These bars having the yield strength of 600 N/mm2 have the highest strength obtainable in that category. They are typically used in structures that need high tensile and yield strength. The steel bars are used for large scale industrial building projects. Strengthening Measurement will be reduced by approx. 8% when we use Fe 600 by looking at the configuration of the building's structure. If the strengthening factor is 7.5 kg per sq.ft then the reduction will be 0.6 kg per sq.ft. Fe600 is Good for earthquake areas because of its high strength.
