I Structures for typical systems



II Characteristics of the system
1. With a long history and wide application, this maintenance system has a mature force-transferring structure, suitable for roofs or walls with ≥1.5°grade.
2. The system can be executed on spot as its construction is very easy, with a wide span (≤200m) of single panels usually without joints or screw holes. And, the lock seam is very stable.
3. Excellent drainage and anti-seepage performance with unique anti-heat-expansion performance as well as safe anti-wind-pressure performance.
4. With an advanced secondary molding technique (melon-peel technique and sector curve technique), this system can easily settle problems of single or double curved surface overlay.
5. High quality, low power-consumption, practical, good looking and environ
