What is the modular product concept? The overall product concept is based on: a well-designed product that solves the known problems of conventional metal roofing tiles, short metal roofing sheets for easy handling, delivery of the product on a Euro pallet so that loading can be achieved even with a passenger car with a cargo area, product packaging in the form of Styrofoam dividers that divide batches into layers of approximately 120 kg, and sheets with consistent shades so that if missing sheets are purchased, the same shade can be achieved on the roof.
