5. Installation:
      (1) Flush type installation

  1. Cut off protective films for 5 to 10mm before inserting sheets to the support frame, because the protective film would cause inefficient adhesive between tamping and PC sheets.

  2. Since the expansion and contraction degree of PC sheets, are different from that of medal frames, as well as PC sheets are flexible and taking air pressure, therefore, appropriate insertion, reserving space for expansion and shrink because of temperature changes, and choosing suitable thickness of PC sheets are necessary. 
    General sheet should be inserted into fixed frame for over 25mm, with at least 2 ribs installed into the fixed  zone. 3mm place will be reserved for expansion or shrinkage. (Expansion ratio: 0.065mm/m)    

      (2) Screw installation

  1.  When installed with screw, all rivet holes should be larger to reserve space for expansion and contraction.  Usually, the holes should be larger than that of the bolt or rivet stems by 50%" so as to avoid expansion or  shrinkage. 

  2.  when drill, and cover the exposed portion with silicone compound to prevent detergents permeating which  brings damage to pc sheets, and avoid gradual cracks.

  3.  Rivet heads should be larger than the stems by 2 times. Use gaskets or washers to avoid the rivet  heads touching pc sheets, and reduce the pressure.

  4.  Do not screw it too tightly.

  5.  Do not use PVC gaskets.

  6.  The bending part should be avoided using screw for cold bending process.
