Understanding Commercial Garage Door Springs

Springs are one of the most critical components of commercial garage doors. They store and release energy, enabling the door to open and close smoothly. There are two primary types of springs: torsion and extension springs.

Torsion Springs

Torsion springs are mounted above the door and work by twisting to lift the door. They are typically more durable and provide better balance, making them suitable for heavier commercial doors.

Extension Springs

Extension springs are located on either side of the door and stretch as the door opens. While they are often less expensive, they may not provide the same level of durability or safety as torsion springs.

The Role of Rollers and Tracks

Rollers and tracks are essential for the smooth operation of commercial garage doors. They work together to ensure that the door moves seamlessly up and down.

Rollers

Rollers provide the necessary movement along the track. High-quality rollers are made of durable materials, such as nylon or steel, and can significantly affect the door’s operation speed and noise levels.

Tracks

Tracks guide the rollers and support the door’s weight. They must be properly aligned and maintained to prevent issues such as sticking or misalignment. Regular inspections can help identify any wear and tear on tracks.

Cables: The Unsung Heroes

Cables play a vital role in lifting the door and ensuring it remains balanced. They work in conjunction with the springs, transferring the energy required to raise and lower the door.

Types of Cables

There are typically three types of cables used in commercial garage doors: lift cables, safety cables, and bottom brackets. Each serves a specific function, and proper maintenance of these cables is crucial for safe operation.

Openers: Automating Convenience

Garage door openers are essential for automating the operation of commercial doors. They come in various types, including chain drive, belt drive, and screw drive.

Chain Drive Openers

These are the most common type of openers for commercial doors. They use a chain to lift the door and are known for their durability and strength.

Belt Drive Openers

Belt drive openers offer quieter operation and are often preferred in noise-sensitive environments. They use a rubber belt instead of a chain.

Panels: The Body of the Door

Panels are the visible parts of the door and significantly influence both its aesthetics and insulation properties. They are typically made from materials like steel or aluminum.

Insulation

Insulated panels help maintain temperature control in commercial spaces, making them ideal for businesses that require climate control.

Sensors and Safety Features

Safety is paramount when it comes to commercial garage doors. Sensors, including photo eyes and motion detectors, help prevent accidents by detecting obstacles in the door’s path.

Photo Eye Sensors

These sensors project a beam of light across the door’s opening. If the beam is interrupted, the door will stop closing, preventing potential accidents.
