Aluminum alloy standard profiles refer to aluminum alloy extrusion products made according to national standards, used in the construction and other industrial fields. Here are some detailed information about aluminum alloy standard profiles:
1. **National Standards**: In China, the production and application of aluminum alloy architectural profiles follow the national standard GB/T 5237.1-2017 "Aluminum Alloy Architectural Profiles - Part 1: Substrates". This standard specifies the requirements for aluminum alloy architectural profiles, including material composition, size specifications, surface treatment, etc.
2. **Scope of Application**: This standard applies to aluminum alloy extruded profiles used in construction, which are commonly used in the manufacture of building components such as doors, windows, and curtain walls.
3. **Product Requirements**: The standard provides a detailed description of the performance requirements for aluminum alloy profiles, such as strength, corrosion resistance, surface quality, etc., and offers corresponding test methods and inspection rules.
4. **Packaging and Transportation**: There are clear regulations on how to mark, package, transport and store, as well as how to provide quality certification and order form (or contract) content.
5. **Updates and Substitutions**: With the development of technology and changes in market demand, national standards are constantly updated. For example, the GB/T 6892-2006 standard replaced the previous GB/T 6892-2000 and GB/T 19347-2003 standards to meet new requirements.
6. **English Version of Standards**: For the convenience of international trade and communication, these national standards usually have corresponding English versions for international users to understand and follow.
In summary, aluminum alloy standard profiles are produced according to relevant national standards with uniform quality and performance requirements, widely used in construction and other industrial fields. When purchasing and using these profiles, understanding and following the relevant national standards is very important.
