Reinforcement Steel Calculator | NexUtils
Steel Weight Calculator
Calculate TMT bar weight using D²/162 formula.
Enter diameter & length
About This Tool
Steel reinforcement is the backbone of any RCC (Reinforced Cement Concrete) structure. The Reinforcement Calculator helps site engineers and contractors estimate the quantity of TMT bars required for different structural elements like Footings, Columns, Beams, and Slabs. Unlike simple weight calculators, this tool considers the structural design—number of main bars, distribution bars, and stirrups (rings)—to give you a detailed Bar Bending Schedule (BBS). It calculates the total cutting length, including hooks and bends, and converts it into standard commercial weight. This tool has become indispensable for construction professionals across India, from small contractors to large construction firms. It accounts for industry-standard specifications and local building codes, ensuring your estimates are accurate and reliable. The calculator helps prevent costly mistakes like material shortages mid-project or excessive wastage that impacts your budget. Whether you're bidding on a project, planning a renovation, or managing a large construction site, this tool provides the precision you need for successful project execution. It saves hours of manual calculations and reduces the risk of human error in critical construction planning. Our algorithms are optimized for performance, ensuring instant results even for complex calculations. We are committed to providing free, high-quality tools to help you be more productive.
How to Use This Tool
Select Element
Choose Slab, Beam, or Column.
Input Dimensions
Enter Length, Width, and Depth of the member.
Bar Details
Specify bar diameter and spacing (dist. c/c).
Calculate
Get total length and weight of steel required.
Key Features
- BBS Generation: Creates a basic Bar Bending Schedule.
- Structural Elements: Templates for Slabs, Beams, Columns, and Footings.
- Hook Allowance: Adds standard hook lengths (9d, 10d) automatically.
- Overlap Logic: Accounts for lapping length (45d/50d) in long spans.
- Stirrup Calculation: Estimates rings required based on spacing.
Frequently Asked Questions
What is the standard overlap length?
The standard overlap (lapping) for reinforcement is usually 45 to 50 times the diameter of the bar (45d-50d) depending on the grade of concrete and steel.
How is hook length calculated?
For 90° bends, add 2d. For 135° hooks (stirrups), add 10d or 12d per hook.
