Polycarbonate

Polycarbonate is available as sheets, rods and tubes. It is usually clear, but an opal sheet for lighting is also stocked. It is used as an impact resistant glazing material.

We have a range of Lexan brand and commercial polycarbonates available. Sheets are stocked in standard or U.V. protected grade.
PolyCarbonate

Options

SHEET: Clear
Size: 2440 mm x 1220 mm Thickness: 1.0 mm to 12.5 mm

ROD: Clear
Diameters: Up to 100 mm diameter.

TUBE: Clear

Polycarbonate is extremely strong and often used as machine guards, protective covers and security glazing. Can be cold bent for ease of fabrication.
We have been involved in making protective parts for many years and will quote to fabricate machine guards. These guards are supplied ready to install on the machine.

Machine guards, security glazing, meter covers, fork lift side screens, light covers, sight glass tubes, electrical guards covers, anti vandal glazing, terminal blocks.
