♦   North Space vertical locked joint roof plate (NS-360)
　　NS-360 is connected with 3600 double vertical locked joints and locked with the

   special stainless clips fixed in the locked slots and roof summers. At present,

   the system is the  best option for its waterproof, maintenance free character

   and lastingness. It completely eliminates the possibility of leakage. Most of

   all, because of the sliding character of stainless clips, it effectively avoid

   the deformation of roof plates caused by the variation of roof temperature.
  

♦   North Space general plate (NS-RW)
　　NS-RW is a type of high-quality and economic roof and wall plate. The base

   adopts high-tension aluminum and zinc coated alloy steel plate and SMP (epoxy)

   coated surface or PVDF (fluorocarbon) coated surface. In addition, the advanced

   measures at the side joint of the steel plate, such as buckling waterproof,

   sealing material, siphon-resistance treatment and the rib of 30mm height all

   enhance the waterproof performance.
