"Professional standards collection: aluminum alloy doors and windows and their profiles (2012)" contains the standards of aluminum alloy doors and windows and their profiles, including anodized profiles, thermal insulation profiles, aluminum alloy doors and windows, integrated aluminum alloy doors and windows, light metal rolling doors and windows, aluminum alloy wood grain profiles for construction, etc. The main technical differences between this part and gb5237.1-2004 are as follows: adding 6005, 6060, 6463, 6463a alloys, adding the mechanical shop here property requirements of 6005-t5, 6005-t6, 6060-t5, 6060-t6, 6463-t5, 6463-t6, 6463a-t5 and 6463a-t6, and specifying the property values of elongation A and a 50mm after fracture; - adding the definition of aluminum sunshine house circumscribed circle; ——In the mark, the name of the product is changed to "base material"; - the minimum nominal wall thickness of profile shall not be less than 1.20 mm except for the profiles which need elastic assembly such as pressure strip, gland and gusset plate, etc.; - the allowable deviation value of dimension is greatly modified. When using this part to order building door and window profiles, designers and users should correctly select the wall thickness size of the profiles according to the technical requirements on sale - women and technical specifications of the building where the doors and windows are located.
