Product Introduction
G655 granite is quarried at Tong'an in Fujian Province, where the deposit yields a white ground carrying fine grey mineral speckle - the material traded internationally as Tong'an White and, in some markets, as Sunny White. YoYo Stone buys this stone as first-hand blocks and keeps consecutive lots together through sawing rather than drawing from the spot market, which is what holds tone stable across a project.
Countertop programs run to roughly 25,000 m² a month across two shifts, with five gang saws feeding the CNC centres. Every order is fabricated to your shop drawings: sink and hob openings nested to the cabinet plan, edge profiles cut to the specified radius, and each piece stamped with its run position before crating.

Quality Standards
Quality Control & Inspection Standards
YoYo Stone enforces strict, metric-based quality assurance protocols across every production phase to eliminate on-site fitting discrepancies and guarantee structural reliability for large-scale contract orders.
CAD Ingest & Cutout Nesting
Shop drawings are re-nested before cutting so sink and hob openings clear cabinet rails, drawer boxes and corner posts.
01
Sequence Numbering at Layout
Each piece is stamped to its run position during trial assembly, so the install crew works from a numbered stack.
02
Run Closure Gauging
Openings, edge returns and splash joints are measured after assembly rather than piece by piece.
03
Crate Against the Run
Crates are packed in installation order, so the first pieces off the truck are the first pieces set.
04
Products Application
Typical Project & Application Scenarios
High-Volume Commercial & Hospitality Developments
Custom-fabricated granite countertops, island slabs, and vanity surfaces built to withstand aggressive sanitation chemicals, high moisture, and heavy daily utility across multi-family housing programs, hotel foodservice facilities, and commercial restrooms.
Designed with high flexural strength and low water absorption, these tops resist thermal shock, daily food acidic spills, and severe mechanical abrasion in high-traffic common areas. Our automated factory lines ensure precise CAD-guided sink cutouts, uniform edge profiling, and sequential color-matching, guaranteeing long-term durability and seamless installation across multi-unit commercial developments.
Wholesale & Building Supply Distribution
Bulk-packed crate assortments of standardized prefabricated countertop dimensions and custom cutouts, engineered for regional stone distributors stocking high-demand inventory for commercial contractors.
These standardized volume packages feature pre-calibrated edge profiling and pre-sealed surfaces, enabling rapid job-site deployment without requiring extensive secondary fabrication. By aligning crate loading specs directly with regional transport weight limits, we help distributors optimize warehouse space, streamline inventory turnover, and reduce landed freight costs per unit.
FAQ
Everything You Want To Know
01. How is colour held consistent across the countertops in a multi-unit order?
We buy blocks from one bench of the Tong'an deposit at a time and keep them in a single lot through sawing. Pieces are then sorted by tone into matched sets during trial assembly. Tops for different floors are never drawn from separate lots.
02. What protects the surface against oil, wine and freeze-thaw cycling?
03. How are crates built for a 20 ft container, and what breakage allowance should we plan?
04. How are sink and hob cutouts set so they clear cabinet rails on site?
