Where these tools earn their keep
- Quoting. A contractor asks for 200 pieces of 12 mm TMT, or 40 lengths of 50 NB medium pipe. You need the tonnage and the value before you reply on WhatsApp.
- Loading. The truck is booked by weight. Pieces per tonne tells the yard how many to load.
- Checking the weighed load. Actual weight rarely matches the chart exactly. The standards allow a mass tolerance, and each chart page shows it, so you can tell a normal difference from a short load.
- Settling arguments. Older charts and mill catalogues differ in places. Each page names the edition and table it uses, so both sides can check the same figure.
Chart weight on the order, actual weight on the bill
A chart gives you the nominal weight. What you bill is what was actually loaded. In SteelERP each order line keeps both: the ordered weight and the actual loaded weight, with the invoice on the actual. Delivery sub-orders can be in kg, metres or pieces, and each has its own loading, challan and delivery status. GST (CGST/SGST/IGST with HSN) is on the order line, and printed challans can be pulled into Tally Prime.
