LEADERSHIP THROUGH EXCELLENCE IN QUALITY AND COMMITMENT SENTHIL GROUP OF COMPANIES is a conglomerate with its head quarters in Coimbatore. We are into Mining, Bio-Tech, Paper & Boards, Energy, Cement Products, Infra Structure, Food Products, Packaging, Entertainment, Education and charities. Now we have added a New feather to our Cap in the form of SENTHIL STEEL COMPANY PVT LTD. This New entity adds to the various divisions already in Senthil Groups and currently occupies a place among the leading high end manufacturers and suppliers of quality steel bars with ISI certi cation such as IS 1786. The Group's bench mark for endurance, commitment and quest for continued excellence is adapted for this division also.
CONFORMING TO NATIONAL AND INTERNATIONAL STANDARDS SS-TMT bars con rm to most national standards and codes of Practice. SS-TMT con rms to IS – 1786 CM/L – 6254970 of Indian standards. It satis es the corresponding French and other European standards.
TECHNICALLY SUPERIOR PRODUCT SS TMTcon rms to technology leadership among other Manufacturers by adapting to TEMPCORE TMT process technology.
TMT MANUFACTURING PROCESS In order to maintain a consistent raw material base, we at SS-TMT manufacture our own sponge Iron used in manufacture. The pellets are further processed in our own smelting plants to produce ingots. TMT process can be described in three successive stages. The rst stage is when the hot rolled bar is rapidly quenched by special water spraying system. Consequent to this initial stage, in the second stage where-in temperature gradiance in formed meaning the surface temperature is less than that of the core. This results in the temperature of the core automatically getting transferred to the surface resulting in formation of Tempered Martensite which is strong and tough. Finally the rods are left for atmospheric cooling where-in the core transforms itself into soft Ductile inner core called ferrite, pearlite and strong outer layer called Martensite. SS-TMT is a perfect blend of these strength and ductile parameters.
