Service capability is supported by written procedures, records, 18 qualified service suppliers, and corrective/preventive-action procedures. However, it reports no overseas warehouses, showrooms, agents, or branches, and lists zero countries with overseas services. Financial information is only represented by years covered and does not provide sufficient evidence for a financial assessment. Customer evidence is limited to OEM service for well-known brands and participation in the IWF Woodworking Show.

Its stated business scope includes material manufacturing, mechanical and electrical equipment manufacturing and sales, metal materials, composite materials, chemical products, and hardware retail, indicating a manufacturing-oriented supplier with a broad industrial product scope.
