Overseas service support includes agents or branches and participation in the Eurocoat Exhibition, but no overseas warehouse or showroom is reported. Financial records are identified for 2023–2025, but no usable financial performance details are provided. A BV audit is listed with validity from April 20, 2026 to April 19, 2027 and an evaluation result of 0; the meaning of this result is not explained.
