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.
