I'm pondering spending 25-30000 on an outward-opening folding door for the machine hall. Alternatively, welding together swinging doors from square tubing with sheet metal cladding and Styrofoam as insulation. In the latter case, where can one find some sturdier hinges? Question B, I seem to recall there are hinges that have some sort of ramp that lifts the door a few cm when opened. Do these exist, and if so, where?
If you are going to buy.
For best insulation, Prido Ecolid, they are frameless with minimal cold draughts that you get in a door with a frame. They are significantly lighter as well.
Everyone who manufactures sectional doors has lifting hinges.
Prido has hinges that are screwed on, others are available for welding.
Lifting can only be used for external doors, but you might already know that.
