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 No. 40 secondary carriers, keeping the elevation consistent and the carriers no more than 1,200 mm apart.
  4. Insert M6 hex bolts into the top slot of the 50 × 75 bullet-head 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.

These system details explain the illustrated assembly. Anchor selection, structural capacity and final suspension spacing must follow the approved project drawings and local requirements. Different carrier configurations are not interchangeable.

Typical Applications

Public-building passages, airports, exhibition halls, shopping centers, stations and tunnel corridors.
