What is Unit Weight of Steel Bars?

Weight of Steel Bars

Steel has been long use by humankind for various purposes, be it building homes, bridges, or dams. The industry of steel has revolutionized over the years. It is necessary to decide on the best one that serves your purpose the best. Be it steel bar grade, resistance properties, brands, certifications, flexibility, or malleability. A lot of factors are taken into account when selecting a steel bar, and quite often the weight of steel bar can get people confused. Choosing the right bundle can have quite an impact on your structure’s foundation.

Steel or rebar unit mass is calculated as the weight of the steel bar divided by its volume. The standard units of measurement are pounds per cubic foot (lb/ft3) or kilograms per cubic meter (kg/m3). Steel has a unit mass of 7850 kg/m3, which is equal to 490 lbs/ft3 (pounds per cubic foot).

Unit weight of steel

The ratio of the weight of the steel to the volume of the steel is known as the unit weight of steel. The unit weight of steel is often measured in kilograms per cubic meter (7850 kg/m3), kilograms per cubic centimeter (78.5 kN/m3), or grams per cubic centimeter (7.85 g/cm3), which is roughly equivalent to pounds per cubic foot (490 lbs/ft3) or pounds per cubic yard (13,231).

The unit steel bar weight is defined as the ratio of its mass to its volume, which is expressed in terms of kilograms and pounds and cubic meters and cubic feet, respectively (ft3).  Its unit weight is define as W = m/V. Where W stands for steel unit weights and m and V indicate mass and volume, respectively. Its SI unit is the kilogram per cubic meter (kg/m3) and it is sometimes refer to as the specific weight of steel or the density of steel. Knowing the steel unit weight makes it simple to determine how much steel is need for projects as steel is the most frequently utilize element in civil engineering for structural building.

The majority of the time, steel bars are employe as reinforcement to strengthen concrete structures. Structure steel is consider to weigh 7850 kg/m3, 78.5 kN/m3, 7.85 g/cm3, 490 lbs/ft3, or 13,231 lbs/yd3 per unit. 

The unit weight of steel bars can be calculate in different ways. And changes according to the units that are consider.

  1. Unit Weight in Kg/m³  of steel bars
  • It is the ratio of steel weight per unit volume.
  • Kg/m³ is its SI unit.
  • Steel weighs 7850 kg/m3 per unit.
  1. Unit Weight in Kg/m of steel bars
  • It is the proportion of steel weight to length.
  • Kg/m is its SI unit.

The unit weight of steel bars per meter

  • The unit weight for 6mm steel bars is about 0.222 kilogram per meter.
  • For an 8mm steel bar, it is 0.395 kg per meter.
  • For a 10mm steel bar, it is 0.617 kg per meter. 
  • For a 12mm steel bar, it is 0.89 kg per meter. 
  • For a 16mm steel bar, it is 1.58 kg per meter.
  • For a 20mm steel bar, it is 2.47 kg per meter.
  • For a 25mm steel bar, it is 3.86 kg per meter.
  • For a 32mm steel bar, it is 6.32 kg per meter.
  • For a 40mm steel bar, it is 9.87 kg per meter.

The unit weight per foot of steel bars

  • The unit weight of 6mm steel bars is approximately 0.067 kg per foot.
  • For an 8mm steel bar, it is 0.120 kg per foot.
  • For a 10mm steel bar, it is 0.188 kg per foot.
  • For a 12mm steel bar, it is 0.270 kg per foot.
  • For a 16mm steel bar, it is 0.480 kg per foot.
  • For a 20mm steel bar, it is 0.751 kg per foot.
  • For a 25mm steel bar, it is 1.174 kg per foot.
  • For a 32mm steel bar, it is 1.925 kg per foot.

Steel unit weight:- If the weight of the reinforcing bar or rebar is measured in pounds per foot, it is known as the unit weight of rebar in lb/ft. Steel unit weight is stat as mass per unit length.

The unit weight of steel bars in pounds per foot

The unit weight of #2 steel bars is 0.265 pounds per foot. 

The #3 steel bar is 0.376 pounds per foot

The #4 steel bar is 0.668 pounds per foot.

The #5 steel bar is 1.043 pounds per foot.

The #6 steel bar is 1.502 pounds per foot.

The #7 steel bar is 2.044 pounds per foot.

The #8 steel bar is 2.67 pounds per foot.

The #9 steel bar is 3.40 pounds per foot.

The #10 steel bar is 4.303 pounds per foot.

The #11 steel bar is 5.313 pounds per foot.

A steel’s internal structure and composition may alter to customize its qualities, which accounts for its versatility. Razor blade strips, paperclips, bridges, massive beams for columns, and skyscrapers. For many years, steel has been the main material utilize in construction projects. The long-term performance of steel structures is stable, and they don’t expand or contract in accordance with moisture content.  or distort. Steel is isotropic, meaning that its dimensional properties are the same in all directions.
