Ottostumm W65 - French Exterior Steel profile

French exterior steel windows


French exterior steel windows are an ideal choice for any home or building. These windows are stylish, durable and energy efficient making them a great option for any property.

Furthermore, W65 steel windows are made from a variety of materials, but steel is by far the most common. Steel is known for its strength and durability, making it an ideal choice for exterior windows.

Still, steel frames are highly insulated and provide excellent thermal protection from the outside elements. This helps to keep your home cool in the summer and warm in the winter, reducing your energy bills.

Moreover, W65 profiles are made from 2 mm cold-formed zinc-magnesium steel, which grant a high internal and external protection against rust and atmospheric corrosion.

Compared to conventional zinc coated steel profiles, this special dual coat is welder friendly and does not form gas bubbles in the weld seam.

In our opinion this system is an ideal solution for large glazing in milder climatic zones and with its 65/72 mm profile depth an extremely strong framing material for security windows.
