DMF International manufactured and installed some specialised high speed roll doors in an unusual application under a mezzanine flooring structure. We were requested by the client to provide a sealing solution, for a company who produce specialty safety equipment and fast print safety signs. The design brief was to create a sealed working area under a mezzanine floor, that created an area housing specialised printing equipment. Access was critical to be maintained into the work area, and yet minimised dust entry was necessary to protect the environment.

DMF designed and modified, then installed 3 units of Series RL3000 high speed roll doors, with the drive roller system being housed behind the front structural purlin, resulting in a very neat finished door system. The open spaces remaining on each side of the doors were enclosed using specially fabricated and powdercoated infills.

The rapid roll doors were each about 5m in width, and are activated by pushbuttons, and come with full safety sensors. This width will allow movement of large products in and out of the printing area.

David Kuo, Operations Manager, said “the doors were a great solution and I am very happy with the result, and final appearance”.

These specialised high speed doors are custom manufactured to size by DMF in Sydney, and come with many options, but can also be customised to suit demanding applications. Contact us today for an assessment for your site, by emailing to
