Supporting framework: Typically made of aluminum alloy profiles (columns, beams) or steel profiles (for larger spans), it is connected to the main structure through connecting components.
Connection system:
Edge fixation: Usually, aluminum corner blocks (ears) and bolts (sunk head or flat head) are used to connect the folded edge of the board to the frame.
Panel seam treatment: Use sealant (weather-resistant silicone sealant) for waterproof sealing, and it may be accompanied by the use of foam backing strips.
Insulation system: Fill the cavity of the framework with insulation materials (such as rock wool, glass wool), and install a waterproof breathable membrane and a backsheet (such as galvanized steel plate, aluminum plate) on the inner side.
Auxiliary materials: Include gaskets, insulating gaskets (to prevent electrochemical corrosion), etc.
