The doors are manufactured with the METRA FLEX system. The profiles are made of aluminium alloy EN AW 6060 (EN 573-3 and EN 755-2) with temper designation T5 according to UNI EN 515, extruded in compliance with the tolerances according to UNI EN 12020-2. The frames are made by assembling two extrusions suitable for compensating for masonry thicknesses varying from 90 mm to 215 mm. The screws fixing the frame to the masonry and those joining the compensating profiles are not visible, but concealed by specific gaskets. The 45° corner joints are made by means of mechanically-drawn corner cleats, equipped with an aluminium button. The profiles of all frames must allow the use of alignment corner cleats for the correct corner joint. The profiles are painted with polyester powder coating. Gaskets and finishing gaskets shall be in EPDM.
