CALCULATORS
Plan Smarter with RMS Calculators
Quick, accurate, and free-to-use tools for rebar, mesh, and masonry estimation.
At RMS, we know that time and accuracy matter on every project. Our free online calculators are designed specifically for South African engineers, contractors, and quantity surveyors. Whether you need a Concrete Slab estimate, a Rebar bending schedule, a Welded Mesh quantity, or Brick Force for masonry walls, our tools give you reliable results in seconds.
Our calculators are SANS-compliant, tested against industry standards, and built to help reduce material wastage whilst improving project efficiency.
Rebar Calculator
Calculate the total weight of your reinforcing bar order for both Y bar (high tensile) and R bar (mild steel) — by bar size, length, and quantity.
Advanced Rebar Calculator
Build a complete bending schedule with multiple elements, calculate your project grand total weight, and export a professional PDF.
Mesh Calculator
Estimate welded mesh requirements for slabs, pavements, and precast elements. Input dimensions and mesh type to get instant results.
Brick Force Calculator
Work out how much Brick Force your masonry walls need in linear metres and full rolls, based on wall length, height, and placement frequency.
Concrete Slab Estimator
Estimate concrete volume, reinforcing mesh sheets, and spacers for your slab based on dimensions and thickness. Covers residential through to industrial.
Simple Rebar Calculator
Work out the total weight of your reinforcing bar order based on bar size, length, and quantity.
Please note: This tool gives an estimated weight only. Actual quantities may vary depending on how bars are cut, lapped, and fabricated on site. Confirm your final rebar schedule against your structural drawings before ordering. RMS accepts no liability for orders placed on the basis of this estimate.
Advanced Rebar Calculator
Add elements to your rebar schedule one at a time, build your full project total, and export to PDF.
Please note: This tool gives an estimated weight only. Actual quantities may vary depending on how bars are cut, lapped, and fabricated on site. Confirm your final rebar schedule against your structural drawings before ordering. RMS accepts no liability for orders placed on the basis of this estimate.
Mesh Calculator
Work out how many mesh sheets and rolls your project needs, from an area or a sheet count.
Please note: These figures are a guide only. Sheet counts are rounded up to whole sheets since partial sheets cannot be ordered. Confirm quantities against your project drawings before ordering. RMS accepts no liability for orders placed on the basis of this estimate.
Brick Force Calculator
Work out how much Brick Force your walls need, in linear metres and full rolls.
Please note: These figures are a guide only. They assume a standard 85 mm brick course including mortar, and add 10 percent for overlaps and offcuts. Confirm quantities against your engineer's specifications before placing an order. RMS accepts no liability for orders based on this estimate.
Concrete Slab Estimator
Work out the concrete volume, reinforcing mesh, and spacers your slab needs.
Please note: These figures are a guide only. The mesh allowance adds 10 percent for overlaps and offcuts. The concrete figure is the slab volume only and does not allow for subgrade unevenness or spillage on site. Confirm quantities against your engineer's specifications before placing an order. RMS accepts no liability for orders based on this estimate.
