The current standard for aluminum alloy door and window profiles "Aluminum Alloy Building Profiles" GB/T5237-2008, its alloy grades, supply status, chemical composition, mechanical properties, and dimensional tolerances should comply with the current national standard "Aluminum Alloy Building Profiles Part 1: Base According to the provisions of 5237.1, the allowable deviation of the cross-sectional dimension of the profile can be selected as ordinary grade, and high-precision or ultra-high-precision grade should be selected when matching requirements are required. Among them, the materials are currently mainly used for doors and windows: 6063T5 and 6061T6. Mainly used in Europe: 6060T6
Wall thickness: Engineering aluminum doors and windows are implemented in accordance with "Aluminum Alloy Doors and Windows" GB/T8478-2008. Guangdong Galuminium Extrusion Co. Ltd. produces quality Aluminum outside-hung window. Aluminum outside-hung window The wall thickness of the main profiles used for the main force-bearing members such as outer door and window frames, sashes, and sash frames should be determined by calculation or experiment. The minimum actual wall thickness of the main stressed base material of the main profile, the outer door and window should not be less than 2.0mm, and the outer window should not be less than 1.4mm. Profiles that require elastic assembly such as beading, glands, and gussets are generally within 0.8-1.2mm between. When checking the size deviation, take 1% of the profile roots in each batch, not less than 10 roots.
