SummaryThe supplier is identified as a combined company and a professional technical supplier focused on construction-related products and steel-structure manufacturing. It offers sample-based customization, full customization, 3D software design, ODM, and OEM services, and reported new products during the past year. Production information includes prefabricated steel structure capacity of 100,000 square meters, steel structure frames of 5,000 tons, and other fabricated steel structures of 2,000 tons. Quality-related evidence includes CE certification, ISO 9001:2015 certification, documented inspection procedures, corrective-action procedures, complaint-handling procedures, and raw-material traceability.

After-Sales capabilityThe supplier has documented procedures and records for complaint handling and corrective and preventive actions, indicating an established service-response process.
