A finished steel interior adds rigidity, durability and a more substantial appearance. The next step is deciding which design and performance choices fit your home.

More than a special-use door.
Steel-Back construction can add value anywhere the homeowner prioritizes long-term quality, a finished interior and refined operation.
Greater rigidity
Layered construction creates a stronger, more substantial door structure.
Quiet, solid feel
Correct installation and upgraded components can support smoother, more refined operation.
Premium presentation
The finished construction can strengthen perceived quality inside and outside the garage.
Inside the door
Construction and insulation choices.
Steel-Back means the insulation is enclosed between exterior and interior steel skins. Thickness and insulation are offered as specific product configurations rather than completely independent choices.

Narrow the selection
Your next four decisions.
Steel-Back identifies the construction. These choices determine what the finished door will look like and how it will serve the home.
Panel design
Short raised, long raised, flush and carriage-stamped designs create very different architectural results.
Color and finish
Coordinate the door with the trim, exterior materials and overall character of the home.
Window design
Decide whether natural light, decorative glass or a cleaner window-free appearance fits the project.
Performance package
Compare spring life, rollers, operator features, hardware finish and connected-access options.
Prepare for the estimate
Compare the right Steel-Back door for your home.
