PLATING.EARTH is a searchable directory of plating and surface treatment company and site records around the world.
The first survey snapshot, dated September 28, 2026, contains 1,639 verified processing company and site records across 125 countries and regions, from a survey covering 249 countries and regions. These figures count records, not necessarily distinct legal entities. Companies and sites located in Japan are excluded. Overseas sites of Japanese companies may be included.
Coverage is not exhaustive. Records describe the information available at the time of the survey and do not guarantee current operations, capabilities or certifications. Blank fields mean unconfirmed, not unavailable. Counts reflect research coverage and should not be interpreted as market size or a ranking.
The interface is in English. Some research descriptions and notes remain in their original language to preserve qualifications and avoid adding unverified claims. Updates will be reviewed before being incorporated.
