Stage 1 — Gate inspection on inbound trucks
Every inbound truck is weighed on a calibrated 60-tonne weighbridge, photographed and visually graded against ISRI master samples by the yard supervisor. Lots that fail visual grade are tagged and routed to the re-sort bay; they are not paid for at the supplier rate until re-graded. Moisture, contamination and unauthorised attachments are flagged at this stage to prevent yard-level grade drift.
