Raw Material and Semi Products

We are more than an import shop of scrap, pig iron etc. but we would diversify our value added functions as an operational fertile center to serve daily needs of melting steel plants like a convenience store.

For non-ferrous raw material, with the liquidation of our former Metal Div. and the company's policy, we've stepped out from all major non-ferrous business, except for the 'Zinc' metal. Therefore, our main activity would be focusing only on zinc metal ingot which is produced by Padaeng Ind. PCL., the sole Electrolytic Zinc Smelter in this region. Padaeng Ind. PCL has an annual production capacity of approx. 110,000 mt on Special High Grade (SHG) Zinc metals for supplies to G.I. Sheets, Pipes and general Galvanizers etc. and Zinc Alloys (ZA) to Die-casting manufacturers. We (Mitsiam) are ranking on the top 20 of Padaeng's shareholder-list.
