Istanbul: The Strategic Gateway for Coated Steel

Istanbul stands as the heartbeat of Turkey’s industrial prowess, bridging the metallurgical demands of Europe and Asia. As a premier Coated Steel Supplier and Factory operating within the reach of Istanbul's strategic industrial zones like Gebze and Dilovası, we leverage the city's unparalleled logistics network. The local steel industry has undergone a massive transformation, shifting from basic production to high-value Coated Steel solutions including Aluzinc, Galvalume, and specialized Zinc-Magnesium coatings.

In the modern Istanbul skyline, from the rapid residential expansions in Başakşehir to the heavy industrial complexes in Hadımköy, coated steel is the backbone of durability. Our factory integrates advanced AI-driven manufacturing processes to ensure that every coil and sheet meets the rigorous environmental standards of the Marmara region, characterized by high humidity and saline air near the Bosphorus.
