DLSS Manufacturing is a supplier of architectural sheet metal and engineered metal building components.
Unlike painted metal finishes, patina naturally "heals" itself with exposure to the elements. Scratches and discoloration will weather out naturally. Weathering is largely dependent on the dwell time of moisture on the surface of the metal. Ultimately the patina acts as a barrier to corrosion for generations.
DLSS guarantees that the surface will not “check” or rinse off under normal natural weather conditions for a period of one year, after which the natural patina formation will have taken over. Under normal conditions the surface aspect will mature for the entire life of the copper.
