Coatings come with a 3 year warranty against corrosion and rust to original owner. -Lifetime warranty against any manufacturing defects given to original owner. -We do NOT grind/polish our welds as some other manufacturers do. Grinding welds compromises the strength of the weld, and can lead to weld failure - especially critical in applications exposed to temperatures in excess of 1200°F. Such temperatures will also rapidly deteriorate the polished finish.
