Sharp edges make it hard for paint and protective coatings to build up an even film, so those spots often corrode first.
A controlled edge radius helps coatings adhere, extends durability, and helps meet demanding finishing specs.
N.KO Machines round edges fast and repeatably on steel parts across a range of sizes and thicknesses.
Coatings naturally thin out on sharp corners. Rounding the edge before paint or galvanizing improves coverage and lowers the risk of corrosion failures down the line.
Edge rounding pays off especially on parts headed for the outdoors, humidity, or harsh service conditions.
