Process & Facilities
SSI’s maximum production capacity for hot-rolled steel sheet is 4 million tonnes per year. This is the greatest single-facility capacity in Southeast Asia.
The process begins with high-quality steel slab. One piece of slab, weighing 5-32 tonnes and 160-250 mm thick, is heated in a furnace until it reaches a temperature of 1,250°C. The heated slab is rolled until it becomes a steel sheet of 1.0 – 19.0 mm thick and 750 – 1,550 mm wide and then coiled.
Various quality grades are produced to meet the varying needs of clients. With one of the most state-of- the-art technology in the world, SSI’s hot rolling mill can produce hot rolled steel sheet of 1.0 mm thick.
SSI’s production of hot-rolled steel sheet may be characterized as a stand-alone hot rolling mill of flat steel, comprising two sections:

Applications
The hot-rolled steel sheet in coils of SSI is used in numerous industries throughout Thailand, including the construction, steel pipe, gas cylinders, container, automobile, and auto parts industries,
and is also sent abroad. It is, furthermore, the main raw material in the production of cold-rolled steel sheet, which is in turn the raw material in the manufacture of automobiles, auto parts, electrical appliances, and coated steel sheet.
