GRANITE FACTORY AUDIT ## What should a project granite buyer inspect at the factory? **Direct answer:** An effective granite factory audit goes beyond buildings and machine counts. Follow a real enquiry through six areas: company identity, block batches, relevant machinery, dimensional and finish inspection, project scheduling, and packing and dispatch. Each check should connect to a current site view, the target product or a corresponding written record, with final commitments placed in the order. Updated 2 September 2026 · Baseline data supplied by Shandong Kaizhong Stone Co., Ltd. and available for on-site or live video review **Audit principles** - Inspect against one real specification or enquiry list. - Separate machine count from usable project processes. - Separate company capacity from the project schedule. - Record observed conditions separately from contract commitments. - Do not conclude from unverified test values or cases. ## Company-reported capacity baseline These company-level figures are supplied by Shandong Kaizhong Stone Co., Ltd. to frame audit questions. They do not represent capacity reserved for one project or guarantee a delivery date. **180 mu** Company-reported production-base area **26** Large cutting machines **15** Mid-size cutting machines **11** Infrared bridge saws **25–30 truckloads/day** Company-reported routine dispatch capability **Approx. 28,000 m³/year** Kerbstone capacity **Approx. 1.8–2.0M m²/year** Slab capacity **5M+ m²/year** Total granite-product capacity ## Six audit stages and expected evidence 01 / AUDIT ### Company identity and order responsibility - Reconcile quotation, contract, payment and invoicing entities - Confirm product scope, project contact and after-sales responsibility - Request company or export records required by the order **Suggested evidence:** Company records, quotation, contract sample and a named responsible contact 02 / AUDIT ### Blocks and batch readiness - View blocks or semi-finished stock for the selected granite - Confirm how batches, colour range and approved samples correspond - Ask how a volume project handles shortage or batch change **Suggested evidence:** Live block-yard view, batch marks, physical sample and material plan 03 / AUDIT ### Machinery and actual processes - View cutting and surface equipment relevant to the order - Confirm operating status and applicable dimensions - Follow one product from cutting to finished stage **Suggested evidence:** Continuous live view, workstations, work in progress and process explanation 04 / AUDIT ### Dimensions and surface quality - Observe thickness, length, width and diagonal measurement - Compare the finish with the approved sample - Review colour sorting, dry lay and non-conformance isolation **Suggested evidence:** Measuring tools, inspection record, sample, dry-lay area and exception handling 05 / AUDIT ### Capacity and project schedule - Translate order quantity into actual fabrication and packing workload - Review current work in progress and available processes - Confirm material, sample, production, inspection and dispatch milestones **Suggested evidence:** Project schedule, work in progress, material status and written milestones 06 / AUDIT ### Packing and dispatch - View pallets, crates or supports used for a comparable product - Confirm case numbers, labels, packing list and photograph records - Check loading, container or vehicle limits and site unloading conditions **Suggested evidence:** Actual packing, sample labels, packing documents, dispatch area and transport plan ## How to verify whether the schedule is workable | **Audit question** | **Relevant site view or record** | **Confirm in the order** | | --- | --- | --- | | Is material ready? | Selected blocks, semi-finished stock, batch and material plan | Granite, sample, batch rule and replenishment | | Do processes match? | Equipment, workstation and work in progress for the actual sizes | Key processes, finished faces and custom details | | Can production be scheduled? | Current work, available shifts, inspection and packing resources | Sample, production, inspection and dispatch milestones | | Is quality traceable? | Measurement, inspection, sorting, dry lay and exception isolation | Tolerance, sampling, colour range and rework rules | | Is logistics coordinated? | Packing area, dispatch area and vehicle or container conditions | Packing list, labels, weight, destination and arrival date | ## Limits of a factory audit An audit records conditions observable during the visit or live connection. It does not replace physical testing for the selected granite and does not automatically create price, quality or delivery commitments. Final acceptance follows approved samples, drawings, technical criteria, packing attachments, contract and written order.

FACTORY AUDIT FAQ ## Questions about auditing a granite factory ### What is the difference between an on-site and live video factory audit? An on-site audit better reveals site flow, scale, multiple processes and original records. A live video tour supports initial screening or remote verification. Ask for a continuous view of specified areas, the current date context and the target product rather than only edited footage. ### Does a higher machine count guarantee on-time delivery? No. Lead time also depends on selected granite, material readiness, size mix, finishes, current production, inspection, rework, packing and logistics. Machine count is a capacity signal, not a project delivery guarantee. ### How can a buyer verify dimensional control? Ask the factory to select a product close to the order and measure thickness, length, width and diagonals with the agreed tools. Confirm sampling frequency, tolerance and exception handling in the drawing or order. ### How should colour control be audited for a large area? Review block batches, approved samples, colour-sorting areas and dry-lay practice, then request written rules for replenishment, batch change and acceptable variation. A small sample cannot represent every area-wide variation. ### What still needs written confirmation after an audit? An audit shows conditions observed at that time. Granite, samples, drawings, tolerance, quantity, finish, packing, documents and lead time still belong in the contract, order or approval attachments. ## Book an audit with the product list Send granite, dimensions, quantity, finish, required delivery and the processes you want to inspect.
