Steel windows are characterised by their high load-bearing capacity and are ideal for large surfaces of glazing or buildings under monument protection. Thanks to narrow, thermally broken profiles, they allow maximum light transmission and an elegant, industrial-minimalist look. The material is extremely durable, especially with powder-coated surfaces to protect against corrosion. Environmentally conscious users appreciate the recyclability and timeless aesthetics, which integrate perfectly into lofts or historical architecture.
