Frequently Asked Questions
What is the formula for steel rod weight calculation?
The standard formula is W = D² ÷ 162, where W is weight in kg per metre and D is diameter in millimetres. This formula is used internationally and is the basis for ASTM, IS 1786, and BD BNBC standards for deformed mild steel bars.
How much does a 12mm rod weigh per metre in Bangladesh?
A 12mm MS deformed bar weighs 0.889 kg per metre (12² ÷ 162 = 0.889). A standard 12-metre rod therefore weighs approximately 10.67 kg. At ৳100/kg market price (2024-25), one 12-metre rod costs about ৳1,067.
What is the current price of MS rod per kg in Bangladesh?
As of 2024-25, MS deformed bar (Grade 60/BSTI-approved) in Bangladesh costs approximately ৳95–110 per kg depending on brand (BSRM, AKS, KSRM, Abul Khair), location, and market conditions. Steel prices fluctuate — always check your supplier for the current rate and enter it in the calculator.
Which rod diameter is most commonly used in Bangladesh?
12mm rods are the most common for slabs, beams and secondary columns. 16mm and 20mm are used for main column reinforcement. 8mm rods are used for stirrups and links. 10mm is used for light structural members and secondary bars.
What is the standard length of an MS rod in Bangladesh?
Standard mill-cut length is 12 metres. However, rods are also available in 6-metre lengths and custom cut lengths from steel yards. Enter your actual cut length for accurate weight and cost calculations.
