Varnishing: A rounded edge guarantees the same thickness of varnish during varnishing, preventing cracking and peeling of the varnish.
Safety: Sharp edges on sheet metal can be dangerous for workers handling the metal. Radios help reduce the risk of injury.
Aesthetics: Radii can improve the appearance of a product or structure. Sharp edges can look unaesthetic and careless.
Durability: Sharp edges can lead to wear or damage to products that come into contact with the sheet metal. Radii can extend the lifespan of these products.
Mechanical Properties: Radii can improve the mechanical properties of the sheet metal, particularly its strength and resilience.
Overall, it can be said that radii on sheet metal have a positive impact on safety, aesthetics, durability, and the mechanical properties of the sheet metal and the products made from it.
