Slats

The slat is the most prominent component of an aluminum roller shutter. It is the sheet of aluminum that rolls up and down to open and close the shutter. The thickness of the slat can be different depending on the level of security required, with thicker slats providing greater protection against forced entry attempts. The slat is also available in a range of colors and finishes to match the aesthetic of the property.

Thickness: Aluminum roller shutter slats can vary in thickness depending on the level of security required. For example, a slat with a thickness of 1.2mm may be suitable for a residential property, while a 2.0mm slat may be more suitable for a commercial property. ULEPANDA provides 39mm*0.22mm, 40mm*0.30mm, 45mm*0.25mm, 55mm*0.30mm, 77mm*0.44mm, 77mm*0.53mm&77mm*0.68mm stats. To learn more about slats.

Colors and finishes: slats are available in a range of colors and finishes to match the aesthetic of the property. Some common colors include white, black, gray, and beige, while some common finishes include smooth, perforated, and wood grain.

Guide rails

Guide rails are the channels that the slat rolls up and down in. They are typically made of steel or aluminum and have nylon or plastic inserts to reduce friction and noise, being attached to the sides of the opening. The guides ensure that the slat remains in place and does not move from side to side when opening and closing. The surface of the guide is finished with a high-quality powder coating.

Material: Guide rails are typically made of steel or aluminum through extrusion. Steel guides are often stronger and more durable, while aluminum guides are lighter and less expensive.

Size: It can be different models and sizes. Guides come in different sizes depending on the size of the shutter. For example, a guide with a width of 60mm may be suitable for a smaller shutter, while a guide with a width of 100mm may be more suitable for a larger shutter.

Bottom Sill

The bottom sill is the component that locks the shutter in place when it is fully closed. It is typically made of aluminum or steel and has a rubber seal to provide insulation and prevent drafts from entering the property. The bottom sill is also available in a range of sizes and finishes to match the aesthetic of the property.

Material: Bottom sills are typically made of aluminum or steel. Aluminum bottom sills are often lighter and less expensive, while steel bottom bars are stronger and more durable.

Size: Bottom sills come in different sizes depending on the size of the shutter. For example, a bottom sill with a height of 40mm may be suitable for a smaller shutter, while a bottom bar with a height of 100mm may be more suitable for a larger shutter.

Motor

Most modern aluminum roller shutters are motorized, which means that they are operated by an electric motor. The motor is typically located inside the axle and is controlled by a remote or a switch. The motor provides a smooth and efficient opening and closing of the shutter, and can also be integrated with a smart home system for remote control and automation.

Type: There are two main types of motors for aluminum roller shutters: AC motors and DC motors. AC motors are often more powerful and better suited for larger shutters, while DC motors are more energy-efficient and better suited for smaller shutters.

Power: The power of the motor is measured in newton meters (Nm) and determines how much weight the motor can lift. For example, a motor with a power of 50 Nm may be suitable for a smaller shutter, while a motor with a power of 120 Nm may be more suitable for a larger shutter.

Control system

The control system is the mechanism that controls the motor and the shutter. It can be operated by a remote control, a switch, or a smartphone app. Some advanced control systems also offer automation features, such as scheduling the opening and closing of the shutter based on the time of day or weather conditions.

Type: There are several types of control systems for aluminum roller shutters, including remote control, switch control, and smartphone control. Some advanced control systems also offer automation features, such as scheduling the opening and closing of the shutter based on the time of day or weather conditions.

Connectivity: Some control systems can be integrated with a smart home system, allowing the shutter to be controlled remotely from a smartphone or other smart device.

Axle

The axle is the component that the slat is wrapped around when the shutter is opened. It is supported by two end caps and one side of the axle is connected to the motor and the other is connected to the shaft. It is typically made of steel or aluminum and is designed to withstand the weight of the slat. The axle is also available in a range of sizes to accommodate different sizes of slats.

Material: The axle is typically made of high-quality aluminum and has various shapes, such as an Octagonal axis, Plum shaft.

Size: The size of the axle depends on the size of the shutter. For example, a shutter with a width of 3 meters may require a barrel with a diameter of 205mm, while a shutter with a width of 5 meters may require a barrel with a diameter of 250mm.

Locking mechanism

The locking mechanism is the component that secures the shutter in place when it is closed. It can be a manual lock or an automatic lock that is activated by the motor. The locking mechanism is one of the most important components of the shutter, as it is the primary means of protecting the property against forced entry attempts.

Type: There are several types of locking mechanisms for aluminum roller shutters, including manual locks and automatic locks. Automatic locks can be activated by the motor and may offer greater security than manual locks.

Security level: Locking mechanisms can vary in their level of security. For example, a locking mechanism with multiple locking points may offer greater security than a locking mechanism with a single locking point.

Spring

The spring is applied to connect the slats with the axle, so that the slats can be opened or closed to realize smooth operation with a tubular motor. It is commonly made from aluminum and the most popular color is white, but the color of spring can be customized to meet your needs.

Material: Springs are generally made of aluminum and steel, which require a high elastic limit. The size of the spring hanger shall be determined by the weight of the slat. The larger the weight of the slat, the higher the requirement of the spring.

Roller shutter box

The roller shutter box is the housing of the roller shutter slat and is mounted on or in front of the window, depending on the model. The sides of the box have different angles such as 45⁰ and 90⁰. It is usually made of aluminum and steel and has different models. When we choose roller shutter box, we have to consider the size of the slat.

Type: Roller shutter box can be roll-formed and extruded. In the market, there are several types of roller shutter boxes. They can be round, quarter-round, 20°and 45°shutter boxes, and built-in boxes. You can choose one kind of box according to your preference and the style of the building.

Bearing

A bearing is used in the roller shutter and works when a security break is not fitted with the system. It is attached to the cheek plate and helps the barrel move normally.

Function: The bearing has three important functions. It is usually used for carrying weight, reducing friction and positioning movement.

Material: Bearings are usually made of hardened steel and are hard and wear-resistant. The type and size of bearing shall be determined according to the actual drive shaft.

Conclusion

Aluminum roller shutters are a popular security solution for commercial and residential properties due to their durability, security, and aesthetic appeal. The various components of the shutter work together to create a reliable and functional security solution. By understanding the different components of an aluminum roller shutter, property owners can make an informed decision about the type of shutter that best meets their security needs.
