Standard aluminum strips are mass-produced with fixed dimensions and specifications, making them readily available and generally more affordable. They are suitable for common applications where specific requirements are not needed. On the other hand, custom-made aluminum strips are manufactured according to specific customer requirements, including size, shape, thickness, and alloy type. This customization allows for unique applications and better performance in specialized environments but may come at a higher cost and with longer lead times due to the bespoke manufacturing process.
