Dimension-Based Weight Verification for Metal Sheets and Rods with Inveck
Measure the Size. Get the Weight. Skip the Scale.
A metals company in India, holding plates, sheets and rods, verifies stock by entering dimensions in the Inveck app. The system calculates each item's weight from its density and reports variances in kilograms directly — no weighbridge, no manual calculation.
These numbers don’t happen by chance. See how it was done
Who is the client?
The client stocks and processes metal sheets, plates and round bars in India for fabrication, engineering and construction customers. Its yards and warehouses hold material in many grades — mild steel, stainless steel, aluminium and alloy steels — and in many sizes, including cut pieces and offcuts.
The ERP carries all of this stock in kilograms. Physically, it lies on the floor as heavy plates in stacks and bundles of rods, where every piece has a different size and putting each one on a scale is not practical.
Book a DemoChallenges that held them back
The books were in kilograms, but the floor could only be counted in pieces and sizes. Bridging the two was slow, costly and error-prone.
Weighing everything was impossible
Plates weighing hundreds of kilograms and long rod bundles needed cranes and weighbridges. Weighing each piece would have stopped operations for days.
Manual weight calculations
Auditors measured pieces, then worked out weight by hand or in Excel using density tables. Different people used different formulas and rounding.
Unit mix-ups
Dimensions in millimetres, metres and inches, and densities in g/cm³ or kg/m³, produced errors of ten or a thousand times.
Variances in pieces, books in kg
Count sheets showed pieces and sizes; the ERP showed kilograms. Reconciliation needed a separate conversion exercise.
Offcuts and cut pieces ignored
Odd-sized pieces were hard to value, so they were estimated or left out.
Slow, disputed results
Weight figures built by hand were questioned by finance and auditors, and the full reconciliation took three weeks.
How Inveck solved it
Inveck lets auditors count what they can measure and leaves the weight to the system. For a sheet or plate, the auditor enters length, breadth and thickness (height). For a rod, length and radius. Each item carries its density factor, so Inveck calculates the weight of every piece and compares it with book stock in kilograms.
Book stock in kilograms was uploaded as a milestone. Each item was tagged with its shape (sheet or rod) and its density factor by grade — for example, mild steel, stainless steel or aluminium. The count screen was configured to show the right dimension fields for each shape, in fixed units, so auditors only measure and type. Auditors download the milestone, count offline in the yard, and sync when back online.
Shape-specific inputs
Sheets ask for length, breadth and thickness; rods ask for length and radius.
Density factor per item
Each grade's density is set once at setup, so every auditor uses the same value.
Automatic weight calculation
The system converts dimensions to weight — no calculators, tables or Excel.
Fixed units
Dimension units are set on the input fields, removing mm, m and inch mix-ups.
Piece-by-piece entries
Every plate, rod or offcut is its own entry, so odd sizes are counted, not estimated.
Variance in kg
Calculated weight is compared with ERP stock and shown as excess or shortage in kilograms.
Offline counting
Milestone data stays on the device for open yards and sheds with poor network.
Pending and variance review
Review Pending and Review Excess/Short ensure nothing is missed before closure.
Digital sign-off and audit trail
Every entry carries its dimensions, user and timestamp; the Incharge signs on the device.
How It Works on the Floor
The auditor's job ends at the measuring tape; weight and variance come from the system.
Dimension-to-variance flow · sheets and rods
Because density is set per item at setup, a stainless plate and a mild steel plate of the same size get their correct, different weights automatically.
The Calculation, with a Worked Example
Inveck works out volume from the shape's dimensions and multiplies it by the item's density.
Sheets and plates
W_{\text{sheet}} = L \times B \times T \times \rho
Rods and round bars
W_{\text{rod}} = \pi \times r^{2} \times L \times \rho
Where W is weight, L length, B breadth, T thickness (height), r radius and ρ the item's density.
Worked example for mild steel, density 7,850 kg/m³ (illustrative figures):
| Item | Auditor enters | Volume per piece | Weight per piece | Pieces counted | Counted weight | Book stock | Variance |
|---|---|---|---|---|---|---|---|
| MS plate | L 2,500 mm · B 1,250 mm · T 10 mm | 0.03125 m³ | 245.31 kg | 20 | 4,906.25 kg | 5,000.00 kg | −93.75 kg |
| MS round bar | L 6,000 mm · r 10 mm | 0.0018850 m³ | 14.80 kg | 150 | 2,219.54 kg | 2,150.00 kg | +69.54 kg |
The auditor typed only dimensions and piece counts. Every weight and variance above is calculated by the system.
The results
The client now verifies heavy metal stock in kilograms without lifting a single piece onto a scale.
No weighing during verification
Cranes and weighbridges stay on production work; auditors only need a measuring tape and the app.
No manual calculations
Weight is worked out by the system from dimensions and density, the same way for every auditor and every piece.
Variance straight in kilograms
Physical stock is compared with ERP stock in the same unit, so excess and shortage are ready to post.
Unit and formula errors eliminated
Fixed units and preset densities remove the conversion mistakes that used to create false variances.
Offcuts counted properly
Every cut piece and odd size gets its own measured entry and calculated weight.
Faster close
Verification and reconciliation that took three weeks now close in four days, with results finance and auditors accept.
Full audit trail
Each weight can be traced back to the measured dimensions, the density used, who measured it and when.
Weighing every plate and bar during a stock count was never realistic, and calculating weights by hand led to endless arguments over the numbers. With Inveck, our team just measures and enters the size; the system does the rest and gives us the variance in kilograms against our books. Verification is faster, and nobody questions the figures any more.
