Ideal for a vast array of applications, from innovative commercial and DIY projects, these polycarbonate lexan sheets are not only impact-resistant but also lightweight, making installation a breeze. Our tinted gray polycarbonate sheets are engineered for longevity and performance to stand the test of time.
Polycarbonate can be used to make windows, storage shelves, machine guards, merchandise displays and other demanding applications. Polycarbonate can be formed and machined, including drilling holes, sawing and routing.
We carry several pre-cut sizes of transparent gray polycarbonate in both 1/8" thick and 1/4" thick sheets. We also offer custom cut-to-size and CNC routing services for those more demanding and technical projects.
Applications: windows, signage, partitions, machine guards, merchandise displays, storage shelves, automotive, aviation, security barriers, marine accessories, skylights, protective shields, face shields, robotic parts, boat windows, patio covers, hobbyist applications, and a variety of other applications.
Key Characteristics of Transparent Gray Polycarbonate:
The Term lexan is commonly used to describe polycarbonate. Actual name brand will depend on current stock.
