Natural limestone is a geological material with inherent vein and fossil movement. Tianya eliminates job-site shade shock through a mandatory 6-Stage Quality Control Gate culminating in a 3,000 m² indoor dry-lay pre-blending inspection where tiles from multiple blocks are mixed, numbered, and photographed before crating.

Applicable Scope & Boundary Conditions: Mandatory QC protocol for all architectural project orders and full-container distributor shipments.
| Verification Dimension | Authoritative Evidence & Technical Specification |
|---|---|
| Dimensional Calibration | Infrared bridge saws and multi-head diamond calibrators hold thickness tolerance to ±1.0 mm (15–20mm tiles) and ±1.5 mm (30–50mm pavers), exceeding EN 1341 Class T2. |
| Moisture & Efflorescence Control | Kiln/air-cured below 1.5% residual moisture prior to optional factory 6-sided pre-sealing and polyethylene-lined crating. |
| Batch Traceability | Every crate bears a unique QR/barcode linking back to the quarry bench, gang-saw block number, CNC operator, and dry-lay inspection photo set. |
By pre-blending tonal variations across crates in our 3,000 m² hall, installers can pull directly from sequential crates without sorting hundreds of heavy slabs on a cramped job site, reducing laying time by 20–30%.
Any slab exhibiting structural micro-fissures, corner spalls >2mm, or out-of-range calcite blotches is rejected on the factory floor and replaced from the same quarry block before crating.
