What is the concept of a modular product? The overall concept of the product is based on: a properly constructed product that solves the known problems of conventional metal roofing tiles, short metal roofing sheets so that they can be easily moved, delivery of the product on a Euro pallet so that loading can be carried out even by a passenger car with a cargo area, packaging of the product in the form of polystyrene dividers that divide the batches into layers of approximately 120 kg, sheets with repeatable shades so that after purchasing the missing sheets, the same shade can be obtained on the roof.
