Advantages and types of Automatic Doors

An automatic door opens automatically using an in-built sensor system. The sensor controls the opening and closes the door automatically upon receipt of a momentary actuating signal.

The sensors are placed on the top and sides of the door frame. When these optic or motion sensors sense motion nearby, they trigger the automatic doors to open and then close. Automatic doors come with varying ways of customization. These doors are designed and factory-made using state-of-the-art and technology for frequent use with high opening speeds.

The easy accessibility and safety are two of the important factors leading to its demand. The high opening speed reduces time taken in movement of material, thus hastening the logistics process. Many manufacturing industries nowadays need a controlled environment in which you maintain a hygienic environment in the manufacturing premises. Automated doors have become an integral part of different industries. A wide range of automated doors are available for various operations, including areas with special requirements for temperature control, hygiene, storage and handling of frozen foods etc. Companies are focusing on leveraging advanced technologies to offer high-quality products to meet the evolving demands of the end-users.

Types of automatic doors 

The latest high-performance industrial doors are designed to be able to withstand equipment impact and come with features such as automatic breakaway in case of any accidental hit by a vehicle.

Given below are different types of automatic doors used across industrial and commercial applications.

Roller Shutter doors

A roller shutter consists of an array of horizontal slats or bars that are hinged together and can operate in a vertical plane within a frame. Operation is automatically operated that can be controlled using the remote control, photocell, induction loop or motion sensor triggered access. Roller Shutter Doors are often used for access to warehouses or business units where security, protection from the environment and ease of access is required.

Sectional overhead doors

The key feature of these doors is that it is made using composite materials, which gives them high opening speeds. Operated by powerful motors, a guiding system allows for the smooth operation of high-performance industrial doors. In many instances, these doors are also designed for easy docking of vehicles. The sectional overhead industrial doors are also usually designed to achieve sound insulation.

Sliding doors

Sliding doors, both the horizontal and the top hung types are also popular these days. Depending on the type of industry they are used they can be designed in different forms. In several industries, telescopic sliding doors with several panels are also becoming popular choices. Automatic Swinging Doors are usually directional and used for one-way traffic, either in or out. Automatic swinging doors can be single, pair, or double doors.

Automated swing doors

These are made of a special material that helps keep the interior either cool or heated to a certain limit. They are usually the choice when it comes to indoor applications in warehouse industries.

PVC Strip Curtains or Crash Doors

These Crash doors are purpose-built for providing ease of access to fork lift trucks, trollies, vehicles or personnel through the controlled access point without the need for stopping and opening/closing the doors either manually or via some sort of switch.

Swing doors

Swing doors are designed for high-traffic retail applications. All doors are high impact, lightweight and easy to clean. Their strong, hard-wearing and long-lasting construction require minimum maintenance. The smooth, non-porous gel coat finish makes them easy to clean and resistant to water and cleaning chemicals. These Doors come fitted with polypropylene bumpers to guard against aggressive traffic and prevent damage to the door face.

High-Speed doors

High-Speed Doors are designed to save energy and create better working conditions where fast action is required. The door’s smooth rapid action, counterbalanced system, strong durable door panel and full-width vision panel make them ideal for industrial environments. The vertical guides of these doors incorporate seals to prevent draughts and the ingress of dust, insects, and vermin. The door can also be manually opened in case of an emergency.

Automatic Revolving doors and Manual Revolving doors (rotating doors)

These are used in high-traffic areas and provide pedestrians the ability to enter and exit simultaneously. They allow a large number of people to pass in and out at the same time. Revolving doors are energy efficient. The doors can have two wings, three wings, and four wings that are usually made of glass.

Automatic Folding doors

These are usually installed when space is a consideration. Automatic folding doors can be single-fold or bi fold doors, and pedestrians can move in either direction through the same opening.

Fast Action doors

The fast action or dynamic door is a rapid roll door with an opening speed that can be defined to your requirements. This means that this type of door is perfect for high-traffic areas opening quickly giving you smooth traffic management.
