Can you handle custom or oversized commercial installs?

Here is what makes a large install different and how we approach it.

What makes custom oversized commercial doors different

The challenge in a big door is weight and balance. A door that spans a wide, tall opening can weigh many hundreds of pounds, and every part of the system has to be sized for it:

• Springs. The counterbalance has to be calculated for the exact door weight and the cycle volume, often with high-cycle springs so the door does not need frequent service.
• Track and lift type. Tall ceilings allow high-lift or full-vertical-lift hardware that stores the door higher and clears more headroom, but each needs its own track geometry.
• Operator. A large door needs a commercial operator with the torque to move the weight and the controls to do it safely.
• Structure. The header, jambs, and backing have to carry the load, which sometimes means coordinating with the building.

Get any of these wrong and the door feels heavy, runs rough, or wears out fast. Sizing the whole system to the opening is the entire job.

Openings we build for

Custom and oversized work covers a range of buildings:

• Industrial and manufacturing bays with wide, tall openings for large equipment.
• Fire stations and fleet garages that need fast, reliable doors on big openings.
• Agricultural and storage buildings with extra-wide spans.
• Buildings with high ceilings where high-lift or full-vertical-lift hardware makes the most of the headroom.
• Openings needing a code rating, where the custom door also has to be a listed fire-rated assembly.

When a large opening also has to meet a fire separation requirement, the door has to be both correctly sized and a listed assembly. We cover that side in our guide to fire-rated commercial doors.

How a custom install goes

A custom job starts with measurement and load, not with a catalog. We measure the opening, the headroom, the side room, and the backing, then calculate the door weight and the spring and operator spec from there. We confirm the lift type the ceiling allows, order the door and hardware built to those numbers, and install with the structure and the operator matched to the load. Before we leave, we balance the door and cycle it to confirm it runs smoothly and the safety devices work the way code expects.

That sequence is what separates a custom install from a forced fit. A door specified to the real opening lasts and runs quietly; a door crammed into an opening it was not sized for becomes a service problem.

A few details make or break a large install, and they are the ones a stock approach skips:

• Headroom and lift type. The space above the opening decides whether the door uses standard, high-lift, or full-vertical-lift hardware, and each needs its own track radius and spring math.
• Side room. The space beside the opening has to fit the track and the springs, which on a wide door is not a given.
• Backing and reinforcement. A heavy operator and the door's load need solid backing at the header, which sometimes means adding structure before the door goes in.

Getting these right up front is far cheaper than discovering mid-install that the opening cannot take the door as drawn.

We take on the large and non-standard installs across the Denver metro and the Front Range that need engineering rather than a stock part, with flat-rate quotes and free estimates on commercial work. To compare the door families a big opening might use, see our overview of commercial garage door services. Tell us the opening width and height, the ceiling clearance, and how the door will be used, and we will design and install a door built to your building.
