Solid Polycarbonate Sheet Specifications at a Glance
If you are specifying solid polycarbonate (PC) sheet in 2026, these are the numbers that matter. Thicknesses run from 1 mm to 30 mm, standard widths are 1220 / 1560 / 1820 / 2100 mm, and standard sheets are 6 m long with custom rolls up to 30 m. Clear sheet transmits up to 89% of visible light and delivers roughly 250 times the impact strength of glass at about half the weight.
The bottom line: solid PC sheet is the go-to glazing material wherever impact resistance, clarity and light weight all matter at once — machine guards, safety glazing, sound barriers, signage and skylights.

Thickness and Weight Reference Table
Solid PC sheet weighs about 1.2 kg per square metre for every millimetre of thickness (density 1.2 g/cm³). The table below converts thickness to weight and suggests typical uses.
| Thickness (mm) | Weight (kg/m²) | Typical Use |
|---|---|---|
| 1 | 1.2 | Lamination, overlays, thin glazing |
| 1.5 | 1.8 | Light diffusers, protective covers |
| 2 | 2.4 | Light boxes, thin glazing |
| 3 | 3.6 | Machine guards, signage |
| 4 | 4.8 | Glazing, machine guards, shelters |
| 5 | 6.0 | Security glazing |
| 6 | 7.2 | Safety glazing, sound barriers |
| 8 | 9.6 | Skylights, partitions |
| 10 | 12.0 | Heavy-duty safety glazing |
| 12 | 14.4 | Security glazing, barriers |
| 15 | 18.0 | Security and impact panels |
| 20 | 24.0 | Structural panels |
| 25 | 30.0 | Custom structural panels |
| 30 | 36.0 | Custom structural / ballistic panels |
Standard Sizes: Width and Length
Our factory runs four standard widths — 1220 mm, 1560 mm, 1820 mm and 2100 mm — which lets you cut to job size with minimal waste. Standard sheet length is 6 m, custom lengths from 1 m to 12 m are available, and thin sheets (up to a few millimetres) can be supplied in rolls up to 30 m.
Solid PC sheet is easy to fabricate on site. It cuts, drills and routs cleanly, and can be cold-bent to a radius of about 150 times the sheet thickness. For fixed glazing, sheets are normally secured with aluminium profiles and self-tapping screws, with over-size pilot holes to allow thermal movement.
Optical, Mechanical and Thermal Performance
Clear solid polycarbonate transmits up to 89% of visible light — essentially on par with glass. Tinted sheets transmit less: bronze and grey typically 35–48%, opal/diffused white 55–68%. The co-extruded UV protection layer stops the material from yellowing, which is why solid PC glazing carries a 10–15 year outdoor warranty.
Mechanically, solid PC delivers flexural strength of at least 90 MPa and tensile strength of at least 60 MPa, with impact resistance roughly 250 times that of glass. It stays serviceable from −40 °C to +120 °C, and standard grades meet B1 (GB 8624) and UL94 V-0 to V-2 fire ratings — self-extinguishing and free of flaming droplets.
Common Applications for Solid Polycarbonate Sheet
- Machine guards and safety shields
- Bus shelters and canopy glazing
- Highway and railway sound barriers
- Advertising light boxes and backlit signage
- Skylights and sunrooms
- Swimming pool and balcony enclosures
- Security and anti-vandal glazing
Why Jietai as Your Solid Sheet Manufacturer
Jietai is a polycarbonate sheet manufacturer, not a middleman. We extrude solid PC sheet in-house across the full thickness and width range, apply the UV layer at the die, and cut to custom size before export. That means you get factory-direct pricing, consistent colour and thickness, and a single point of contact for specification support. Contact our team for a quote on your project.
Frequently Asked Questions
What thickness of solid polycarbonate sheet do I need?
It depends on the application. Thin sheets (1–3 mm) suit light boxes, signage and simple guards; 4–6 mm is the workhorse for glazing, machine guards and shelters; 8–12 mm handles heavy-duty safety glazing and skylights; and 15 mm and above is used for security and structural panels. Tell us your span and load and we will recommend the right thickness.
What are the standard sizes of solid polycarbonate sheets?
Standard widths are 1220 mm, 1560 mm, 1820 mm and 2100 mm, with a standard length of 6 m. We also supply custom lengths from 1 m to 12 m, and thin sheets can be supplied in rolls up to 30 m.
How much does a solid polycarbonate sheet weigh?
Solid PC sheet weighs about 1.2 kg per square metre per millimetre of thickness. A 4 mm sheet is about 4.8 kg/m² and a 10 mm sheet about 12 kg/m² — roughly half the weight of glass of the same thickness.
How much light does solid polycarbonate sheet transmit?
Clear solid polycarbonate transmits up to 89% of visible light, close to glass. Tinted colours transmit less: bronze and grey typically 35–48%, and opal/diffused white 55–68%.
Is solid polycarbonate sheet fire resistant?
Yes. Standard sheets meet B1 (GB 8624) and UL94 V-0 to V-2 ratings and are self-extinguishing — they do not support combustion or produce flaming droplets the way some other plastics do.
