Which doors are interior and which are exterior, what each one separates, and when the line can be stopped. That is the difference between a quote and a guess, because an interior door in a controlled environment is specified on what it is holding back, not on the size of the hole.
