8mm Steel Bar: Weight Per Meter and Calculation Guide

Bars made from steel are essential in the construction industry for providing additional support to concrete structures and increasing their overall durability. Among the different sizes available, the 8mm steel bar stands out for its versatility and frequent use in residential and light commercial construction. This article gives a general overview of the 8mm steel bar, its weight per meter, tips on calculations, pricing details, and other related information to help you plan your construction project.

What Is an 8mm Steel Bar?  

An 8mm steel bar refers to a round bar with an 8 millimetre diameter. It is a popular steel diameter used in building construction, like slabs, beams, columns, and in some cases, even as light reinforcements in small structures. Its strength, workability, and availability in most parts of the country make it a widely used steel. Because of its manageable weight and size, it's often preferred for smaller-scale or detailed work in construction.

8mm Rod Weight Per Meter   

One of the first things people search is the mass of an 8 mm rod for a meter length. This is useful for estimating how much material will be required, the costs, as well as for transportation arrangements. Although determining the weight involves some calculations, the approximate figure that is normally accepted is straightforward:

An 8mm steel bar in length meters will approximately weigh 0.395 kilograms  

Most people will utilise this value for quick on-site calculations. Whether a contractor, engineer or just a basic individual thinking of doing some construction, this figure aids in calculating the amount of steel required for the project. This figure, when multiplied by the total number of meters, gives the total approximate weight in kilograms.

8mm Steel Weight Per Meter  

Although ‘8mm rod weight per meter’ and ‘8mm steel weight per meter’ might seem different, they are, in reality, the same. The discrepancy lies only in the way people choose to phrase or refer to it. Either way, we are still talking about the same steel bar, which has a diameter of 8 millimetres and the weight per meter of roughly 0.395 kg.

This standard is applicable to builders, suppliers, and planners in all cases when managing orders and budget estimates. It helps maintain accuracy and uniformity in planning, irrespective of whether one 10 meters or 1000 meters is being worked on.

Weight of 8mm Steel Rod with Length of 40 Feet   

Steel rods are frequently supplied in feet, with 40 being one of the most common lengths. First, it’s important to convert feet to meters in order to get the weight of a rod. Now let's look at the calculations.

1 foot is 0.3048 meters

=> 40 feet equals 12.192 meters.
Simply multiplying the value from above by the standard weight per meter gives us:

Weight = 12.192 meters × 0.395 kg/m = approximately 4.81 kilograms

Thus, a 40-foot 8mm steel rod weighs around 4.81 kg. If you’re dealing with steel in lengths of 40 ft, keeping this number in mind can be useful. This figure streamlines weight and cost estimation for numerous rods that need to be ordered.

8mm Piece Steel Rod Weight   

Steel bars are normally offered for sale in predefined lengths, with a twelve-meter piece being the most frequently encountered. In the case of an 8mm rod, if you are buying one full-length piece, the weight can be calculated more easily.

1 piece = 12 meters
Weight = 12 × 0.395 kg = approximately 4.74 kilograms

Hence, the weight of a steel rod that is 12 meters in length is approximately 4.74 kg. This simplifies the requirement estimation for projects, as the rod’s weight is predetermined. For example, in the case that the rods needed are one hundred, then the total weight of steel would be approximately 474 kilograms. Estimations of this nature are, at times, employed by builders and contractors during the procurement and planning phases.

Price For TMT Bar Per Kg  

Knowing the rod’s weight alone is not sufficient; knowing its price, particularly for the TMT bars per kg, is equally important. The demand and supply for steel, along with the brand, quality and even the location, have a heavy impact on the steel’s pricing. Even though these factors have an impact, that doesn’t mean these estimates can’t assist you.
Current data suggests that the 8mm TMT bar price per kilogram is no lower than ₹58 and no more than ₹72 per kg.

All of these factors are bundled together and contribute to a price that includes the brand's quality, local taxes, delivery charges, other handling fees, etc. Because the price is not constant and changes often, you should check with your local supplier or dealer to confirm the current rates before buying in bulk.

Sometimes, a few builders might not get better rates, but they do if they’re buying in large quantities. There is, therefore, some order-size driven flexibility.

Using These Numbers in Real Projects

Knowing the price per kilogram and the weight per meter enables you to do some calculations. Let's say your project requires 500 meters of 8 mm bar:

500 × 0.395 = 197.5 kg

And with the current price being ₹65/kg, the cost would be:

197.5 × 65 = ₹12,837.50
This is a very simplified method for projecting the required steel and budgeted expenses. The same numbers are applicable if the bar is bought piece by piece.

• 1 piece = 4.74 kg
• 10 pieces = 47.4 kg
• 50 pieces = 237 kg

All you need to do is multiply the above figure by the price per kg to have an estimation of the material cost. These kinds of simple estimations help stay on schedule and on budget for the project in question.

Other Considerations   

Besides weighing the cost and the weight, there are additional factors to consider when selecting steel for construction. These include, but are not limited to, brand, TMT bar grade, certification, and storage and transport conditions. Typically, the first aspects people consider for preliminary estimates and material logistics are the primary cost and weight.
Knowing approximate values for 8mm steel bar weight and cost aids greatly in designing an effective construction strategy. This guidance is valuable for those working on single-family homes, small office constructions, or even just performing maintenance work, as it helps minimise excess material, deficit scenarios, and budget overruns.

Conclusion   

The 8mm steel bar is a construction piece that is both dependable and frequently used because of its strength and flexibility. 8mm rod or 8mm TMT bar, the attributes remain unaltered:

• Weight per meter: Approx 0.395 kg
• 40 ft rod weight: Approx 4.81 kg
• 1 piece (12m) rod weight: Approx 4.74 kg
• Price per kg: Usually ranges from ₹58 to ₹72

Using these figures, you can quickly estimate the material required for varying construction projects. While consulting with engineers and suppliers is always a good idea for precise planning, a rough understanding of these fundamentals can help make critical decisions without wasting time.
Purchasing a few rods for repairs or hundreds for a full project, these estimates ensure you are prepared to manage your materials and budget.
