Audit information identifies TÜV Rheinland, but the evaluation result is recorded as 0 without an explained grading scale.

Supplier typeThe supplier is identified as TIANJIN FRIEND STEEL TUBE CO., LTD., a China-based limited company in Tianjin established in 2009. The records also describe it as a combined entity and, in one slice, as a trading company, while its product description identifies steel-pipe and scaffolding manufacturing activities.

CertificationsThe supplier reports ISO 9001:2015 and ISO 14001:2015 certifications. A TÜV Rheinland audit is also recorded with a report period from March 19, 2025 to March 18, 2026, although the audit result is listed as 0 without interpretation.

After-Sales capabilityThe supplier explicitly states that it has a devoted and enthusiastic after-sales service team. It also claims to provide systems for delivery, invoicing, settlement, transportation, and goods storage, supporting a broader service process.

Production capacityThe supplier reports five production lines and annual scaffolding-tube productivity of 5,000 tons, with stated order fulfillment within 15 working days during both peak and off-peak seasons. Its product description covers high-frequency welded pipes, galvanized steel pipes, and scaffolding products, providing explicit evidence of operating production capability.
