Our panels are made from solid 5052-H32 tempered aluminum – no vinyl, plastic or foam. The aluminum thickness is a robust 14 gauge, which is 1/16″ thick and quite dent resistant. We’re often asked how the aluminum panels handle hail. Your Peragon bed cover will not be damaged by hail that will damage the sheet metal on your truck. Hail large enough to dent your Peragon bed cover will cause heavy damage to the rest of your truck – making your bed cover the least of your concerns at that point!
