System Detail

Construction & Installation

25 × 80 profiles with dedicated profile carriers

Enlarge drawing & English key

Reading the Drawing

Dedicated hangers engage the top slot of the 25 × 80 profiles and connect them to matching profile carriers.

Numbered Component Key

Match each number to the label below. Dimensions shown on the drawing are in millimeters unless noted.

  1. M8 galvanized hanger rod
  2. 38/50 main-carrier hanger
  3. Profile carrier
  4. Aluminum profile
  5. Dedicated profile hanger
  6. 25 × 80 aluminum profile
  7. Galvanized hanger rod

Installation Steps

  1. Measure the finished elevation required by the ceiling design.
  2. Establish the installation direction. Drill suspension points in the structural ceiling at no more than 1,200 mm spacing and secure the galvanized hanger rods with expansion anchors.
  3. Install and level the profile carriers, keeping the elevation consistent and the carriers no more than 1,200 mm apart.
  4. Insert the dedicated profile hanger into the top slot of the aluminum profile. Secure the member to the carrier and adjust the spacing.
  5. Keep hands clean during installation. Avoid sweat, oil and other contamination on the finished surface.

Surface Finish

Polyester, powder, transfer and roll-coated finishes are finish options for these profiles.
