 Introduction
Solid P.C. Sheets have very high Impact strength
(over 200 times the impact strength of glass and over 10 times the impact strength of FRP & Acrylic),
making them the ideal choice for place where the safety issue arise.
Our P.C with hard coating protect from breakage and will reduce the cost of building maintenance.
And our P.C is very durable and long lasting by virtue of their high impact strength and UV Protection.
Application
a. Double insulted window of air-conditioned coaches with outer in Bronze and inner in clear glass
b. Outer layer of the main air conditioned railway coaches (Inner : Glass)
c. Single layer glazed window for the engine in front and back
d. Single window for Metro/Tube
