Profiles Are Objects With A Certain Geometric Shape Made Of Iron Or Steel And Materials With Certain Strength And Toughness Through Rolling, Extrusion, Casting, And Other Processes. This Type Of Material Has A Certain Appearance Size, A Certain Cross-Section Shape, And Certain Mechanical And Physical Properties. Profiles Can Be Used Alone Or Further Processed Into Other Manufactured Products, Often Used In Building Structures And Manufacturing Installations. Mechanical Engineers Can Select The Specific Shape, Material, Heat Treatment State, Mechanical Properties, And Other Parameters Of The Profile According To The Design Requirements, And Then Divide The Profile According To The Specific Size And Shape Requirements, And Then Further Process Or Heat Treatment To Meet The Design Accuracy Requirements.
