How strong can the Glacier Snow Guards be if they are only made out of plastic?
Glacier brand Snow Guards are made out of a Polycarbonate resin. Polycarbonate is a tough, dimensionally stable, transparent thermoplastic that has many applications that demand high performance properties. This versatile thermoplastic maintains its properties over a wide range of temperatures, from -40″F to 280″F. It is the highest impact of any thermoplastic, transparent up to 2″ in special grades, outstanding dimensional and thermal stability, exceptional machinability, stain resistant and non-toxic.

When exposed to repeated heavy blows, the material tends to cold form rather than shatter.
