Hansen Millennium®. Exclusive in the Netherlands

PRO STEEL is currently the only party in the Netherlands with Hansen Millennium® - the Danish aluminum system with the slimmest profiles in the world. This is not a standard steel look. It is an architectural system, designed as a modern successor to the narrow steel windows of the early 20th century.

As a result, the product remains scarce - not every supplier is allowed to carry it, and not every project fits this level. For villas, monumental renovations, and new builds where the frame should almost disappear, this is now available in the Netherlands.

28.5 mm profile. Maximum glass, minimal frame.

The visible window profile is only 28.5 mm. In comparison: standard aluminum frames often show 50 to 70 mm of frame. With Millennium, almost the entire surface is glass. Daylight, sightlines, and facade rhythm noticeably change as a result.

Technically, the system is built for real construction practice, not just for a showroom photo. Hidden hinges and hidden drainage keep the facade calm. Tilt-and-turn is possible up to approximately 2.5 m² and 100 kg. Glazing up to 60 mm: HR++ or triple. Round, arched, and angular shapes can be in the same system.

Narrow profile, high insulation

Old steel windows lose heat and sweat. Millennium maintains the narrow steel appearance but breaks the cold bridge over the full length of the profile.

With triple glazing, a U-value of up to 0.80 W/m²K is achievable. That is restoration that looks like it did before and lives like it does now.
