EN 10204 · 2.1 to 3.2HEAT & CAST GENEALOGYDATABASE IN LONDON

Everything the office and the warehouse run on.
Purchasing, stock, production, despatch and finance work from the same batch record, so nothing is keyed twice.
Sales orders
Quote to order with credit, stock and certificate gates before anything leaves the warehouse.
Goods receipt & weighing
Book in from the delivery note; confirm actual weight later. Unweighed stock can't be sold.
Stock & warehousing
Every physical lot is a batch: heat, cert, weight, cost and bin location.
EN 10204 traceability
Mill certificates matched to batches by heat number. Types 2.1 to 3.2, ranked.
Subcontract processing
Send material out for machining or testing. It returns costed, certified and traceable.
Customer portal
Customers fetch their own delivery notes, cert packs, invoices and statements.
AI assistant
Ask your live data a question and get a table or a chart. Actions run only once you confirm.
Accounts export
Ledger-ready CSV for your accounting package, from posting runs and part-payments.
Reporting
Margins, stock age, OTIF, aged debt. Live screens, not month-end spreadsheets.
Cut-piece pricing
Chargeable length with kerf and facing allowance, priced by saw type.
Generic ERPs don't know what a heat number is.
MetlSys was modelled on the steel trade, not adapted to it afterwards. The things generic stock software cannot do are the point.
Catch-weight, dual units
Theoretical and actual weight on every batch. Price per kg, metre or each. Invoice on either weight basis, with the variance flagged for review.

Heat & cast genealogy
Split it, cut it, send it out for machining. Every child batch keeps the parent’s heat, certificate and cost history. Remnants stay sellable and traceable.
