The Challenge

A heavy industrial warehouse in Mississauga with red steel beam framing and high-bay ceilings needed a large commercial insulated sectional overhead door — and the building’s height made standard track configurations unsuitable. Standard radius track on a large sectional door requires sufficient clearance above the opening for the door panels to transition from vertical to horizontal travel, and in a high-bay building with ceiling infrastructure, that transition geometry needs to be engineered specifically for the available space. Getting it wrong means a door that can’t fully open without impacting overhead structure, or a counterbalance specification that fails prematurely because the door’s weight distribution wasn’t properly calculated for the track geometry.

The Solution

Wilcox Door Service surveyed the warehouse’s steel framing, ceiling height, and available headroom above the opening before specifying the track configuration. A custom track layout was engineered to suit the building’s available headroom and structural anchor points, ensuring the door could travel through its full range without interference with the overhead beam framing. The counterbalance system was calculated for the door’s actual weight in the high-lift configuration — a calculation that differs from standard radius track and requires accurate door weight data and track geometry to get right.

The white insulated steel door panels were specified for the opening dimensions and the thermal performance requirements of the warehouse, with hardware — springs, hinges, rollers, and operator — sized for the door’s weight and the cycle frequency of the application.

Outcomes

The door travels through its full range without impacting overhead structure, operates smoothly with the custom counterbalance specification, and provides the insulation performance the warehouse requires. The track geometry was engineered to work in the actual building rather than against a standard template, and the result is a door installation that operates correctly from the first cycle and will continue to do so throughout its service life. The facility has the large-format insulated door it needed in a space that required real engineering to deliver it.
