Company
An industrial manufacturer, not a contractor.
DUSO produces corrugated metal duct systems for post-tensioning: factory-made sheaths, connection couplers, and the machines that make them — including mobilisation to the project site.
01
Positioning
The company is organised as a manufacturer and equipment supplier to post-tensioning contractors, system holders and infrastructure projects. It does not present itself as a general construction contractor.
02
Where production happens
Factory production is based in Türkiye. On-site production is offered internationally where the project requires it. Delivery can be arranged worldwide subject to quotation.

How to work with DUSO
Start from a published size, a drawing package, or an on-site production brief. Engineering responds with a technical quotation — not a generic brochure follow-up.
