Performance you can feel

The aesthetics of steel, the lightness of aluminum, the comfort of a modern home

The ALU STEEL series is the perfect solution for those who love industrial aesthetics — slim lines, defined profiles, and an elegant presence — but do not want to compromise on the efficiency, lightness, and comfort that aluminum provides. This system is designed for those seeking a distinctive style with character, capable of adding personality to any space without sacrificing thermal performance or everyday comfort.

Its main appeal lies in its appearance: a design inspired by the aesthetics of traditional steel, reinterpreted with the technology and precision of CORTIZO. This allows the windows and doors to bring a sophisticated and contemporary touch, ideal for modern homes, lofts, character renovations, or projects where industrial aesthetics play a central role. It is a series that immediately transforms the feeling of a space, offering a perfect balance between elegance, sobriety, and personality.

Beyond its appearance, ALU STEEL offers all the advantages of a high-end system. Aluminum ensures smooth, lightweight, and long-lasting operation, avoiding the weight and limitations of real steel. This results in a more comfortable user experience, reduced maintenance, and a cleaner, more efficient installation. In addition, it provides a level of insulation capable of keeping the home more stable against outdoor temperatures, creating quiet, warm, and comfortable living spaces.

Its versatility is another of its great strengths. ALU STEEL fits perfectly into projects where a bold style is desired, while also adapting to more neutral environments that need a design touch to elevate the overall aesthetic. It allows for the creation of elegant compositions, with or without transoms, enhancing that highly sought-after industrial look without losing harmony with the rest of the home.

With ALU STEEL, your home gains style, character, and comfort in a single installation. Do you love industrial aesthetics? This is the system that brings it to life — without compromising on anything.

Exclusive industrial aesthetics that no other series can replicate

While most systems opt for minimalist lines or traditional profiles, ALU STEEL offers a design inspired by architectural steel, featuring straight, sober, and character-filled profiles. It is the only series that delivers that highly sought-after industrial look without resorting to real steel frames, which are significantly heavier and more expensive.

All the style of steel with the lightness and comfort of aluminum

Compared to series such as COR 60 or COR 70, which prioritize efficiency or minimalist aesthetics, ALU STEEL combines the design of a robust material with the typical ease of handling of aluminum. This translates into smoother operation, reduced maintenance, and a far more practical installation than any solution made from genuine steel.

Strong visual character without compromising interior comfort

Many systems are designed to maximize glass surface area or to visually disappear; ALU STEEL, by contrast, brings presence and design without compromising thermal efficiency or acoustic insulation. It is an ideal alternative when personality is desired without sacrificing comfort and well-being.

Greater design versatility thanks to its muntin-style compositions

Unlike standard systems, ALU STEEL allows you to play with transoms and internal divisions to create industrial-style compositions that personalize the space. It is perfect for those who want the window to be a decorative feature as well, not just a functional enclosure.

Technical details

Inspired by traditional designs, the new Alu-Steel system combines the outstanding performance of aluminum with the more classic aesthetics typically associated with steel. With a visible section of just 72.5 mm, Alu-Steel stands out as an ideal solution for both renovation projects and new builds, available in straight and chamfered versions.
