⚖️ Metal processing ERP · Weight-based costing
Weights from the weighbridge and scales, costs from purchases, power meters and payroll, all brought together per tonne. See yield loss and scrap credit, compare theoretical with actual weight, and price per kg, piece or metre with the margin in view.
Move the sliders. The waterfall shows how material, yield loss, conversion and scrap credit add up to the cost of one good tonne, and the margin at your selling price. Example values.
Choose a section, length and pieces. The ERP works out theoretical weight from kg per metre and compares it with the weighed bundle. Variance outside your tolerance is flagged.

Each process step adds conversion cost on top of the melt. Hover a step to see what it adds. Example cost per tonne.
One cost per tonne converts to price per kg, per piece or per metre. Pick a mode to see the conversion for a 12 m TMT 12 mm bar.

Cost per tonne draws on heats, scrap, shop floor and quality.
Answers for owners, finance heads and plant managers.
It works out cost per tonne or per kg, because metal is bought, processed and often sold by weight. Material, power, labour, consumables and overheads are spread over the good output weight, after yield loss and scrap credit.
Cost per tonne = (raw material cost ÷ yield) + conversion costs per tonne − scrap credit per tonne. The ERP collects each part from purchases, energy meters, payroll and production records.
Theoretical weight comes from the size and density, such as kg per metre from a section table. Actual weight is what the scale shows. Rolling tolerance means they differ, and the ERP tracks the variance on every bundle.
If yield falls from 96% to 94%, every good tonne needs more raw material. Since raw material is often the biggest cost, small yield changes move cost per tonne a lot.
Yes. The ERP converts cost per tonne to cost per piece or per metre using the weight of each item, so quotes and invoices can use any unit.
Scrap, crop ends and offcuts are weighed, valued at the current scrap rate and credited against the cost of the batch or heat they came from.
Yes. Each heat carries its own material and conversion cost, linked to heat tracking, so margin can be seen down to the heat and order.
Raw material and scrap rates can be updated daily, and the ERP shows the effect on stock value and on quotes.
