At J&E Companies we manufacture, market, and sell a range of custom double-wall, insulated walk-in doors used for HVAC industry applications. Various standard and custom door sizes can be manufactured in depths from 1” to 4”, with mitered corner/weld frames and with a thermal break option. The widths and depths are customized for each application and can be fabricated from 22 -16GA galvanized steel, cold rolled, and stainless-steel, and aluminum. In addition, viewports, custom hinges, test ports, and foam or mineral wool insulation is available as part of the custom manufacture of this product.
In the project above, we used a combination of turret punching, sawing and forming to fabricate the two faces of the doors. Insulation was then placed between the doors’ faces, which were then welded around the edges with the insulation secured between. An EPDM seal was also attached to ensure a tight seal when the door was in position. View ports were then put into the door as needed with glass inserted and sealed into the openings. The doors were then finished in one of several different custom colors using powder coating to ensure a tough, durable finish.
For each door, a thorough dimensional and inspection fit test was performed with a test rig to ensure that the door met customer requirements.
J&E delivers over 7,000 doors of this type annually, shipping typically in 2 weeks from the receipt of the order to various destinations around the USA. The doors are shipped in customized shipping crates to reduce the potential of damage.
