Hot-Rolled Steel
For over a century, hot-rolled steel has been a leading material in door and window construction, renowned for its unique textures that showcase the raw beauty of the steel. The hot-rolling process creates distinctive “beauty marks,” adding character and making it an ideal choice for slim, elegant profiles.
Windows and doors crafted from hot-rolled steel feature seamless welded corners, ensuring exceptional durability. Depending on the desired aesthetic, welds can be left natural, smoothed flat, or treated for a polished silver shine or elegant black patina.
With a blend of classic hot-rolling techniques and modern technology, hot-rolled steel is a sophisticated choice for any architectural project, combining tradition with contemporary design.

Stainless Steel
Since 1920, stainless steel has been a premier choice in construction and architecture, valued for its exceptional durability and resistance to harsh environments. Its longevity makes it ideal for roofs, curtain walls, doors, and windows that require minimal maintenance.
The metallic shine of stainless steel offers extensive design flexibility, including distinctive finishes like “black stainless steel,” achieved through special patinas. This unique texture adds elegance to both windows and doors.
Stainless steel products often feature elegantly welded corners with polished finishes. The premium AISI 316L alloy, known for its outstanding corrosion resistance, even in marine environments, ensures both durability and aesthetic appeal.

Cor-Ten Steel
Cor-Ten steel is celebrated for its dramatic aesthetic and extraordinary elegance, making it a popular choice for windows and doors in both restoration projects and new constructions. This natural, living material evolves over time, developing unique shades through exposure to the elements.
The natural oxidation process can be chemically controlled to reduce “bleeding.” However, to manage these effects, it is advisable to schedule periodic treatments with suitable waxes or oils. The corners of the frames are expertly welded, with options to leave the welding marks natural or ground flat.
Cor-Ten steel enhances architectural designs, providing a striking element that integrates beautifully into a variety of styles.

Architectural Bronze
Architectural bronze is a prestigious metal favoured by architects for its unique aesthetic qualities. This living material naturally oxidises, revealing a beautiful palette of warm tones, from golden yellows and copper reds to deep browns with hints of copper green.
The oxidation process can be enhanced through patination to create a harmonious effect, or a protective finish can be applied to preserve the original golden shine. The corners of windows and doors made from architectural bronze are meticulously welded and ground flat for a seamless look.
Ottostumm | Mogs Architectural Bronze is a specially designed copper alloy extruded with high precision. With a smooth surface ideal for bending, and available in satin or polished finishes, it embodies the evolution of this ancient material for contemporary architecture.

Brass
Brass, made from the cold-working of the OT67 copper alloy, is renowned for its striking colour and shine, combined with hardness and corrosion resistance. This makes it an exceptional choice for architectural applications in both traditional and modern designs.
Surfaces in glossy or burnished brass can convey luxury and refinement, or evoke a sense of tradition. When exposed to air, this alloy develops a richness resembling antique bronze while retaining its physical properties. The natural oxidation provides a level of self-protection, making it suitable for challenging environments, including maritime settings.
Secco Sistemi utilises the OT67 alloy, which contains 67% copper for superior corrosion resistance and 33% zinc to enhance hardness and load-bearing capabilities. This makes brass a highly sustainable option, boasting 100% reusability.
