The M-series M41 is a versatile steel door that provides a robust and reliable solution for industrial and commercial applications. As the base model within the M-series, it combines robust construction with extensive configuration options. The door is available as a single or double leaf and can be manufactured to open left- or right-handed, making it suitable for almost any installation.
The door features a durable double-skin construction with galvanised steel sheets, ensuring long-lasting performance and high resistance to intensive use. With a door leaf thickness of 75 mm and a weight of approximately 25 kg/m², the M41 provides a stable and robust closure.
For applications requiring additional acoustic performance, the door can be equipped with an optional sound insulation package. Thanks to its flexible design, the M-series M41 offers an excellent foundation for customised configurations and can be finished in any RAL colour, ensuring functionality and aesthetics are perfectly matched to the project.
The features above can be combined and tailored to your project. For more custom possibilities, or guidance in selecting the right door, our specialists are happy to help you find the best solution for your application.
M-series doors are suitable for integration in standard building façades, as well as in technical housings and industrial enclosures. They are commonly used in transformer and electrical rooms, mechanical spaces, data centres, laboratories and other facilities where safety, durability and performance are essential.
