The Types of Building Entrance Rolling Doors

Standard

• The basic roll-up door is the standard door. A standard door is is made of 22-gauge steel slats. The standard height is 8 feet tall and 20 feet across. This door is ideal for a commercial establishment that needs a medium size opening for large equipment or to receive shipments and does not require very high security measures. The barrel can be in either four- or six-inch diameters. You can operate it with either a left or right hand crank or use a tube motor to power the door.

Insulated

• For businesses that require specific temperature requirements, an insulated roll-up door is one option. This door uses polyurethane insulation to give the door an R-value of 7.7. The door slats are made of 24-gauge steel and operate a chain mechanism. The barrel springs are rated for 20,000 life cycles. Vinyl weather stripping on the bottom of the door prevents air leakage.

Security Grille

• The security grille door is found in shops in the mall. This style door uses thin aluminum that runs the width of the door to provide a lightweight and secure barrier. The plank pattern can come in either brick or straight. One advantage of this door is that since you can look through it, customers can view your merchandise from the store entrance, even though your store is closed. This door operates with a hand crank. It may mount to an interior or exterior wall and have a maximum available width of 30 feet.

High-Grade

• If your business requires high security measures or a very large opening, a high-grade roll-up door is the best. This door uses 18 -gauge steel for added strength. The slats are flat, flat with insulation or a contoured slat with an angle. Doors come up to 40 feet across. The operation methods to raise and lower the door include hand chain, hand crank or a wall-mounted motor.
