MS Round Bars are solid, cylindrical rods manufactured from a combination of low-carbon steel. They are popular in the industry for their strength, ductility, and versatility. From construction, automotive, fabrication, and engineering to machinery, they are used as core components in manufacturing processes across a wide range of industries.
However, when procuring mild steel round bars, industries should have a clear concept of the process they plan to use these bars in. They are widely used for fabrication, structural construction and construction processes. Industries need to ask the supplier the right questions to understand the size, tolerance levels, and available brands before sourcing bulk MS round bars for processing.
What diameters are available for MS Bar, and how do the heights vary?
The diameter of the MS Round Bar directly affects the weight, robustness, and suitability for industrial applications. For instance, projects following specifications like IS 2062 or EN8/EN have strict diameter and tolerance requirements for the use of MS round bars.
Hence, before ordering bulk amounts of mild steel round bars, industries enquire with the supplier about the available sizes or diameters. The available standard size is 5 mm to 110 mm. This helps them back-calculate the tonnage and cost for the MS bars.
For instance, suppliers will provide details of the MS bar size chart as follows.
| MS ROUND BAR WEIGHT CHART | |||||
|---|---|---|---|---|---|
| Item | Size (in mm) | Weight Per Meter In KG | Weight Per Foot in KG | Weight Per 6 Meter Pcs | Approximate Pieces In 1 Ton (Single Piece Length 6 Meter) |
| Round Bar | 10mm | 0.617 | 0.19 | 3.70 | 270 |
| Round Bar | 12mm | 0.888 | 0.27 | 5.33 | 188 |
| Round Bar | 16mm | 1.58 | 0.48 | 9.48 | 105 |
| Round Bar | 20mm | 3.14 | 0.96 | 18.84 | 53 |
| Round Bar | 22mm | 2.98 | 0.91 | 17.88 | 56 |
| Round Bar | 25mm | 3.85 | 1.17 | 23.10 | 43 |
| Round Bar | 28mm | 4.83 | 1.47 | 28.98 | 35 |
| Round Bar | 32mm | 6.31 | 1.92 | 37.86 | 26 |
What questions should you ask the supplier about the size of MS Round Bars?
Here is a list of important facts that industries need to ask suppliers.
- What diameter (mm) options do you have in stock for the MS Round Bars?
- What is the weight per metre or per piece for each diameter that you’re offering?
- How many pieces are in a tonne for the available lengths you’re offering?
- What is the price per tonne, per bundle or per piece?
What information should you get about the length and tolerance of the bars?
Confirming the length and tolerance of MS bars is as essential as checking the size. These two parameters directly influence how effectively the industries can use the materials for different applications.
Why is it important?
Helps in accurate material planning
The standard lengths of MS round bars are generally within 5.5 to 6.5 meters, where the random length is 16 ft – 24 ft. Customised/Fixed Length Round is available from 3 meters to 12 meters. If the bars are shorter or longer than the standard length, then it can be difficult to cut and shape them for applications. This also leads to material wastage. Hence, industries must verify the exact length from the supplier to meet their requirements for effective utilisation.
Help in controlling costs
Mild steel round bars are generally sold by weight. The tolerance levels for length and weight affect the total weight of the bars. Even a slight variation of 0.5% can add or reduce significant costs to bulk orders. Hence, to keep material costs under control, it is essential to verify the length before making the purchase decision.
Helps in fabrication precision
Precision in fabrication is key to success in industries such as automation, construction, and manufacturing. Even a small deviation in the length tolerance can cause misalignments in frames and machine parts, reducing the functionality of the components. Thus, industries need to obtain specifications on the length from suppliers.
Here’s an example chart on size tolerance (diameter variation).
| For up to 25 mm diameter | ±0.5 mm |
| For 25mm–35mm | ±0.6 mm |
| For 35mm–50mm | ±0.8 mm |
| For 50mm–80mm | ±1.0 mm |
| For 80mm–100mm | ±1.3 mm |
| 100mm | ±1.6 mm |
What to ask the supplier about the length and tolerance?
Industries looking to make a bulk purchase of MS round bars should definitely enquire about the following information from suppliers.
- What is the standard length of the bars available?
- Are you offering customised lengths for the MS round bars?
- What is the tolerance on the length?
- What is the tolerance on weight per piece or per metre?
- What is the diameter tolerance for each size band that you supply?
Reputed suppliers will adhere to strict tolerances for length and diameter and comply with the IS 2062 standards. Thus, verifying these details with suppliers before procuring raw materials helps industries deliver precise engineering solutions.
