Local domestic production of prepainted 3003/3105 aluminum coils optimized for European standard gutter profiles. Local warehousing across Turkey enables ultra-fast delivery for regional manufacturers. PVDF coating lines built for Mediterranean UV resistance, full compliance with EU EN485 standards.

Limitation

Higher unit price vs imported Chinese coils; minimum order tonnage is higher, less friendly to small gutter workshops.

Gutter-Core Strengths

Custom slitting service tailored to small gutter production lines; offers mixed alloy small batches. Supports all trade terms (FOB Mersin, CFR Istanbul). Widely used by regional rural residential gutter projects across Anatolia.

Weak Point

Limited fluorocarbon coating production capacity; mainly supplies PE standard-grade coils.
