Everything You Need to Know About Overhead Coiling Doors
When you begin your search for a coiling overhead door or security grille, you may be surprised to learn how many options exist. While these products provide security, they can offer so much more, fitting any need your commercial building might have. We created this guide to educate you on all your choices and help you find the best type for your building.
What Is a Coiling Door?
Coiling doors are metal slatted doors that roll up above the opening. As the door opens, it forms a compact coil. In comparison, a sectional door needs exceptional backroom, since these doors often hang parallel to the ceiling when open. Coiling doors remove many issues often associated with sectional garage doors. They don't have cables or hinges that wear out and eventually require maintenance and replacement.
Coiling roll-up doors are often used in commercial settings because they stand the test of time with less frequent maintenance. They provide a secure barrier against intruders and weather events. Doors typically come with solid slats for outdoor security and weather protection. They can also come with perforated or windowed slats for enhanced visibility and airflow. For increased visibility and ventilation, different rolling grilles give you the best air flow and view while still providing security.
Coiling doors consist of heavy-duty galvanized steel, stainless steel or aluminum, making them extremely durable. Depending on construction, some doors can withstand high-force winds, while other doors provide enhanced protection against mob-style break-ins. These doors are incredibly customizable and can include perforated slats or even vision windows.
Types of Coiling Roll-Up Doors and Security Grilles
While there are two basic types of rolling closures — doors and gates (also known as grilles) — there are many options and features that make each style unique.
Rolling Doors
Rolling doors usually refer to garage doors used for warehouses, service garages, parking garages or loading bays. They are usually made from solid metal slats. Perfect for outdoor entrances, they can provide weather protection as well as security. They can also be upgraded with insulation, extra protection or custom designs.
Cornell's rolling service doors come standard with 50,000 open and close cycles. Other models can withstand up to 1 million open and close cycles.
Security Grilles
As opposed to rolling doors typically found outdoors, security grilles are often found inside or under cover. Grilles can come in many configurations, all possessing the critical features of visibility and ventilation. They're a great option for closing off part of a store, restaurant, parking garage or hallway while staying open. They're commonly used in shopping malls, pharmacies and bars.
The visibility allows pedestrians, guards or security cameras to monitor the area while it is closed off. This style also enables better airflow from the closed room or space. This feature can be useful if the location doesn't have a vent or set of independent temperature controls. The room will stay comfortable, so it will be ready for business after reopening each day.
Certain types of coiling security grilles can be etched with a logo, and you can even add aesthetic appeal with elegant woven mesh. Steel and aluminum resist rust and dents, so your grille will always look attractive to patrons.
Max Protection Doors
There are two primary threats to commercial properties — storms and unauthorized entry. Cornell's Max Protection rolling doors have increased strength and security to stop these dangers in their tracks. These doors can create a safe room to protect against a hurricane or tornado, withstanding winds up to 200 mph. Models designed for government buildings and high-security businesses can withstand organized crime attacks and other mob-style assaults for up to 60 minutes.
High-Performance Doors and Grilles
High-performance rolling doors offer the twin benefits of speed and durability. They are incredibly long-lasting, with the MicroCoil Grille offering up to 500,000 low-maintenance cycles. Some models of doors can exceed 1 million cycles while maintaining a low lifetime cost.
High-performance overhead coiling doors open three times faster than standard doors. When opening and closing frequently to maintain security or ensure temperature control, those extra seconds are priceless. These models are excellent for busy loading docks and other commercial applications where shaving off precious time is key to staying competitive.
Fire-Rated Doors
When fire safety is of utmost importance, consider fire-rated commercial coiling doors. These doors meet rigorous fire safety codes and can even react to a fire alarm to stop smoke and flames from spreading. They're crucial to prevent blazes from spreading, and certain types of fire closures can block smoke and gases from traveling up elevator shafts, which may eliminate the elevator lobby requirement in a multi-story building.
Fire-rated doors can meet fire codes with ratings up to four hours. They're suitable for facilities with a high risk of fire, such as commercial kitchens. Any building housing flammable chemicals or situated next to a building that does so can benefit. These doors can also provide a safeguard against equipment malfunctions.
Insulated Doors
Insulated coiling garage doors offer protection from extreme temperatures. Foam-insulated doors improve climate control, keeping spaces warm in the winter and cool in the summer. They also result in lower energy consumption, since the HVAC system doesn't have to work as hard. Another benefit is their ability to muffle noise. This trait makes them perfect for blocking sounds from nearby traffic or noisy operations from next-door businesses.
Counter Shutters
Counter shutters work the same as overhead coiling garage doors. Instead of covering a doorway, they fit a countertop or window frame. They're excellent for ticket booths, concession stands, food courts, service windows and cashier counters. They work for both indoor and outdoor use by securing cash registers and other assets. For foodservice operations, counter shutters can also have fire ratings to protect against grease fires and stop smoke from spreading.
