Strength of the bars are carefully controlled by optimizing the water pressure for their pearlitic core and tough surface of tempered marten site, thereby providing an optimum strength, ductility and toughness. TMT bars are widely used in general purpose concrete reinforcement structures, bridges and flyovers, dams, thermal and hydel power plants, industrial structures, high-rise buildings, underground platforms in metro railway and rapid transport system. TMT Bars are thermo-mechanically-treated through leading world tempcore based technology for high yield strength. The process involves rapid quenching of the hot bars through a series of water jets after they roll out of the last mill stand. The bars are cooled, allowing the core and surface temperatures to equalize. The bar core cools down slowly to turn into a ferrlite-pearlite aggregate. Features of TMT Bars: Enhanced strength combined with high ductility Excellent weld ability without loss of strength at welded joints Better ductility and malleability Earthquake resistant High thermal resistance

GP/GC coils have excellent corrosion resistance, print-ability and workability. The De-greasing Section helps the removal of oil and dirt by a cascaded process of hot alkaline de-greasing, cold rising, hot rising and hot air drying. Then annealing is done in an electrically heated horizontal furnace operated under a protective atmosphere with a calibrated ratio of nitrogen and hydrogen generated in a state–of–the–art automated Protective Gas Plant using ammonia and air as primary raw materials. Immersing it in a zinc bath maintained at 460 degree centigrade carries out hot dip galvanizing of the strip. The chemistry of the bath is carefully controlled to ensure proper adhesion and formability of the applied zinc together with bright blemish free uniform spangles.The galvanized coils are chromated to improve its resistance to white rust. The chromating parameters are continually monitored and sheets are regularly tested through salt-spray tests to ensure the performance of this process. We can also provide galvanized plain and corrugated sheets with required length. Galvanized corrugated sheet can be produced with closed tolerance of standard depth, pitch and width.

Galvalume is a coated steel product that has proven its superior performance as a building material in extended field-testing in a diverse range of corrosive environments. Its unique combination of durability, edge protection, and resistance to corrosion is at least twice that of galvanized steel. The galvalume coating is an alloy composed of 55% aluminium, approximately 43.4% zinc by weight, and 1.6% of Silicon. It is applied on both sides of cold-rolled steel sheet using a precise continuous hot dip process. The result is highly corrosion resistant coated steel that combines the barrier protection and extended durability of aluminium with the galvanic protection of zinc.
