Steel Inventory Management: Heat, Weight and Remnant Records
Track steel by grade, heat, measured weight, unit conversion, cut issue, reusable remnant, rejection and complete quantity reconciliation.

Steel inventory management must preserve grade, heat or lot, dimensions, measured weight, location and usable condition. After cutting, the original quantity should reconcile to issued material, reusable remnant, process scrap and rejection.
A stock line that says “plate: 2 pieces” cannot answer whether the available plate has the right grade, heat, dimensions or usable weight. Steel inventory needs both commercial units and production evidence.
Receive the material with its identity
| Event | Piece identity | Grade / heat | Weight | Result |
|---|---|---|---|---|
| Receipt | PL-001 | IS 2062 / H778 | 520 kg | Accepted in raw store |
| Receipt | PL-002 | IS 2062 / H779 | 515 kg | Held for document check |
| Cut issue | PL-001 | IS 2062 / H778 | 400 kg | Issued to WO-881 |
| Remnant | REM-001 from PL-001 | IS 2062 / H778 | 112 kg | Reusable; Rack R4 |
| Process scrap | From PL-001 | IS 2062 / H778 | 8 kg | Scrap bin S2 |
PL-001 reconciles: 400 + 112 + 8 = 520 kg. PL-002 exists physically but is not usable until its hold is resolved.
Control unit conversion
Buying by piece and consuming by kilogram requires a defined conversion basis and an actual measurement where the process depends on weight. Keep nominal and measured values distinguishable. Do not change the item balance using an estimated conversion without the rule and approval.
ERPNext stock-entry documentation provides a primary example of how material movements can link to manufacturing records.
Use Optiwise for steel stock records
Optiwise connects item and UOM masters, receipts, inspections, stores, material issue, production orders and movement history. Configurable fields can capture grade, heat, dimensions and remnant identity within the relevant workflow. Item barcodes help keep the physical piece tied to its record.
Follow the material in inventory, its work order in production and any hold in quality.
Test the remnant workflow
Ask the ERP demo to cut one plate, return a reusable remnant, move that remnant to another rack and issue part of it to a second work order. The test should preserve the parent piece, grade/heat and every quantity change.
Questions from manufacturing teams
Should steel be tracked by pieces or weight?
Often both. Use the commercial and operating units your process needs, with controlled conversions and actual measurements where required.
What makes a remnant reusable inventory?
It needs an identity, grade or heat, dimensions, usable condition, measured quantity and known location.
Can ERP replace a mill test certificate?
ERP can store and link document references. It does not create or validate the technical certificate unless that process is explicitly implemented.
