Examples:

1. Installation of Aluminium Sliding Door:

   • Frames and Shutters: Select aluminium profiles for the frame and shutters, ensuring they meet the specified dimensions and thickness.
   • Glazing: Use clear laminated glass for the sliding door panels.
   • Hardware: Install handles, locks, and sliding tracks.
   • Fixing: Secure the aluminium frame to the masonry opening, ensuring it is plumb and level. Insert the glass panels into the frame and secure with rubber gaskets.
   • Testing: Ensure smooth operation of the sliding mechanism and proper locking.

2. Construction of Aluminium Curtain Wall:

   • Frames and Panels: Choose aluminium profiles for the frame and panels that meet the required specifications for dimensions and thickness.
   • Glazing: Use double-glazed units with low-emissivity (Low-E) glass for thermal insulation.
   • Hardware: Install brackets, anchors, and gaskets to secure the curtain wall system.
   • Installation: Assemble the frame and fix it to the building structure, ensuring proper alignment. Install the glass panels and apply sealants to ensure weatherproofing.
   • Inspection: Check for proper alignment, sealing, and thermal performance.

3. Erection of Aluminium Partition:

   • Frames and Panels: Select aluminium profiles for the partition frame and panels, ensuring they meet the specified dimensions and thickness.
   • Glazing: Use frosted glass panels for privacy.
   • Hardware: Install hinges, locks, and handles as required.
   • Fixing: Secure the aluminium frame to the floor, ceiling, and walls, ensuring it is plumb and level. Insert the glass panels and secure with rubber gaskets.
   • Testing: Ensure stability and proper operation of doors or movable panels within the partition.

4. Installation of Aluminium Cladding:

   • Panels and Fixings: Choose aluminium composite panels (ACP) for cladding, ensuring they meet the required specifications for dimensions and thickness.
   • Hardware: Install brackets, anchors, and sealants to secure the cladding system.
   • Installation: Fix the aluminium panels to the building structure, ensuring proper alignment and spacing. Apply sealants to ensure weatherproofing and thermal insulation.
   • Inspection: Check for proper alignment, sealing, and overall appearance.
