[0002] Profiles refer to long materials with a specific shape on the cross-section. Common materials include aluminum alloy, steel, copper, etc. Compared with traditional square pipes and round pipes, profiles have stronger bearing capacity and external force resistance, and can effectively improve the service life in fields such as construction and machinery.

[0003] Profiles play a very important role in the construction field. For example, aluminum alloy profiles are commonly used in doors, windows, curtain walls, etc., which can improve the sound insulation, heat insulation, and fire resistance of buildings.
