Our company
We set out with the vision of producing modern, durable and innovative composite solutions for industry.
Our story
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. Holding ISO 9001, ISO 14001 and ISO 45001 certificates and product conformity certificates, 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. Within this industrial group, which brings together more than 25 industrial companies across automotive, energy, and construction, FRP Line Composite plays a strategic role in composite manufacturing.
Using advanced composite material technologies, to provide light, durable, corrosion-resistant and long-lasting solutions to our business partners in the industrial, infrastructure and commercial sectors; and to answer the needs of these sectors with innovative pultrusion profiles, composite sheets, SMC-BMC parts and grating systems.
To become one of the world's respected brands in composite production technologies by carrying the trust and technical competence we have gained in Türkiye to the global arena. To become an environmentally friendly and innovative industrial enterprise that sets the quality standards of the sector with sustainable production, R&D investments and digital transformation.

Our principles
Fundamental principles that reflect our operational realities
Every product is an engineering project. We design our solutions around values calculated for the conditions of use, the mechanical requirements and the chemical environment.
Composite products resist corrosion, which reduces the need for frequent replacement and for maintenance downtime. We weigh material choices and production processes from that perspective.
Every project's conditions are different. We settle dimensions and application details together with our customer, according to the conditions of use.
Our promise is as strong as our products. Adherence to delivery deadlines and after-sales support are integral parts of our corporate culture.
Share what your project needs, and the FRP Line Composite team will work through the right composite solution with you.
