Accurate calculation of steel weight is crucial in many construction applications. It ensures structural integrity and safety, preventing overloading and potential failures. Using the correct weight formula helps avoid errors that can occur during physical measurements, reducing risks and improving efficiency in project planning. Table of contents The following tables provide precise weight values for various steel products used in construction and engineering projects. Steel Bar Weight Chart Weight Chart of Bars per Bundle Steel Plate Weight Chart Weight of Steel Bars Formula Steel Bars Weight = D² / 162 Where, D² / 162 Formula Derivation Weight of Steel Bar (W) = Unit Weight of Steel Bar (γ) x Volume (V) W = γ x V 7850 kg/m³ (γ) = Steel unit weight W = πD² / 4 x 7850 Steel diameter in mm will be converted to m to create a constant value in the same unit D² mm / 1000² The following table provides the weight of steel per meter, which is useful for different construction applications.

Check the formula to calculate weight of steel
D = Diameter
162 is a constant value
Consider,
Diameter = D
Length = L
W = πD² / 4 x γ (V = πD² / 4)
steel dia in mm
density = kg/m³
W = π / 4 x D² / 1000² x 7850
W = D² / 162.28 kg/m
W = D² / 162 kg/mRefer unit weight of steel per kg

Calculate the weight of steel pipes using below formula
D = steel pipe OD in mm
L = steel pipe length in m
Consider,
steel pipe OD (D)= 100 mm, length (L) = 6m
W = 0.02466 x 100^2 x 6 / 10202
W = 0.02466 x 10000 x 6 / 10202
W = 1480 / 10202
W = 0.145 kg/m
