Nov 13, 2019

Choosing a Commercial Steel Door

If you're in the commercial door business, you know how much the wrong door can affect one's productivity. This is an important decision for a buildings construction because it affects the whole operation.

A door placed in the wrong application is more likely to experience damage; A damaged door can literally halt a project, causing revenue loss in repair costs and decreased productivity due to down time.Overhead door comparison

Because doors are such an important element in a commercial environment, we're going to dive into the details to help you make the best, most educated decision when selecting an overhead door for your next project.

Sectional Doors

A sectional door is constructed of panels that retract up and over the floor space, resting parallel with the ceiling. When the door is in the closed position, you still have metal tracks and exposed parts that are attached to the ceiling. This type of overhead door is most commonly found in a garage.

The biggest benefit to sectional doors is that they have a high R-value and a low U-value in terms of insulation. This means they can be very energy efficient.


Commercial Sheet Doors

Sheet Doors on the other hand are constructed of thin sheets of steel, corrugated and locked seamed together to form one continuous curtain. Top providers use high grade steel for their curtains to ensure their door's durability. Rather than resting in a flat position parallel to the ceiling, this curtain coils up, rolling around a barrel attached to the top of a door's opening - maximizing a great deal of space.

You can utilize this extra space in a number of ways to benefit your daily operations. For example, incorporate additional lighting- we all know how poorly lit a garage can be because the lights on the ceiling have to be strategically placed to not interfere with a doors operation.

Other options for maximizing this new space are updating your HVAC system or simply gaining uninterrupted access to emergency fire-sprinklers. Your options for utilizing this ceiling space are almost limitless!

What would you want to incorporate with your extra space?

Sheet doors also come with many customizable options such as insulation (again, contributing to energy efficiency and cost savings), motor operations, vision panels, a large variety of unique colors, and more.
