01 — About

One mill.
A new front door.

Gem & Co doesn't run a furnace of its own — it exists so that buyers outside Turkey can reach one that already runs at full capacity.

The mill traces back to 1948, when Güven Bakır İş ve Koll. Şti began rolling copper sheet in Kahramanmaraş. Coil and strip production followed in 1993, and in 1997 the business incorporated as Gemciler Güven Metal San. ve Tic. A.Ş. — the company that still runs the line today.

Gem & Co Ltd is the group's answer to a simple, recurring question from buyers abroad: can we order this directly, in English, on UK terms? It is the trading company that sits between a British or European purchase order and a Turkish rolling line — no intermediary distributor, no re‑quoted margin.

"To be the international first choice in copper coil, sheet and flat‑bar production."— Gemciler Güven Metal, company vision

The site you're looking at is a working draft. The mill, the history and the product range are real; the storefront around them is still being built.

Produced to EN specification, not just to sample.

Gemciler's rolling programme is produced to EN 1652 and equivalent copper & brass sheet, strip and circle specifications, under an ISO 9001:2015 quality system and its own R&D centre. Gem & Co's role is to carry that paperwork with the shipment, not around it — mill certificates travel with every order.
