We set out with the vision of producing modern, durable and innovative solutions for Türkiye's industrial storage needs.
The organization began composite manufacturing in Izmir in 2002 under the Fiberteknik name, starting in a 100 m² workshop with GRP storage tanks and automotive parts. In 2005, it moved to its 4,000 m² facility in the ITOB Organized Industrial Zone and specialized in food storage, chemical, and treatment tanks.
Today, FRPLine Composite Technologies Ltd. Co. produces industrial solutions through filament winding and spray-up, pultrusion, grating, sheet, SMC, and BMC methods. Backed by ISO 9001:2015 and CE certifications, the company has manufactured more than 10,000 GRP tanks since its foundation and exported its products to Europe, Asia, Africa, Latin America, and Australia.
At the end of 2025, the company joined Karabağlı Holding and continued production as Fiberteknik and FRP Line Composite Ltd. Co.
