How calculate weight of the steel bar? How many steel rods in a bundle?

Steel using in construction work

Steel is an alloy of iron and carbon material. It is improving strength in construction of building and engineering works. 

What are the types of steel bars used in construction work?

Mostly there are 6 types of steel bars are using for construction work.

1.     8mm bar

2.     10mm bar

3.     12mm bar

4.     16mm bar

5.     20mm bar

6.     25mm bar

Mostly 8mm bar using for stirrups or ties in column and beams. Also 10mm bars are using in column and beam stirrups or ties.

NOTE: MINIMUM 12mm DIA OF BAR SHOULD BE USE IN COLUMNS

 

12mm bars and more than 12mm bars are using in main rod of column and beam.

How many steel rods in a bundle?

8mm rod bundle    = 10 No`s

10mm rod bundle  = 7 No`s

12mm rod bundle  = 5 No`s

16mm rod bundle  = 3 No`s

20mm rode bundle = 2 No`s

25mm rod bundle  = 1 No`s

How calculate weight of the steel bar?

We are using basic formula to find out the weight of steel bar in meters.

W = D²L/ 162

Where,

            D = diameter of the steel bar in millimeter

            L = length of the steel bar in meter

The weight of steel bar will be varying depend on the density of steel and its brand.

Example:

For 1m weight of 8mm steel bar

Weight of 8mm steel bar = ((8x8) x 1)/ 162 = 0.39 kg/m

For 12m steel bar weight = 0.39 x 12 = 4.74kg.

 

NOTE: We know a formula to calculate the weight of steel bar W = D2.L/162. For feet to calculate the weight of reinforcement is W = D2/533 (Just convert meter into feet) We know the unit weight of steel rod is 7850 kg/m3

 

 

 

 

 

Weight of reinforcement for 1 meter bar

Ø 8mm bar     = W = D²L/ 162 = ((8x8) x 1)/ 162               = 0.395kg/m

Ø 10mm bar  = W = D²L/ 162 = ((10x10) x 1)/ 162          = 0.617kg/m

Ø 12mm bar  = W = D²L/ 162 = ((12x12) x 1)/ 162          = 0.888kg/m

Ø 16mm bar  = W = D²L/ 162 = ((16x16) x 1)/ 162          = 1.580kg/m

Ø 20mm bar  = W = D²L/ 162 = ((20x20) x 1)/ 162          = 2.469kg/m

Ø 25mm bar  = W = D²L/ 162 = ((25x25) x 1)/ 162          = 3.858kg/m

 

Weight of reinforcement for 1 feet bar

Ø 8mm bar     = W = D²L/ 533 = ((8x8) x 1)/ 533               = 0.120kg/m

Ø 10mm bar  = W = D²L/ 533 = ((10x10) x 1)/ 533          = 0.188kg/m

Ø 12mm bar  = W = D²L/ 533 = ((12x12) x 1)/ 533          = 0.270kg/m

Ø 16mm bar  = W = D²L/ 533 = ((16x16) x 1)/ 533          = 0.480kg/m

Ø 20mm bar  = W = D²L/ 533 = ((20x20) x 1)/ 533          = 0.750kg/m

Ø 25mm bar  = W = D²L/ 533 = ((25x25) x 1)/ 533          = 1.172kg/m

 

What is the standard length of the steel bar?

We are using reinforcement for structural members. Its total length of the reinforcement is 12m. In a bundle each rod has 12m length. Some where the reinforcement length is 39 feet to 41 feet.

 

How convert weight from grams to Weight In KG, Pounds, MilliGram, US Ton, stones, Ounces?

Weight Converter

Type a value in the Grams field to convert the value :

Grams

Kilograms:

Milligrams:

Pounds:

Ounces:

Stones:

US ton:

Formula

Convert from Grams to KG = x / 1000 (or ) x * 0.001

Convert from Grams to pounds = x * 0.00220462

Convert from Grams to milligrams = x * 1000

Convert from Grams to US Ton = x * 1.1023e-6

Convert from Grams to ounce (oz) = x * 0.035274

Convert from Grams to stones (oz) = x *0.00015747

NOTE: where, (x) = Grams value

Example

We take 520 grams to convert to Kg = 520 x 0.001 = 0.52 Kg
