PROJECT GRANITE FAQ ## Questions engineering granite buyers ask **Direct answer:** Project granite procurement works best when material, sample, drawings, dimensions, quantity, finish, tolerance, packing and schedule are written as one common standard. Quotation, production, inspection and delivery should follow that information, not price per square or cubic metre alone. Updated 2 September 2026 · First-party source: current product, capacity and quality-process information supplied by Shandong Kaizhong Stone Co., Ltd. **Buyer takeaways** - Standardise specification and acceptance before comparing price. - Control appearance through sample, block batch and colour sorting. - Put tolerance, edges, holes and custom details in drawings. - Capacity is not a fixed lead-time promise.

Provide the granite name or reference sample, drawings, length, width, thickness, quantity, finish, tolerance, packing, delivery location or destination port and required arrival date. Custom components also need complete CAD drawings. ### 02How is colour variation controlled for a volume granite order? Approve a representative physical sample and allowed variation range, organise production by block batch, and agree colour sorting, numbering or dry-lay inspection before packing. Put the final standard in the order or inspection document. ### 03Does published factory capacity guarantee a project lead time? No. Capacity data describes underlying machinery and production conditions. Lead time still requires written confirmation against granite, dimensions, thickness, quantity, finish, packing, transport and the current production schedule. ### 04Which granite thicknesses are commonly requested? Project enquiries commonly include 20, 30 and 50 mm, but final thickness must follow loading, installation method, conditions of use and approved design drawings. A common value is not a substitute for engineering selection. ### 05Where are flamed and bush-hammered finishes commonly used? They are commonly considered for exterior paving, plazas, paths and steps where a pronounced texture is needed. The project designer must define slip requirements and applicable standards, while a physical sample confirms appearance. ### 06When should an international buyer audit the factory? For volume orders, custom fabrication, short schedules or complex acceptance criteria, audit blocks, machinery and work in progress before ordering. Review finished goods, packing, shipping marks and the dispatch area again before shipment. ### 07How should dimensional and fabrication tolerances be confirmed? Define length, width, thickness, diagonals, edges, holes, curves and permitted deviations in the drawing before production. Also agree the measurement method, sampling rate and handling of non-conforming pieces. ### 08What should be confirmed for export packing? Confirm crate or pallet type, package weight, corner protection, separators, straps, shipping marks, packing list and any wood-packaging documents required by the destination market. Match the packing plan to product size, weight and transport mode. ### 09How can a buyer obtain a more accurate quotation? Send drawings, size schedule, quantity, finish, acceptance requirements, packing, destination port and required arrival date together. State the quotation scope and trade terms so suppliers are compared on the same basis. ## How should these answers be used in a real order? Use this page as the starting checklist, then add the requirements of the design, conditions of use and purchase contract.
