Turkey's Premier Marine Steel & Fittings Exporter

Seaway Ship Services operates as Turkey's largest stockist and export consolidator for marine-grade steel pipes, structural profiles, flanges and pipe fittings — giving UK and EU shipyards direct access to Europe's second-largest and the world's eighth-largest steel producing nation. Turkey's steel sector operates at 51.8 million tons of annual capacity across 12+ mills holding international shipbuilding society approvals, supplying every major grade demanded by classification societies including ABS, DNV, Bureau Veritas and Lloyd's Register.

The combination of domestic raw material supply chains, scale manufacturing, and preferential trade access under both the EU Customs Union and the UK-Turkey Free Trade Agreement creates a structural cost advantage of 25–40% versus Western European mill alternatives. For UK and EU shipyards, dry docks, offshore fabricators and piping contractors — where steel constitutes the single largest material cost line — Turkish supply represents an immediate and proven route to margin improvement without compromising certification standards.

Every product we stock and export is accompanied by full EN 10204 3.1 mill certificates, classification society test reports, and complete material traceability documentation. Our logistics team handles A.TR movement certificates, customs pre-clearance and consolidated packing to the specific requirements of shipyard receiving departments. Minimum order from one ton — mixed pallet accepted on first enquiry.
