YENA has long term lease contracts with 11 factories.
YENA Welding engineers have full control on the procedures and the fabrications.

We are flexible with order sizes.
Throughout the years we had contracts between 1000 € to 2,050,000 €.

For each project YENA assigns a project manager, and a QAE. (Quality Assurance Engineer)
The QAE works in the factory full-time during the project.

YENA engineers can support our clients to draft an ITP based on the project.
However final ITP should be approved by the client.

We have 2 full-time IWE, 2 contracted IWE and 7 welding engineers working in the contracted factories.

Yes, we also can serve our clients with design services. (TEKLA, STATICA, and ACAD)

This varies on each project, for example, YENA previously managed to engineer, produce, and deliver a very urgent project of a tank terminal in Amsterdam within 20 days.
3 days – TEKLA layouts & fabrication drawings.
2 days – material procurement
8 days – Steel fabrication
2 days – Galvanizing
5 days – Truck delivery and Customs operations in Netherlands.
