SEISMIC BRACING SUPPORT SYSTEM

Recent events around the globe have highlighted the need for consideration around the seismic restraining of support systems in construction and industry. The Unistrut seismic catalogue information shows how certain existing support systems can be seismically retrofitted, and gives guidelines around new installations.

PolyblindTM Film & Glass

 
PolyBlindTM (Electronic curtain) is one of our latest technologies; a patented technology that divides switchable sections as a curtain or shutter, one section at a time in a single piece of film or glass without visible wires. It can be programmed to transition up or down, or you can program only one or two sections at a time to be “private” while others are clear.  

PolyBlind™ (Electronic curtain) can be installed in the office, study room, bathroom, show room, VIP room, etc. There are so much advantage that you can think such as cutting down on germs and allergens, decreasing the dust in your place, protecting your privacy, etc.

Uniqueness
  • Design for indoors and outdoors.
  • Replace blinds and curtains with a dust-free easy-clean glass blind.
  • UV protection >99%.
