# How Does The Weight Of The Various Specifications

May 22, 2018

0.617 is round 10 rebar weight per meter.The weight of the bar is proportional to the square of the diameter (radius).

G/m = 0.617 * * D / 100 D

The weight of each meter (Kg) = the diameter of the steel bar (mm) x steel diameter (mm) x 0.00617.

Actually remember construction commonly used steel weight is simple from 6 = 0.222 Kg 6.5 = 0.26 Kg = 0.395 Kg phi phi 8 10 = 0.617 Kg phi 12 14 = 1.21 Kg = 0.888 Kg Φ Φ 16 = 1.58 Kg Φ 18 24 = 2.47 Kg = 2.0 Kg Φ Φ 22 = 2.98 Kg Φ 25 = 3.85 Kg Φ 28 = 3.85 Kg...

Φ under twelve (12) and Φ 28 (28) reinforced generally take three digits after the decimal point, Φ 14 to 25 reinforced Φ generally take 2 decimal places

Φ 6 = 0.222 Kg

Φ 8 = 0.395 Kg

Φ 10 = 0.617 Kg

Φ 12 = 0.888 Kg

Φ 14 = 1.21 Kg

Φ 16 = 1.58 Kg

Φ 18 = 2 kg

Φ 20 = 2.47 Kg

Φ 22 = 3 kg

Φ 25 = 3.86 Kg

Φ 28 = 4.83 Kg

Φ 32 = 6.31 Kg

Φ 36 = 7.99 Kg

Φ 40 = 9.87 Kg

The theoretical weight of steel is simplified.

Flat steel, steel plate, steel belt W = 0.00785 x width x thickness.

Square steel W = 0.00785 x side length 2.

Round steel, wire, wire W = 0.00617 x diameter 2.

Steel tube W = 0.02466 x wall thickness (outer diameter - wall thickness)

Equilateral Angle steel W = 0.00785 x edge thickness (2 edge width -- side thickness)

Unequilateral Angle steel W = 0.00785 x edge thickness (long edge width + short edge width - edge thickness)

W = 0.00785 * waist thick [high +f (leg wide - waist thick)]

Channel steel W = 0.00785 * waist thick [high +e (leg wide - waist thick)]
