The DuoFlex frames, which were launched in Belgium in 2012, are a success. The steel frames are frequently used in offices, hospitals and nursing homes.
The success of the DuoFlex frames is due to the quality and flexibility of the frame.
The unique mitre joints create a very stable construction and the assembled frames form a single whole with the wall. The frame is adjustable to the wall size, which makes it suitable for traditional wall openings.
The DuoFlex frames are manufactured from steel plated in zinc using the Sendzimir process and have a wall thickness of 1.5 mm. After pre-treating the steel frame profiles, an electrostatic method is used to apply a scratch-resistant and impact-resistant powder coating, which is then enamelled. This means that the frame provides long-lasting and high-quality protection with no need for further painting.
