Door frames are made of specially molded aluminum profiles with a wall thickness of 2-3 mm. The doors are telescopic, allowing adjustment depending on wall thickness, with integrated aluminum jambs. Aluminum door frames are manufactured with electrostatic RAL paint or natural matte galvanized finish. The special door seal housing, hinge bearing and corner joints of aluminum door frames allow for connection with fittings at an angle of 45 degrees.
Pressed door wing thickness is 42 mm at a minimum. All door recesses (all 4 sides) are coated with special aluminum C profiles to provide impact and water/moisture resistance. Side recesses miay also be coated with PVC bands upon request. Glass wings may also be installed on adjustable aluminum door frames instead of laminate wings. Glass wings should be manufactured of 8, 10, 12 mm thick tempered and ground glazing, depending on the size of the wing.
