Building aluminum alloy profiles shall comply with the above standards, that is, as long as they are aluminum alloy profiles used in the construction industry, their products must be produced and controlled according to the mandatory standards of gb5237.1 ~ 5-2008 and gb5237.6-2004.

(2) GB / t6892-2006 industrial aluminum and aluminum alloy extruded profiles for general use

Industrial aluminum profiles refer to other aluminum extruded profiles except aluminum profiles for building doors and windows, curtain walls and indoor and outdoor decoration. Except that individual products implement their special standards, most of the Executive Standards are GB / t6892-2006 general industrial aluminum and aluminum alloy extruded profiles. The products are mainly used in aerospace, transportation, rail vehicles, electronic appliances, sports equipment, radiators Decoration, power and energy, petrochemical industry, machinery manufacturing and other industrial fields.

(3) GB / t26014-2010 aluminum alloy decorative profiles for non construction purposes

Non architectural aluminum alloy decorative profiles refer to aluminum alloy hot extruded profiles for decoration with the main purpose of improving visual effect. If there are special requirements for the dimensional deviation of decorative profiles, it shall be indicated in the contract. If there are no special requirements, it shall comply with the provisions of general grade in GB / t14846-2008 dimensional deviation of aluminum and aluminum alloy extruded profiles. The products are mainly used in vehicle interior and exterior decoration, home appliance accessories, kitchen appliances, electronic appliances, interior decoration, medical instruments, instruments, office facilities and other fields.

(4) GB / t14846-2008 dimensional deviation of aluminum and aluminum alloy extruded profiles

Another standard for industrial aluminum alloy profiles is GB / t14846-2008 aluminum and aluminum alloy extruded profiles dimensional deviation. However, this standard is only for the extrusion size of industrial aluminum profiles. If there are only requirements for size, it can be produced according to this standard. Other requirements shall be in accordance with GB / t6892-2006.

(5) Foreign advanced standards

Foreign advanced standards include: European Union en12020-2 6060 and 6063 aluminum and aluminum alloy precision profiles Part 2: allowable deviation of dimensions and shapes, en755-2 aluminum and aluminum alloy rods, tubes and shapes - mechanical properties, American Standard for dimensional deviation of aluminum materials ansih35.2 and Japanese jish4100 aluminum and aluminum alloy extruded profiles, It is mainly applicable to some special customers or international large building curtain wall companies in well-known buildings, landmark buildings and projects supervised by foreign projects.

(6) Enterprise standard

If there are no national standards, industrial standards or local standards for the products produced by an enterprise, corresponding enterprise standards shall be formulated as the basis for organizing production. The enterprise standards shall be filed with the local technical supervision bureau according to the specified procedures. The quality and technical supervision system is a localized management. After taking samples, the market supervision and random inspection should go to the local quality and Technical Supervision Bureau where the enterprise is located to review the filing standards before determining whether it is qualified. The manufacturer can know that the products are supervised and spot checked in advance, actively follow up the product inspection process and results in advance, and take corresponding treatment measures. Such as small materials, non building profiles, decorative profiles and export profiles.
