The upper rail is made of a double aluminium alloy profile EN-AW-6082 (GammaDoors's patent) and fixed to the supporting structures by means of bolts that allow perfect adjustment of both the plane and the alignment. This solution allows the flexibility to adapt to any structure, being able to move the fixings as needed.
The trolleys made with a steel body are solid and silent. The brushes, manufactured with 0.20 mm corrugated nylon filaments and stainless-steel strips, are designed to ensure optimal closure.
The 80 mm thicknes panel, in its classic version, with internal perimeter frame in galvanized steel profiles is covered with a double pre-painted steel sheet with an embossed or smooth finish.
An anti-crushing gasket is placed between the leaves, made with multiple chambers (GammaDoors's patent) in EPDM with hardness 70 "IRHD" and working temperature -25° + 100°C.
The hinges are made by processing an extruded aluminum profile (GammaDoors's patent), equipped with self-lubricating sintered bushings, galvanized steel pins with a diameter of 25 mm, fixed to the doors by counter plates and hidden bolts (not accessible when the door is closed) adjustable at full height.
