The 3mm polycarbonate sheet is a versatile and durable solution for projects that require lightweight, impact-resistant, and transparent materials. In construction, signage, and protective applications, it offers a reliable mid-range thickness that balances flexibility, durability, and light transmission. Thicker than the 2mm option, it provides enhanced strength while remaining easy to handle, cut, and install. Whether used in safety glazing, industrial panels, or architectural designs, 3mm polycarbonate sheets combine lightweight handling with long-term resistance to impact, UV rays, and weather conditions.
Ideal for signage, protective glazing, roofing, indoor partitions, and DIY projects, these sheets deliver clarity, UV protection, and thermal insulation to meet both commercial and industrial needs. At G-Crystal Plastic Industries, we manufacture and export high-quality, 100% virgin 3mm polycarbonate sheets in bulk quantities to over 60 countries worldwide, providing tailored solutions for distributors, builders, and importers.
What is a 3mm Polycarbonate Sheet?
A 3mm polycarbonate sheet is a mid-thickness, high-performance thermoplastic panel that combines transparency, lightweight properties, and strong impact resistance. Thicker than the 2mm variant, it provides enhanced durability while remaining flexible and easy to handle. This makes it suitable for a variety of applications, including protective glazing, signage, roofing, indoor partitions, and DIY projects. Its ability to transmit light while resisting UV rays and weather conditions makes it a reliable choice for both commercial and industrial purposes.
Key Features of 3mm Polycarbonate Sheets
- Lightweight yet durable: Easy to handle, transport, and install.
- High impact resistance: Significantly stronger than acrylic and far more durable than glass.
- Excellent clarity: Maintains high light transmission for optimal visibility.
- UV and weather protection: Prevents yellowing and degradation in outdoor environments.
- Thermal insulation: Helps maintain energy efficiency in indoor applications.
- Versatility: Suitable for signage, protective covers, roofing, partitions, and creative projects.
What is the weight of a 3mm polycarbonate sheet?
The weight of a 3mm solid polycarbonate sheet is approximately 3.6 kg per square meter.
Polycarbonate weighs about 1.2 kg per square meter per millimeter of thickness, so:
3mm × 1.2 kg = 3.6 kg/m²
The exact weight may vary slightly depending on manufacturer tolerances and UV coating layers.
What is the price per square meter of 3mm polycarbonate sheet?
The price of a 3mm polycarbonate sheet per square meter depends on raw material costs and order quantity.
If the average price ranges from $2 to $3 per kg, and the sheet weighs about 3.6 kg/m², the estimated price per square meter would be:
Approximately $7.2 to $10.8 per m²
Final pricing depends on:
- Order volume
- UV coating options
- Shipping destination
- Packaging requirements

Frequently Asked Questions
Is 3mm polycarbonate sheet thick enough for outdoor roofing?
Yes, 3mm polycarbonate sheets can be used for outdoor roofing in areas with low to moderate wind loads when properly supported with strong framing.
For high-wind zones, industrial roofing, or large-span structures, 4mm or 6mm sheets are recommended for added strength and durability.
Can 3mm polycarbonate sheets be curved?
Yes. 3mm polycarbonate is highly flexible and can be cold-bent without cracking.
It is suitable for curved applications such as domes, arches, skylights, canopies, and wave-style roofing designs.
Do you offer 3mm twin-wall polycarbonate sheets?
Twin-wall polycarbonate sheets typically start at 4mm thickness and above.
If insulation or thermal performance is required, 4mm or 6mm twin-wall sheets are the better option.
Can I print, CNC cut, or laser-cut 3mm polycarbonate?
Yes. 3mm polycarbonate sheets are suitable for CNC routing, laser cutting, drilling, and screen printing when using appropriate tools and temperature control.
This makes them ideal for signage, displays, and custom fabrication projects.
