Who We Are

A Composite Manufacturer since 1977

Zenginler İmalat was founded in 1977 by İbrahim Zengin in Sakarya, Türkiye. From the outset it specialised in polyester and glass fibre reinforced polyester (GRP) composite parts. In 1999 it moved into the plant it occupies today.

Operating in six industries — led by automotive, rail, machinery and energy — the company offers a broad product range using hand lay-up, RTM, vacuum infusion and pultrusion.

With the experience gathered over the years and a policy of continuous investment, Zenginler İmalat serves Türkiye's leading OEMs without interruption.
