The fully automated manufacturing process allows for precise cutting of the metal sheets enabling our delivery of the most particular and custom orders. This precise process results in a significant reduction of waste. Green Metal Roofing Inc. offers its customers a choice of seven different colours. Our roof panels are made of German steel sheets with D-Matt coating. The light weight of these tiles, approximately 4.5kg per 1sq.m of metal sheets, is their particular advantage. Due to its lightweight, a metal roof will not affect the existing structure of a building.
