With over 18 years in the global plastic industry, Unisign focuses on high-grade polycarbonate sheet (PC sheet) production using 100% virgin raw materials and modern extrusion lines. Our sheets are optimized for high UV index environments and shipped worldwide for major commercial roofing, greenhouses, and safety glazing projects throughout South Africa.

How long does a polycarbonate sheet last?
The lifespan of a polycarbonate sheet in high-UV environments like South Africa depends on the quality of its UV protection layer. Standard sheets may yellow and become brittle within a few years; however, Unisign PC sheets feature premium co-extruded UV protection that allows them to last 20 years or more. This is essential to maintain structural integrity and clarity against the intense African sun and rapid temperature shifts.
By choosing Unisign as your polycarbonate sheet supplier, you ensure your projects resist the degradation caused by the high Highveld radiation levels. Our products reduce long-term maintenance costs and replacement frequency, making them the preferred choice for South African roofing contractors and industrial developers.
Is polycarbonate good for roofing?
Yes, Polycarbonate Sheets are the ideal choice for South African roofing because of their legendary impact resistance (hailed as “shatterproof”) and superior thermal properties. They offer high light transmission (up to 90% for clear sheets), while providing better insulation than traditional IBR or corrugated metal, making them perfect for carports, patios, and commercial greenhouses.
Unisign polycarbonate sheets are engineered for long-term outdoor exposure with UV layers on both sides. Our panels come in thicknesses from 4mm to 20mm, with tinted colors like Bronze and Opal being top sellers in South Africa to help manage heat gain. Sourcing from Unisign means getting factory-direct wholesale pricing, consistent quality from virgin resins (Covestro/Sabic grade), and profiles designed to withstand severe hail impact.


How strong is polycarbonate?
Polycarbonate (PC sheet) is renowned for its exceptional high-impact strength, making it one of the toughest plastics on the market. It is approximately 250 times stronger than glass and 30 times stronger than acrylic, while remaining lightweight and flexible. This makes it the essential material for South African safety glazing, riot shields, machine guards, and especially roofing in areas prone to large hail.
Unisign Polycarbonate Sheet South Africa supply uses premium virgin resin from Covestro and Sabic to deliver consistent impact performance that meets international standards. Our sheets maintain their flexibility and strength from -40°C to +120°C, ensuring they don’t crack during sudden Gauteng storm shifts. Choose Unisign for high-performance applications where maximum durability is non-negotiable.
Which is better, PVC or polycarbonate?
Both PVC and polycarbonate are common in the market, but Polycarbonate (PC sheet) is clearly superior for applications requiring long-term durability and impact resistance. While PVC is cheaper, it is far more likely to become brittle and crack under South Africa’s high UV levels and hail. Polycarbonate offers up to 90% light transmission, is virtually unbreakable, and retains its properties for decades.
Unisign polycarbonate sheets outperform standard PVC with better UV stability and superior thermal insulation. Unlike PVC, our PC sheets offer a shatterproof guarantee, making them safer for schools, public areas, and industrial facilities. Choose Unisign for high-performance projects like skylights and walkways where quality and reliability matter most.


Which color polycarbonate sheet is best?
The best color depends on your specific light vs. heat requirements. For the intense South African sun, tinted sheets are highly recommended to reduce energy costs. Here is a guide:
| Color | Light Transmission | Heat Reduction | Best For South African Projects |
|---|---|---|---|
| Clear | 93% | 0% | Greenhouses, safety screens, internal glazing. |
| Opal | 49% | 52% | Workshops, offices, privacy screens. Great for soft, diffused light. |
| Bronze | 38% | 33% | Patios, pergolas, carports. Very popular in residential SA roofing. |
| Grey | 19% | 58% | Maximum heat block for industrial warehouses and sunny facades. |
Unisign offers all these wholesale polycarbonate colors using premium UV-protected resin, ensuring long-term color stability. Our Bronze and Grey sheets are specifically popular in South Africa for their superior glare and heat reduction. Available in standard thicknesses 4mm-20mm with custom bulk order support.
