Alucobond ACP (Aluminum Composite Panel) can be installed using a hidden rivet method. 

    This involves securing the panels to the substructure using rivets that are concealed within the panel joints, creating a clean, seamless look. 

    This method requires careful planning and execution to ensure proper alignment, secure attachment, and allowance for thermal expansion. 

    Here's a more detailed breakdown of the hidden rivet installation process:

  1. Preparation:

   Panel Cutting and Fabrication:

   The ACP panels are cut to the required size and shape, including any necessary folds or grooves for the hidden joint system. 

   Substructure Preparation:

   The substructure (usually aluminum or steel framing) is installed and leveled, providing a secure base for the panels. 

    Hole Drilling:

    Holes are drilled through the panel and the substructure at designated locations for the rivets. These holes should be centered and of the correct diameter for the chosen rivets. 

   It's crucial to ensure the protective foil is removed only from the area to be riveted before drilling. 

   Rivet Selection:

    Blind rivets with stainless steel mandrels are commonly used for exterior applications to prevent corrosion. 

   2. Installation:

    Panel Positioning:

    The ACP panel is carefully positioned onto the substructure, aligning the pre-drilled holes. 

     Rivet Insertion:

     The rivet is inserted into the aligned holes, and the rivet gun is used to set the rivet, ensuring a secure and flush connection. 

     Joint Finishing:

    Depending on the specific system, sealant or filler might be used to create a waterproof seal within the joint, or a separate piece might be inserted to conceal the joint. 

   3. Considerations:

   Thermal Expansion:

    ACP panels expand and contract with temperature changes. The installation should allow for this movement, either through oversized holes or flexible sealant. 

    Joint Design:

    Various hidden joint designs exist, including rainscreen systems with male/female connections and those utilizing specific folds and clips. 

    Testing:

    It's recommended to test the riveting process on a sample panel to ensure proper rivet selection and technique before starting full-scale installation. 

    Professional Guidance:

    Consult the Alucobond installation guidelines and, if needed, seek professional advice for optimal results, especially for complex projects.
