Application Scenarios & Solutions

Material stone is used across diverse applications. Below are common scenarios and tailored solutions:

10 Frequently Asked Questions (FAQs)

1. What is the difference between granite and marble? Granite is harder and more durable, while marble is softer and more porous, often used for aesthetics.
2. Is engineered quartz better than natural stone? Quartz is non-porous and requires less maintenance, but natural stone offers unique veining and value.
3. How do I clean stone countertops? Use pH-neutral cleaners; avoid acidic or abrasive products.
4. What is the average lifespan of stone flooring? With proper care, natural stone can last 50-100 years or more.
5. Can stone be used outdoors? Yes, but choose dense stones like granite or basalt and seal them properly.
6. How do I match stone colors across slabs? Request book-matched or lot-matched slabs from the same quarry block.
7. What is the best finish for a kitchen countertop? Honed or leathered finishes hide fingerprints and etch marks better than polished.
8. Are Chinese stones lower quality? Not necessarily; quality varies by manufacturer. Many Chinese factories produce premium-grade stone.
9. 中国からの発送にはどのくらい時間がかかりますか？ Sea freight typically takes 20-40 days depending on the destination port.
10. What is the minimum order quantity (MOQ) for stone? MOQ varies but often starts at 100-200 square meters for slabs.

Procurement Precautions

• Verify Quarry Ownership: Ensure the factory controls its own stone source to avoid supply disruptions.
• Request Third-Party Testing: Test for radon emissions, water absorption, and flexural strength.
• Clear Payment Terms: Use letters of credit (L/C) or escrow services for large orders.
• Inspect Before Shipment: Hire an inspector to check for cracks, color consistency, and dimensional accuracy.
• Understand Incoterms: Clarify whether FOB, CIF, or EXW terms apply to avoid hidden costs.
• Check Export Licenses: Ensure the supplier has valid export permits and customs documentation.
