The INCA SOLAR mounting rails for standing seam roof systems continue to be an aesthetic, ergonomic, and cost-effective roof installation system. The INCA SOLAR standing seam device is produced according to the structure of the roof and allows for installation using the compression method instead of drilling the roof. The INCA SOLAR cleat device, with its nut and bolt adjustable head, makes it easy and problem-free to install and eliminates any sliding caused by installation in profile mounting systems. The use of holders and the INCA SOLAR easy nut during the installation phase reduces the installation time and saves time. Our rails are designed to carry panel load as well as wind and snow load according to their capacity and have undergone static tests.
