Aluminium cladding fixing

Types of aluminium cladding fixing

There are different types of aluminium cladding fixings depending on the application and design requirements. Here are some common types:

• Rivets

  Rivets are permanent fasteners that consist of a mandrel and shank. They provide strong and durable connections. The aluminium sheet is pulled over the mandrel and shank creating a secure joint. The pull rivet connection is suitable for applications with different material thicknesses. It can connect aluminium to other materials. They are installed using a pop rivet gun. The benefits of rivets are high shear and tensile strength. They have a smooth surface and they provide resistance to vibration and movement. The limitations are they require special tools for installation. They have limited accessibility and they have permanent connections.

• Bolts and Nuts

  These are removable and adjustable connections. They consist of a bolt, nut and washer. The aluminium sheets are connected using a bolt and nut with a washer. They provide high strength and load bearing capacity. The advantages of nuts and bolts are easy assembly and disassembly. They have adjustable clamping force and high strength connections. The disadvantages are they require space for the nut and they have a higher weight.

• Self-Tapping Screws

  Self-tapping screws aluminium cladding do not require pre-drilled holes. They create their own threads in the aluminium or metal when installed. This makes installation quick and easy. They are suitable for applications with low to medium load bearing capacity. They have high pull-out resistance and are easy to install. The disadvantages are they have lower shear strength. They create a more visible connection and they require a precise installation angle.

• Adhesives

  Structural adhesives are used to bond aluminium cladding panels to the substructure. They distribute loads evenly across the surface. This reduces stress concentration points. The advantages of using adhesives are they provide a seamless appearance. They have reduced thermal bridging and noise. They also have simple and quick installation. The disadvantages are they have limited load capacity. They require curing time and environmental conditions. Also, their performance depends on surface preparation.

• Cladding Hooks

  Cladding hooks are metal fabrications that support the hanging system of the cladding. They are welded to the steel frame. The cladding panels are slid over the hooks for support. The advantages of cladding hooks are they provide easy installation of panels. They have adjustable positioning and alignment. The disadvantages are they have limited application. They require more labour during installation and they have visible connections.

Functions and Features of Aluminium Cladding Fixing

Aluminum cladding for buildings has multiple applications in the construction industry. It is used for:

• Building Facades: Aluminum cladding is commonly used on building facades. It acts as a protective skin for the building. This ensures the building is protected from severe weather conditions. These include heavy rains, strong winds, and extreme temperatures. Cladding also enhances the visual appeal of a building. It offers a sleek, modern, and attractive finish to the building.
• Exterior Walls: Aluminum cladding is also used on exterior walls. It provides a durable and low-maintenance surface. This protects the underlying structure from moisture, debris, and UV rays. Aluminum cladding exterior walls improve energy efficiency. This is because some cladding panels have insulation material within them.
• Concealed Fixing: Some aluminum cladding panels have a concealed fixing system. This means the screws or fasteners used to attach the panels are hidden from view. This creates a smooth and clean look on the wall. Aesthetically, a concealed fixing system offers a better view than visible fixing panels.
• Exposed Fixing: Other aluminum cladding panels use exposed fixing systems. In this case, the screws or fasteners are visible. This provides easy access for repairs and replacements. It makes aluminum cladding panels easier and quicker to install.
• Interlocking System: Some aluminum cladding panels have an interlocking system. The panels slide and lock into each other to form a continuous surface. This makes the cladding panels very secure. They are resistant to wind, rain, and other elements.
• Rainscreen System: Other aluminum cladding panels have a rainscreen system. This creates a gap between the cladding and the building wall. The gap allows air to circulate and water to drain. This prevents moisture buildup and protects the wall from rot.

Applications of Aluminium Cladding Fixing

Aluminium cladding fixings serve different industries and applications. Here are some common usage scenarios:

• Construction and Building

  Exterior Cladding: Aluminium cladding is used to cover the outside walls of buildings, protecting them from weather damage and improving their appearance. It acts as a skin for the structure. Interior Panels: Inside buildings, aluminium panels are applied to walls. They not only make the space look nicer but are also easy to clean and maintain.

• Automotive

  Car Bodies: When making cars, especially modern ones, aluminium sheets are often used for the outer body panels like doors and hoods. These panels made of aluminum are lightweight and help cars move better.

• Aerospace

  Aircraft Skin: In airplanes, aluminium is used for covering large flat surfaces like wings and fuselage. It is lightweight and strong, which is important for flying. Aluminium is also used for smaller parts of aircraft, like control surfaces that move up and down.

• Marine

  Boat Hulls: Aluminium cladding is sometimes used for the hulls of boats and ships. It is less likely to rust when exposed to water, making it a good choice for marine vehicles. Deck and Superstructure: Within boats, aluminium can be used for the deck, the part where people walk, and the main structure of the ship.

• Electrical and Electronics

  Heat Sinks: Aluminium cladding is used as heat sinks in electronic devices to spread and cool down heat. It helps keep electronics from overheating and working better. Cases and Enclosures: For electronic parts that need to be housed, aluminium cladding is used to make protective cases and enclosures. These can be made very precise using CNC aluminium cladding techniques.

• HVAC

  Ductwork: Aluminium cladding is used to cover air ducts in heating, ventilation, and air conditioning (HVAC) systems. This helps keep the air temperature stable and improves efficiency.

• Signage

  Commercial Signs: Aluminium cladding is often used for business signs that are visible from the street. These signs are made to last, no matter the weather and can be brightly coloured and lit up for easy reading.

How to choose aluminium cladding fixing

When choosing the right aluminium cladding fixings, consider the following factors:

• Load Capacity and Structural Support

  When installing a cladding system, it is important to ensure that the fixing is capable of supporting the load. This includes the weight of the cladding panels and any additional loads such as wind pressure and seismic activity. Consult the manufacturer's guidelines and engineering specifications to determine the appropriate load capacity for your specific project.

• Panel Thickness and Type

  The choice of aluminium cladding panels will directly influence the selection of fixings. Consider the thickness and type of panels, as different panel materials may require specific fixing solutions. Ensure that the selected fixings are compatible with the chosen cladding panels to guarantee optimal performance and longevity.

• Corrosion Resistance

  The location and environmental conditions where the aluminium cladding will be installed will influence the selection of fixings. Areas with high humidity, coastal proximity, or exposure to harsh chemicals may require cladding fixings with enhanced corrosion resistance properties. Consider the environmental conditions to ensure the durability of the fixings.

• Installation Method

  The installation method can affect the performance and longevity of the cladding and its fixings. Some cladding systems, such as curtain walls or rain screens, may require specific fixing techniques, such as through-fixing or secret-fixing methods. Consult the cladding manufacturer's recommendations to determine the most suitable fixing and installation method.

• Adjustability and Alignment

  When installing aluminium cladding, it is important to ensure proper alignment and adjustability. Some fixing solutions offer adjustable features that allow fine-tuning during the installation process to achieve optimal alignment and aesthetic finish. Consider these adjustable fixings to simplify the installation process and achieve a professional result.

• Thermal Bridging

  Thermal bridging is the process of transferring heat through the cladding system. It affects the energy efficiency of the building. To minimize thermal bridging, consider using thermal break fixings or non-conductive materials. These solutions can help improve the building's energy efficiency and reduce heat loss or gain.
