The combination of IS 2062 and IS 808 governs the manufacturing, strength, and dimensional standards for Mild Steel Bars used in structural, mechanical, and general fabrication works.
IS 2062:2011 specifies chemical composition, yield strength, tensile strength, and elongation properties for hot-rolled steel including plates, bars, and sections. It ensures consistency in strength and weldability for load-bearing applications.
IS 808:1989 defines the dimensions and theoretical weights of hot-rolled steel sections such as rounds, squares, angles, channels, and beams. These dimensions help in precise design calculations and cost estimation.
Theoretical weights are derived using the density of steel = 7.85 g/cm³. Actual weight may slightly vary depending on manufacturing tolerances as per BIS.
For Round Bars: Weight (kg) = (D² × 0.006165) × Length
For Square Bars: Weight (kg) = (A² × 0.00785) × Length
Example:
For a 20 mm round bar, 6 m long → Weight = (20² × 0.006165) × 6 = 14.8 kg
For a 25 mm square bar, 6 m long → Weight = (25² × 0.00785) × 6 = 29.4 kg
