Thailand finished steel production share by mill
SSI ~36% of HRC
Sahaviriya Steel Industries (SSI) dominates Thailand's hot-rolled coil (HRC) output with roughly 36% of installed capacity per company filings and ISIT mill survey. G J Steel (GJS, Hyundai Steel-affiliated since 2019) holds approximately 20% of HRC share, with G Steel (GSTEEL), Tata Steel Thailand (NSM, SCSC, SISCO long-product mills), and Millcon Steel covering the long-product and downstream segments. The aggregate Thai mill landscape is electric arc furnace (EAF) dominant at roughly 10 million tonnes installed capacity, but apparent consumption of 16-17 million tonnes leaves more than 10 million tonnes of imports per year — the structural import gap that drives anti-dumping politics.

What not to do with it
Approximate shares of installed finished-steel capacity. HRC mills dominate flat-product slice; long-product mills concentrated in Tata, Millcon, regional EAFs.
