The detailed TMT bars length and weight chart in this blog post will help you determine the total number of bars you will need for your specific building projects.

TMT bars are a necessary item in construction works. As some of you might know, TMT bars are required no matter if a home or an office property is being constructed. Once purchasing TMT bars, you would then select the bar depending on its radius. Whereas the TMT length is generally compatible, the radius can vary. TMT bars, generally speaking, are widely available in various diameters, including 32 mm, 20 mm, 16 mm, 12 mm, 10 mm, and 8 mm.

You must determine how much mass of TMT bars you necessitate based on the project specifications.

It is necessary to calculate the bar weight for which an equation exists. We have such a TMT bars length and weight chart for your simplicity. So, letâ€™s now discover all those related things about TMT bars’ weight and length.

## The Mass of Steel Bars

Steel bar weight, as some of you might know, is generally gauged in kilograms or tons, and it can also be measured in kilograms for each meter, lbs for every foot, or kilograms for every foot of various sizes of bars, for instance, 25 mm, 20 mm, 16 mm, 12 mm, 10 mm, 8mm, and a lot more. Steel bar furnished either in straight rod or U bent, with a length of approximately 40 feet (approx. 12 meters).

**Weight of steel bar**

The weight of a steel bar for every meter for a bar with a length of 8mm is approximately 0.395kg, for 20mm-bar it is approximately 2.47kg, for 16mm-bar it is 1.58kg, for a 12mm-bar it is 0.889kg, and for a 10mm-bar it is approximately 0.617kg.

**The mass of a 20mm rebar, rod, or steel bar** is approximately 2.47kg for every meter, 0.751kg for every foot, 29.63kg for every piece (12 meters full size), and 59.26kgs for every bundle.

**The mass of a 16mm rebar, rod, or steel bar** is approximately 1.58kg for every meter, 0.48kg for every foot, 18.96kg for every piece (12 meters full size), and 56.889kgs for every bundle.

**The mass of a 12mm rebar, rod, or steel bar** is approximately 0.89kg for every meter, 53.34kgs for every bundle, 10.66kg for every piece (12 meters full size), and 0.27kg for every foot.

**The mass of a 10mm rebar, rod, or steel bar** is approximately 0.617kg for every meter, 51.85kgs for every bundle, 7.407kg for every piece (12 meters full size), and 0.188kg for every foot.

**The mass of an 8mm rebar, rod, or steel bar** is approximately 0.395kg for every meter, 47.4kgs for every bundle, 4.74kg for every piece (12 meters full size), and 0.12kg for every foot.

**The equation for calculating steel bar weight:** D2L/162 is the method for determining the unit mass of steel bars in kilograms for every meter, in which 162 is a fixed number, L is considered the length of the steel in m., and D is the radius of the steel bars. The D2L/533 Formula is generally utilized to determine the total mass of a steel bar in kilograms for every foot.

Steel, as you might all know, is a load-bearing content that is commonly used in building project boundaries such as industrial construction projects, building services, bridge and reservoir structures, roof structures of residential and commercial buildings, apartment areas, and numerous other kinds of civil engineering work.

On the other hand, steel is employed in RCC structural components such as base footings, column beams, and roof slabs.

A lot of people would really want to know how much steel bar weight is necessary for home building. We start making an early indication and expense prior to actually commencing the project by understanding the weight of one sheet of steel, the length of a metal rod, the number of steel bars in a bundle, the weight of steel bars for every foot, and the weight of steel bars for every meter.

## How to Determine Steel TMT Rod Bundles Weight

Steel TMT bars are required for the building of contemporary residences in India. They provide the internal structure to building structures and aid in the prevention of collapse during seismic events. The Bureau of Indian Standards (commonly known as BIS) Standard IS-1786 specifies the maximum stiffness of malformed steel bars and cables for reinforcing materials. This benchmark is followed by all trusted brands when creating premium-quality TMT bars.

Once you opt to purchase TMT bars for the building projects of your home, your engineer or building engineer would then instruct you to purchase TMT bars in bundles. In addition, they will also clearly state the size of the TMT bar you need to purchase.

The amount of TMT bars in your package would be determined by the size of the TMT bars that you purchase. The distance of a basic TMT bar is usually 12 meters; the radius might vary considerably. A radius of 32 mm, 25 mm, 20 mm, 16 mm, 12 mm, 10 mm, or 8 mm is all available on the market.

The mass of the bars for each package must be coherent, with only minor alterations permitted. This variability is known as mass acceptance, and it must comply with IS:1786-2008 standard law. For various bar sizes, it is as follows.

## The Weight of TMT Bars Can be Calculated Using This Formula

TMT bars are purchased in bundles once purchased. TMT bar packages might typically be the same mass. To make sure mass continuity, the IS:1786-208 benchmark must be followed.

There is a method for determining the weight of steel in kgs per square meter.

The weight formula of TMT bars is D x D/162.

The radius of the TMT bar is denoted by D in this equation. Let’s look at how this equation is applied.

If you require TMT bars with an 8 mm diameter. The mass would be = 8 x 8 / 162 = 0.369 kg. As such, this is the weight for every sq meter for every bar.

If you need to calculate the mass, use the equation D x D x L / 162. D denotes the radius, and L denotes the length (normally 12).

Let us now compute the mass of a 10 mm TMT bar.

The mass W = 10 x 10 x 12 / 162 = 7.41.

As a result, the mass of a TMT bar will be 7.41 kg.

The IS standard allows for an acceptance of + or – 7%. This equation might also be used to determine the mass of a bar of any radius.

## The Bottom Line

Generally speaking, TMT bars often come in a full size of 12 meters (in terms of length). Having said that, as you might all know, the mass of these TMT bars varies depending on the diameter of the bar.

Accordingly, the bar with a diameter of 20 mm weighs around 2.47 kg, while the mass would be 1.58 kg for a bar of 16 mm, 0.889 kg for a bar of 12 mm, 0.617 kg for a bar of 10 mm, and 0,395 kg for a bar of 8 mm.
