What to check in a stone factory audit, and in what order
The order is block yard, saw, polisher, cutter, packing — and the showroom last. The yard shows whether material exists, the saw shows capacity, the polisher shows surface quality, the cutter shows accuracy, packing shows whether the goods survive the voyage.
Why start at the block yard?
The yard tells you two things: whether there is material on hand, and whether block supply is stable. An empty yard with a promise of stock on demand means either a trader or a wait. A yard full of unrelated varieties means they take any order and quality control is luck.
What do the saw and the polisher tell you?
The block saw sets capacity; the polisher sets surface quality. Check whether polishing is automatic or manual: hand-polished panels vary in gloss within the same batch. Both are heavy capital equipment that cannot be rented or faked, which makes them the best evidence of real capacity.
Why do cutting and packing matter so much?
Cutting determines dimensional accuracy; packing determines whether the shipment arrives intact. Look for infrared positioning on the cutter, and for whether packing is a wooden bundle or a crate, with corner protection and moisture barrier. These two are the most neglected and the most likely to surface only at destination.
Why leave the showroom until last?
A showroom is a curated display. It cannot show batch variation or real capacity. Walk the first four stations before the showroom and your questions change completely, from how beautiful this is to how far it drifts from the last batch.
What if you are still not comfortable?
Place a small trial order. Run one full cycle at the minimum quantity: sample approval, production clips, pre-loading inspection. One completed cycle tells you more than any audit report, because you have tested the process rather than the promise.
