How a Garage Door System Works

How Do Garage Doors Work?

Most people use their garage doors several times a day. This comes out to 1,500 times per year. If you’ve never had garage door problems, you’re probably unfamiliar with exactly how a garage door system works. Understanding the mechanics, parts, and operations of your garage door system can help you determine when you need a garage door repair or replacement. In this article, our Sacramento garage door experts share how the typical garage door system works.

Components of a Garage Door System 

The best way to better understand how the garage door system works is by learning about all of the parts and components. Most houses feature a sectional overhead garage door, which is composed of galvanized steel, fiberglass, aluminum, or wood and glides along a track utilizing rollers mounted on the garage ceiling. A curved arm connects the door to a garage door opener to assist with movement. The garage door motor directs the movement of the door open or closed as prompted, using the torsion spring system — or extension springs — to counteract the weight of the door, allowing safe and steady mobility.

System of Garage Door Hardware

While the operation of your garage door system appears straightforward, multiple pieces of hardware operate in tandem to provide dependable and smooth performance. Garage door parts are composed of high-quality galvanized steel for long-lasting strength, durability, and performance. These parts’ thickness is measured in gauges, with lower numbers signifying thicker steel. Learn about the main components of your garage door system so you can continue keeping your garage door in top shape.

Garage Door Springs:

Most garage doors employ either a torsion or extension spring system, with torsion springs being the more preferred option nowadays. This is because of their superior quality, safety, and longer lifespan. Additionally, torsion springs are enormous springs put on the garage door’s top that wound and unwind in a regulated activity to open and close the door while sliding into a channel. Extension springs are two springs that are situated on either side of the garage door. Torsion springs typically last up to ten years. However, extension springs are only safe to use for up to seven years.

Cables:

Made of braided steel wires, the cables function alongside the springs to lift and lower the door. The size and weight of your garage door dictate the thickness of its wires.

Hinges: 

Installed on garage door panels, hinges allow the sections to bend and retract as the door opens and closes. Larger garage doors should have double hinges to help keep the door open while it is closed.

Tracks: 

To help with movement, your garage door system includes both horizontal and vertical tracks. Additionally, thicker steel tracks ensure your garage door can withstand more weight and resist twisting and warping.

Rollers: 

Your garage door employs steel, black nylon, or reinforced white nylon to roll along the track. The use of nylon provides for a quieter operation. Furthermore, when properly cared for and greased rollers will effortlessly roll along the track and will not slip.

Reinforced Struts: 

The struts support the weight of double garage doors when they are open for long periods of time.

Weatherstripping: 

Located between the door sections, on the external frame, and along the bottom of the garage door, weatherstripping is responsible for ensuring energy efficiency and insulation as well as preventing outside factors such as moisture, bugs, and trash from entering your garage.
