Yixing Zhonghuan DW Phase IV Project is an important project in Yixing Economic and Technological Development Zone, and the steel structure metal roofing area of this project is about 60,000 square meters. The waterproof layer is made of 1.5mm thickness fabric inner reinforced thermoplastic polyolefin (TPO) waterproof membrane, and the construction method is fixed by non-perforated mechanical construction method.
The advantages of BNBM OTAi non-perforation mechanical fixation system：
- Compared with the mechanical fixing method with perforation, the construction efficiency of mechanical fixing without perforation is higher.
- It is not necessary to fix the edges of each roll.
- No need to consider the width of membrane.
- No need to cut the membrane (reduced membrane lap seams).
- The wind load can be distributed more evenly.
- Improve the level of wind resistance, currently the highest level can reach FM 1-210.
- The roof is more beautiful to look at.
- Improve construction efficiency and reduce labor intensity of workers.
