SummaryThe supplier is a limited, combined company with 82 employees and a valid import/export license. It manufactures metal structures and reports annual steel-structure productivity of 50,000 tons, supported by CNC cutting, welding, shearing, drilling, spark-cutting, and shot-blasting equipment. Quality evidence includes 100% finished-product inspection, 15 quality assurance and quality control inspectors, and documented procedures for supplier assessment, corrective actions, and complaint handling. The supplier supports customization from samples and designs and provides OEM services, but does not provide ODM services or an SDK. It offers overseas services in Russia, accepts FOB and CIF quotations, and reports peak-season lead time of one month and off-season lead time within 15 workdays. No overseas warehouse, showroom, agent, branch, or offline trade-show participation is reported. Certification holdings and customer cases are not provided.

Supplier typeThe supplier is identified as a combined company organized as a limited company, with 82 employees and no stated parent-company affiliation. It also holds a valid import/export license, supporting its classification as an operating manufacturing and export supplier.

After-Sales capabilityThe supplier has documented procedures and records for handling customer complaints, corrective and preventive actions, and service-capability assessment. However, it reports no overseas warehouse, showroom, agent, or branch, which limits documented overseas service infrastructure.

R&D capabilityThe supplier reports one year of total R&D engineer experience and does not provide ODM services or an SDK. These statements do not demonstrate strong independent product-development or software-integration capability.

Production capacityThe supplier reports steel-structure productivity of 50,000 tons and operates equipment including CNC cutting, welding, shearing, drilling, spark cutting, and shot blasting. It also reports one production line, 6–10 quality-control staff, and off-season lead time within 15 workdays, providing explicit evidence of manufacturing capacity.

Customization capabilityThe supplier explicitly supports customization from samples and designs and provides OEM services for popular brands. It does not provide ODM services, so the evidence supports manufacturing customization but not independent ODM development.
