roll-up door / exterior / industrial / high-speed
Puertas Angel Mir
The outside frame is a self-bearing chassis made of galvanized steel sheet, formed by two transoms, that work as guides and supporting base (the corners that rub the leaf are protected by industrial brushes that reduce the rubbing and increase water/air tightness).
There is an upper crossbeam with a drawer shape.
The aluminum rolling up shaft is located inside the platform and assembled upon bearing supports. The curtain is rolled up on the shaft.
It is a self-bearing structure and does not need significant fixings on the building but just simple supporting squares.
