Steel systems

Narrow profiles for stylish solutions!

Steel windows possess high static properties, which is why they are particularly suitable for heavy-duty use and high safety requirements. The superior static properties of steel as a material allow perfect construction of large-format windows, with very fine profile widths at that. Even when restoring old buildings, Jansen’s steel windows meet the requirements for design and vision.

Steel is a material which is extremely strong and resistant to mechanical damage. That is why Jansen’s profile systems are suitable for heavy-duty operation: busy traffic, industrial buildings, schools and hospitals, sports and entertainment centres, administration and public buildings. With approximately 210 kN / mm2, steel has the highest elasticity module, compared with all others, used in construction on a massive scale. The specific characteristics of this material reveal fascinating capabilities in static measurement, fire protection, anti-burglary constructions and noise insulation.Jansen’s wide range of products boasts also thermally insulated steel systems and profiles for doors, portals, windows and facades.The preliminary workshop preparation of the elements ensures easy, fast and efficient assembly. The wide range of profiles is supplemented by a complete set of lining and ancillary items for production.

With Janisol® and Economy®, we at Glass and Aluminium Fusion Ltd. offer various options for steel interior and exterior windows. The small share of the frame, and the large share of the glass meet important architectonic requirements, as far as the building’s visual elegance and transparency are concerned.
