GRANITE LEAD TIME & SCHEDULING ## How should engineering granite lead time be confirmed? **Direct answer:** Granite lead time cannot be calculated from area or machine count alone. A workable schedule must confirm drawings, samples, material batches, size mix, quantity, processes, inspection and corrective work, packing and destination, then place six milestones—technical freeze, material, production, acceptance, packing and dispatch—in the written order. Updated 2 September 2026 · Capacity figures supplied by Shandong Kaizhong Stone Co., Ltd.; each project requires a written schedule **Scheduling principles** - Freeze technical information before confirming production dates. - Annual factory capacity is not reserved project capacity. - Sample approval, inspection and corrective work belong in the schedule. - Ex-works, shipment and arrival are separate milestones. - Every date needs prerequisites and a responsible party. ## Information required before scheduling | **Input** | **Confirm** | **Schedule effect** | | --- | --- | --- | | Product and drawings | Granite, product type, current CAD/PDF and part IDs | Defines material, machinery, processes and trial fit | | Sizes and quantities | Length, width, thickness, size mix, holes, slots and custom details | Defines cutting plan, process time and inspection workload | | Sample and finish | Colour range, flamed/bush-hammered/polished/honed finish and edges | Defines approval and surface-processing stages | | Quality and release | Tolerance, sampling, dry lay, third-party inspection and witness points | Defines inspection, corrective action and release time | | Packing and transport | Pallet/crate, piece and case weight, port or project destination | Defines packing, loading, documents and logistics | | Required date | Requested ex-works, shipment or arrival date and split-delivery need | Used for backward planning; not an automatic factory commitment | ## Six delivery milestones to place in the order - **Technical freeze** Approve the current drawings, cutting list, sizes, quantities, tolerances, faces and part IDs. - **Sample approval** Approve granite, colour range, finish, edges and visible-face appearance. - **Material and batch reservation** Verify blocks or semi-finished stock, batches, replenishment and batch-change rules. - **Production and in-process inspection** Schedule each process and record first article, dimensions, finish and exceptions. - **Final inspection and packing** Complete sorting or dry lay, final checks, case numbers, labels and packing photographs. - **Dispatch and arrival coordination** Confirm loading, documents, destination, unloading conditions and estimated arrival milestone. ## Six common causes of schedule delay 01 / RISK ### Drawing changes Changing sizes, quantities, holes or slots after scheduling affects material use, processing and inspection. 02 / RISK ### Complex size mix Multiple sizes, small batches, custom pieces and trial fitting increase process changes and identification work. 03 / RISK ### Late sample approval Production lacks a stable acceptance baseline until colour and finish samples are approved. 04 / RISK ### Material batch change Replenishment or a new batch may require colour selection, a new sample or dry-lay adjustment. 05 / RISK ### Inspection and rework Third-party inspection, witness points and corrective work require scheduled time. 06 / RISK ### Packing and logistics Crate rules, weight limits, booking, trucks, ports and unloading conditions affect dispatch. ## Company-reported capacity baseline These figures help buyers understand base capability and ask scheduling questions. They do not mean capacity has been reserved for a specific order. **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 ## Limits of lead-time information Machine counts and annual capacity indicate baseline fabrication capability but cannot determine one project date. Actual timing remains subject to material, drawing changes, size mix, current work, inspection and rework, packing, transport and external events.

LEAD TIME FAQ ## Questions about engineering granite lead time ### Is there a standard lead time for every granite order? No. Lead time depends on granite and batch, drawing completeness, size mix, quantity, finish, quality requirements, current production, packing and destination. A written schedule should be prepared for the specific enquiry. ### How can a buyer verify that a proposed schedule is workable? Ask the factory to connect the date to material status, relevant machinery, current work in progress, sample approval, production, inspection, packing and dispatch milestones, with responsibilities and prerequisites for each stage. ### When does the lead-time clock start? The order should define the starting condition, such as contract effectiveness, deposit, technical freeze, sample approval or material confirmation. Different starting conditions produce different dates; “after order” alone is ambiguous. ### Can a large project use split deliveries? Yes, subject to agreement. Build the plan around installation sequence, sizes, case numbers, quantity per batch and site demand, then confirm inspection, packing, transport and replenishment for each release. ### Are ex-works, shipment and arrival dates the same? No. Factory completion, loading, vessel shipment and project arrival are separate milestones. Procurement documents should state which milestone is committed and treat transport and customs uncertainty separately. ## Send the brief for a workable schedule Provide drawings, granite, sizes, quantity, finish, packing, destination and required date.
