Thai Coated Steel Sheet Co., Ltd., or TCS, is the first company in Thailand to produce electro-galvanized steel sheet in coils. It was founded in 1992 as a joint venture between SSI and three Japanese companies, namely NKK Corporation, Marubeni Corporation, and Itochu Corporation.

TCS has been granted investment privileges by the Board of Investment to produce galvanized steel sheet by electrolytic coating process. Costing 2.45 billion baht, or approximately US$100 million, TCS’s plant began production in February 1994 with a capacity of 180,000 tonnes per year. The main raw material used is cold-rolled steel sheet.

Electro-galvanized steel sheet is more resistant to corrosion than ordinary cold-rolled steel sheet. The smoothness of the surface and the chemicals applied to it facilitate the coating process. The end-product is ideal for work that demands an attractive finish, such as automobiles, computers, and electrical appliances that include video players, televisions, refrigerators, and washing machines. Consumer demand is causing manufacturers to rely more upon galvanized steel than ever before for products that are both beautiful and durable.
