Polycarbonate Sheet
Polycarbonate is a thermoplastic that comes in a transparent sheet and offers unique durability and is resistant to water and impact damage. Compared to acrylic plastic, polycarbonate has a higher impact strength and is more durable than acrylic, making polycarbonate the preferred form of plastic for many. Not only is polycarbonate incredibly light, but it’s also virtually impossible to break and has excellent resistance to many forms of damage.
No matter what project you’re using polycarbonate for, polycarbonate sheets can be cut-to-size to make sure it’s the perfect fit to match your specifications.
Advantages :
Resistant to water and impact damage.
Tough quality and minimal moisture absorbance.
They also have excellent heat resistance, stability and are flame-retardant and chemical resistant.
Working with polycarbonate sheets is easy and the material can effortlessly cut and fixed with screws, nuts and bolts. Using thermoforming and machining, polycarbonate can be shaped and sized with ease.
When heated at its melting point of 155 degrees celsius, polycarbonate becomes a liquid and can be cooled and reheated continuously without significant degrading, making it easy to recycle or have injection moulded.
It can bear weight both horizontally and vertically.
It can bear weight both horizontally and vertically.

Methods :
A] Four Sides Clamped Flat Glazing
This method utilizes comparatively small, separate glazing elements, cut from large sheets, Multiwall sheet is put inside a four - sided frame or supporting structures and clamped on all sides. Clamping is done by plastic, wood or metal clamping profiles, with or without rubber sealing strips, and fastened by nails, screws or blots to the supporting frame. The frame itself can be made of wood or metal, according to the design
B] Two-side Clamped Arched Glazing
Multiwall sheets can be curved into arches within the petmitted radius with no damaging effect to mechanical performance. Moreover, internal stresses induded by curving give it extra strength and rigidity elements.
C] Mid-sheet Fasteners
Resistant to water and impact damage.
Fastening is usually done by screws, inserted along the supporting internal purlins, spaced about 500mm(20in.) apart.
Along the edge purlin, the fastning screws should be inserted about 300mm (12in.) apart.
A hole must be pre-drilled into each screw location. The diameter of that hole should be 2mm large that of the screw, to allow for thermal expansion movements. In case of dark colored sheets predrill even large holes, and use wider fastener washers.
Use of self-tapping or self drilling screws is recommended. In case of wooden structures, suitable wood - screws should beused. All the screws should be corrosion resistant, with at least heavy-duty hot-dipped galvanized finish, or stainless steel (if used in an extremely corrosive environment). The screw should be 6mm (1/4in.) diameter, with length according to sheet thickness, type of washer and type of supporting structure.
Positioning the Sheets
Multiwall sheets should be installed with the rib channels sloping downwards. That orientation will reduce accumulation of dirt inside the sheet and ease gravity draingage of condensation moisture.
Sheets should be installed with the adjoining edges connected by a glazing profile suited to the glazing system.
For sheets installed in the flat, horizontal position, (roofs, overhead skylights), a minimum slope of 5 % is imperative, with 10 % and above preferable. Steeper slopes offer better rainwater drainage and selfcleaning, and lessen the risk of water and dirt infiltration through the connectors and fastening screws. They also help to diminish the visual effect of sheet deflection caused by loading.
Arching Radius
Multiwall sheets may be cold bent, or curved up to their permitted radius, using polycarbonate’s natural properties, without need of a thermal process, curving sheet beyond this permitted radius induces undue stresses and straining the glazing sheet, causing premature failure.
