4 Must-Have Features for Every Roll-up Door

When your customers are investing in commercial roll-up doors, they want a product that will look good and operate well for years to come. No matter it's end application, whether that's a small workshop or a large industrial facility, it's also important that these doors are quick and easy to install, operate and maintain. With that in mind, there are certain features that you can look for in commercial roll-up doors to check off these boxes and satisfy your customers. That's why we're outlining the 4 major features every commercial roll-up door should have and why.

1. Dead-Axle

The dead-axle roll-up door is known for its durability and smooth operation. This is because it has a fully enclosed barrel that protects the door's springs and strengthens the entire axle assembly. The dead-axle assembly remains stationary when the door is operated, rather than turning with the door. It eliminates axle push and shift that could otherwise occur in a live-axle door and it allows for a straighter travel path of the door curtain in the guides. The dead-axle design also allows fine tuning of any spring adjustment to equally affect all springs on the door at the exact same time.

2. Enclosed, Factory Lubricated Springs

When springs are coated with grease in the factory, that grease penetrates the innermost pores of the spring with additives which displaces moisture and prevents the formation of rust and corrosion. In addition, this process relieves the friction created between spring coils which provides a smoother door operation. This means, no more regularly maintaining and re-lubricating your door's springs to keep them operating in optimal condition - dead-axle roll-up doors are virtually maintenance free. By placing those factory lubricated springs inside of the barrel assembly, they're protected from harmful environmental elements that would otherwise be encountered throughout the door's lifetime. Ultimately, this helps your door operate better and last much longer than live-axle doors.

3. Tension Holding Device

One of the most common reasons for door maintenance involves the door's springs. This is because the springs can relax over time, requiring adjustment to their tension. It's important to note that all adjustments made to spring tension should be completed by a certified door technician, as the tension on the spring could result in significant injury if not performed properly. Because adjusting the spring tension is a common task, it's important to find a roll-up door that has a simplified method of spring tensioning, such as a ratchet tensioning device or a cam-action spring tension holding device. These devices offer a simpler method of spring tensioning while more accurately fine tuning all the springs on the door at the same time. 

4. Durable Curtain

The curb appeal of a commercial building is very important. Your customers don't want a door that is going to quickly chalk, chip or fade, as this hurts the aesthetics of their building. Once a door's curtain does chip, chalk or fade, there isn't a long-term solution other than replacing the door. That's why it's so important to offer your customers roll-up doors that have durable curtains, available in a variety of color options and that are backed by an impressive paint warranty protecting its integrity from aging elements.

When you invest in a dead-axle roll-up door that has enclosed factory lubricated springs, a tension holding device and a durable curtain, you can satisfy your customers by offering them a commercial door that will look it's best and operate well for years to come.
