The roll-up sheet door is one of the most cost-effective and reliable door systems available. It offers affordable, rugged strength with little maintenance. However, complete lack of use or maintenance can damage a sheet door faster than overuse. Follow these tips to get the most out of your door and keep it “rolling” smoothly.

Grease Springs and Guide Strips

Spring
Minimal maintenance of the spring assembly ensures longer and more durable use.

Springs are the most critical mechanical component of a steel curtain roll-up door, and they do most of the work related to its opening and closing. In fact, springs are the most extended when the door is closed, and are at rest when the door is open. After thousands of cycles (a single cycle consists of one open and one close), the most common issue a door has is an improperly lubricated spring.

For ease of operation, keep the springs and rubber guide strips lubricated by applying white lithium grease annually. This lubricant can be purchase at most home improvement stores for less than $20. In self-storage applications, also apply grease whenever units change tenants—in residential use, this can be as often as every five to seven months.

Remove Dust and Dirt

Dust and dirt buildup can wear on a door and its components, as can cobwebs, pollen or any airborne debris that accumulates over time. Remember, where light can penetrate through the cracks in a closed door, so can air and dust. Regularly dust around the corners and edges of the door, either with a small broom or industrial duster.

In most regions, winter and early spring is the period of heaviest particulate buildup, so make a habit of spring cleaning to maintain performance. To remove heavier build up, use a rag with water and gentle soap. Do not use a power washer, as this can damage the curtain and displace smaller components.

Keep the Moving Parts Moving

Light use is better than non-use; springs perform best when they are used regularly. Give doors a brief open-and-close whenever possible to keep the moving parts moving and test the spring tension. As mentioned before, springs that have remained dormant can benefit from a heavy application of white lithium grease, which also prevents rust and extends their life.
