Features
1. FM cerfification
2. Reduce the error produced by traditional hard tube configuration of stress effectively, and then reduce the crack occurs.
3. Allow the main hard tube and the relative displacement between the ceiling skeleton, and at the time of the earthquake, which can effectively reduce the skeleton line or crack caused by the excessive stress, will affect air tight.
4.Non-pollution:Stainless steel construction requires without painting or epoxy coating on side.
5.Simple Installation: 10 times faster than using conventional system, save time, save costs, faster clean room certification and running.
6.Good Flexibility: Eliminate potential leaks and protect gel seals during seismic activity, Allow the independent way between ceiling grids
and main water pipe. Eliminate ceilings stress and leak due to misaligned hard-piped installation.
7. Easy Relocation:No downtime while sprinklers head are being moved to accommodate tool or floor-plane configuration.
8.Safety: stainless steel to sure in case the fire break out the sprinkler system works without blockage.
