Tips for Purchasing Quartz Stone: Beyond Price Comparison, These Indicators Determine Project Success
In recent years, raw material and shipping costs have been fluctuating continuously. When overseas buyers select large slabs of quartz stone, they often simply compare the price per square meter, which can easily lead to mistakes. As a Chinese source factory of quartz stone, we have compiled the key points for purchasing and screening.
First, look at the formula: High-quality slabs have an quartz content of 90%-93%, while low-content slabs have a higher resin ratio, which makes them prone to yellowing and color bleeding in the future. You can request a third-party test report to verify the water absorption rate, stain resistance, and bending strength.
Second, check the color difference of batches: For large-scale construction projects, it is essential to confirm the factory's automated batching system to avoid color differences between batches, which can lead to installation rework and losses at the construction site.
Third, pay special attention to the export packaging and loading. Quartz stone is a heavy and fragile product. The wooden frame must undergo the ISPM15 standard for fumigation, and the slabs should be placed in a vertical A-shaped frame with foam isolation to reduce shipping damage. Recently, there have been frequent accidents involving maritime containers, so packaging quality directly determines the risk of cargo damage.
Also, confirm product certifications: Export to different markets requires certificates such as CE, NSF, and Greenguard. Check them in advance to prevent customs clearance delays at the destination port.
Lower price does not mean better value. Once there are issues such as staining, cracking, color difference, or cargo damage, the subsequent after-sales costs will far exceed the purchase price difference. The source factory supports sample sending and factory inspection. Based on the project budget, stable quality slabs can be matched.
