  • Roofs above 60°.
    For buildings higher than 30 meters, please consult VMZINC China.
  • Curvature:
    - For horizontal panels: radius > 10 m
    - For vertical panels: radius > 3 m
  • Soffit installation: panel maximum 2 meters long.
 

Support
The support must be:

  • Rigid and continuous.
  • Meet loading requirements in conformity with a minim um pull out strength of 50 daN for each clip.
  • Rest on at least 3 bearing structure elements.
