Profile

Who we are

欧之伦五金集团有限公司 · Ouzhilun Hardware Group Co., Ltd. is a hardware manufacturer based in Zhejiang, China, producing fittings for aluminium and PVC window and door systems.

Our mature, production-proven range covers aluminium and PVC door locks, tilt-and-turn (inner casement-tilt) hardware, curtain-wall fittings, thermal-break accessories, hinges, crescent locks, casement handles, two-point locks and transmission locking hardware — twenty-seven series in total.

Products are sold across China and exported to Europe, the Americas, the Middle East and Southeast Asia. We work on the principle that quality is the foundation a hardware business stands on, and that design capability is what keeps it moving — which is why both are kept inside the company.

Principles

Quality first, design always moving

Our operating principles are simple to state and demanding to keep: treat customers honestly, earn confidence through quality, keep innovating, and pursue the highest standard in both product and company.

In practice, that is expressed as an integrated manufacturing chain, a stable catalogue of production-proven series, and tooling kept in-house so a repeat order is the same product as the approved sample.

See the manufacturing chain
  • Integrated in-house production — six stages from design to assembly.
  • Wide, system-matched range — 27 series for aluminium and PVC systems.
  • Quality management — ISO 9001, with products tested by national quality supervision authorities.
  • Export experience — supplying Europe, the Americas, the Middle East and Southeast Asia.
  • Open to development work — OEM and ODM programmes, including special requirements.
