What is steel ?
Steel is an iron alloy that frequently also contains other metals and has a carbon percentage of between 0.03% and 1.075%. It has a great tensile strength and is affordable, making it a popular material for making tools, ships, automobiles, machineries, appliances, and even weapons. With annual production reaching 1.3 billion tonnes, it is one of the most well-known materials in the world. Today, we'll talk about the steel that's commonly used in reinforced cement concrete (R.C.C) projects.
What Is Unit Weight Of Steel Bars ?
Unit weight of steel is 7850 kg/m³.
It is the proportion of steel weight to volume. kg/m3 is its SI unit.
The primary usage of the steel bars is as reinforcement to increase the tensile strength of concrete structures. The weight of steel is typically expressed in kilogrammes, tonnes, and pounds.
Also, steel ranges in density from 7850 kg/m3 to 8050 kg/m3, depending on the grade and method of production.
However, the steel unit weight of 78.5 kN/m3 with a density of 7850 kg/m3 is widely used.
How To Calculate Unit Weight Of Steel Bars Formula ?
The formula used to get the unit weight of steel bars is D2/162. where D = diameter of steel bars, and 162 is a constant value derived by the derivation below .
Derivation Of The D2/162 Formula ?
steel bar weight = Volume of steel bar × Density of steel bar
steel bar weight = (Cross-sectional Area of bar × Length) × Density of steel bar
Unit weight of steel bar = ( πd²/4 x 1) x 7850
= ( πd²/4 X 1000) X 7850/1000000
= d²/162 kg/m
1m length= 1000mm length
How To Calculate The Unit Weight Of Steel Bars, For Example.
Unit weight of steel bars for 8 mm diameter = 8² / 162
= 0.395 kg/m
Unit weight of steel bars for 10 mm diameter = 10² / 162
= 0.617 kg/m
Unit weight of steel bars for 12 mm diameter = 12² / 162
= 0.888 kg/m
Unit weight of steel rebars for 16 mm diameter = 16² / 162
= 1.58 kg/m
Unit weight of steel rod for 20 mm diameter = 20² / 162
= 2.469 kg/m
Unit weight of steel rod for 25 mm diameter = 25² / 162
= 3.858 kg/m
Unit weight of steel rod for 32 mm diameter = 32² / 162
= 6.32 kg/m
Unit weight of steel rod for 40 mm diameter = 40² / 162
= 9.876 kg/m
