Abstract: General Steel Structures are designed using standard steel sections. The design is governed by the Code IS 800-2007, and the standard steel sections are chosen from SP: 6(1)-1964.The standard steel sections regularly used in construction are, I, Channel, Tee and Angle (Equal & Unequal) sections, i.e., overall 252 sections. SP: 6(1)-1964 gives the sectional properties of all these 252 standard sections, including the cross sectional areas, for the use of designers, to select the most stable and economical section to satisfy the loading conditions of the structure. An economical section is one which has the least cross sectional area and hence, least weight. In SP: 6(1)-1964, the cross sectional areas are given in cm2 to an accuracy of two decimal places. In this paper, the accuracy of the areas of all these sections, except ISHB sections (all IS Heavy Beams) and ISWB 600 @ 145.1 kg/m, i.e., totally 234 sections, are verified in mm2 to an accuracy of two decimal places. The results show differences in values of areas for eight Tee-sections only, which have been tabulated. Cross sectional areas of all other 226 sections perfectly match with the values given in SP: 6(1)-1964.
