Your Professional Sintered Stone Supplier
Xiamen Smarter Stone was founded in September 2005. We established our own office in 2006 and later moved to the Wanda Plaza building in 2012. Since then, we have built a robust foreign sales team and experienced significant growth. Over the past 10 years, we have optimized our six main product categories, including artificial stone and natural landscape pavers. We also prioritize staff training through various lessons to enhance our customer service and adopt a customer-oriented approach.
Sintered stone slabs are manufactured by compacting wet-processed clay, feldspar, and natural quartz powder under pressures exceeding 400 MPa before firing in kilns at temperatures above 1200°C. This sintering process creates a dense, non-porous material with zero binder resins, making it suitable for both indoor vanity tops and outdoor ventilated rainscreen facades.
