Riveting also offers a cost-effective solution for FFU  manufacturing. The process requires minimal equipment and can be easily automated, reducing labor costs and increasing production efficiency. Additionally, the use of rivets eliminates the need for additional fasteners, such as screws or bolts, reducing material costs. Furthermore, riveting provides a aesthetically pleasing finish to FFU systems​ . The smooth and flush surface created by the rivet provides a clean and professional appearance, which is important in applications where the FFU  may be visible.
