PC Hollow U-Locked Sheet

U-lock polycarbonate sheets are the latest development. This system uses a free sliding support and is a fundamental solution to the problem of thermal expansion and contraction of regular polycarbonate sheets at various operating temperatures. The vertical cap edge design prevents water leakage during installation throughout the system. The innovative aspects of the U-lock design make installation easier and faster, increase strength and facilitate maintenance.
