The U-470 system is a new board type developed based on the American system and in combination with the actual situation in China. Some of the supporting components in the system have been improved, integrating the advantages of various systems and making it more perfect.
Advantages of plate type
It is quick and convenient to install and simple to construct. Through a dedicated sliding support, the plate and the support fastener are interlocked 360 degrees
It has an attractive appearance and is suitable for the vast majority of building engineering roofs
Due to the special treatment of the plate shape, it has high strength, strong resistance to wind and snow loads, and an effective utilization rate of 78.3%
Through the height of the free edge, it completely blocks out rainwater
