SummaryTIANJIN FRIEND STEEL TUBE CO., LTD. is a China-based limited company established in 2009 and located in Tianjin. It offers steel pipe and scaffolding products, reports five production lines, annual scaffolding-tube productivity of 5,000 tons, and stated order lead times of within 15 working days in both peak and off-peak seasons. The supplier states that it can handle special customer requirements and customized processing using imported materials, and that it maintains a dedicated after-sales team. ISO 9001:2015 and ISO 14001:2015 certificates are reported. Export sales are stated at 71%–90%, with exporting beginning in 2021. However, several capabilities remain unverified, including contract manufacturing status, inventory services, overseas facilities or agents, ODM/OEM, SDK-related R&D, and customer case details. 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.

Customization capabilityThe supplier explicitly states that special customer requirements can be handled and that imported materials can be used for customized processing. However, formal manufacturing-contract status and ODM/OEM service availability are marked unknown, so the evidence supports customization claims but not the broader service categories.
