Speedor Maxi

Large fabric door with twin-layer fabric for strength and insulation.

Our largest, wind resistant high speed industrial door.

The Maxi can be automated to provide the energy saving benefits attained by other products in the range. As the Maxi is used predominately as an external door it has exceptionally good wind resistance and can be designed for wind speeds of 115MPH.

Travelling at a generally slower speed than other doors in our range, it still opens up a very large opening in a short time.

The whole system is extremely robust and capable of many operations every week for year after year, it’s design and construction are commensurate with a high level of duty.
