All About Overhead Doors

Space optimization and aesthetics are top priorities in warehouses. Traditional doors sometimes fail to meet these requirements, especially in areas with limited space. This is where overhead doors become a breakthrough solution.

This article will provide you with a comprehensive look at overhead doors, from basic concepts, detailed structure, and operating mechanisms to outstanding advantages, helping you better understand this type of door and make the most suitable decision for your space.

What is an overhead door?

Overhead doors are a type of industrial or residential door designed to open vertically and slide upwards, resting parallel to the ceiling when fully open. Unlike traditional rolling shutters, overhead doors use sturdy panels connected by hinges. When opening, these panels move along a guide rail system and rest neatly against the ceiling, occupying no floor space or space on either side of the door.

Thanks to this special operating mechanism, overhead doors are very popular in factories, car garages, warehouses with modern dock leveler systems, showrooms, or even residential houses, where space optimization and safety are needed.

Structure of overhead doors

To operate smoothly and safely, overhead doors are composed of many important parts, each with a distinct function:

Door panels (Door body)

This is the main part of the door, usually made of galvanized steel or aluminum alloy, with a PU insulation layer inside. These panels are designed to provide good thermal insulation, sound insulation, and resistance to environmental impacts. The outer surface of the panel can be powder-coated in various colors, creating high aesthetic appeal.

Guide rail system

The rail system is installed along the door frame and runs parallel to the ceiling. The guide rails are responsible for positioning and guiding the panels to move up and down smoothly without deviation.

Spring and cable system

This is the part that helps balance the weight of the entire door. Torsion springs are placed above the door, connected to steel cables. This system helps reduce the load on the motor and the user, making lifting and lowering the door easier.

Motor system

Most modern overhead doors are equipped with electric motors, enabling automatic opening and closing. The motor is integrated with a control unit and safety devices, allowing users to control the door remotely or via push buttons.

Safety devices

To ensure absolute safety, overhead doors are often equipped with devices such as:

• Safety sensors: Detect obstacles when the door is closing, automatically stopping or reversing to avoid collision.
• Safety lock: Prevents the door from being opened from the outside.
• Uninterruptible Power Supply (UPS): Helps the door operate normally even during power outages.

Operating mechanism of Overhead sectional doors

The operating mechanism of overhead doors is very smart and efficient. When you press the control button, the motor activates, pulling the cable up. Under the pulling force, the interconnected panels move along the rail system.

• First, the bottom panels slide up vertically.
• When the first panel reaches the curve of the rail, it begins to change direction, sliding into the rail section located on the ceiling.
• The subsequent panels also move in turn along a similar trajectory until the entire door is fully open and lies neatly on the ceiling.

When closing the door, this process happens in reverse. The spring system supports the motor, helping the panels move down gently and safely. Thanks to this mechanism, overhead doors provide convenience, space saving, and high safety.

Conclusion

Overhead doors are the perfect solution for spaces that need area optimization and prioritize aesthetics. With durable structure, smart operating mechanism, and superior safety features, overhead doors have become the top choice for many projects, from industrial factories to modern garages. Investing in a quality overhead door brings not only comfort but also a long-term investment, ensuring safety and enhancing the value of your living and working space.
