Today we talk about the difference between non-standard aluminum profile and standard aluminum profile. Since aluminum profiles are mostly produced by aluminum extrusion technology, why distinguish between non-standard and standard?
In general, aluminum profiles are a very popular and common material in modern industrial production. They can be used to build workbenches, assembly lines, fences, shelves, etc., and can also be used as radiators, cabinets, fan blades, etc.
Standard aluminum extrusions have a fixed cross-sectional size and structure. It is designed with slots and holes. After some simple processing, it can be built into various frames such as workbenches and fences with corner codes and other accessories. Basically, it can be used universally. Therefore, a standardized production model can be adopted.
Non-standard aluminum extrusions are mostly used as radiators, cabinets and other equipment components. They must be designed and produced according to specific customers, specific cross-sectional dimensions, tolerance requirements, and surface requirements of specific equipment, so standardized production is impossible. We can only open mold production according to different needs, so we simply classify them as non-standard profiles.
Other national advanced standards include: EU EN12020-2 "6060 and 6063 Aluminum and Aluminum Alloy Precision Profiles Part 2: Dimensions and Shape Allowable Deviations", EN755-2 "Aluminum and Aluminum Alloy Rods, Tubes, and Shapes-Mechanical Properties", American ANSI H35.2 "American Aluminum Material Dimension Deviation Standard" and Japanese JIS H4100 "Aluminum and Aluminum Alloy Extruded Profiles" and other standards are 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, etc.
