Zero-Defect Commitment

Multi-Tier Quality Control & Laboratory Inspection

Rigorous quality auditing protocols ensuring international stone buyers receive 95%+ size uniformity and clean, dust-free packaging in every container.

Quarry Material Auditing

Raw stone blocks are sampled at quarry source to verify mineral purity, color consistency, and structural density.

Multi-Deck Sieve Analysis

Vibratory deck screeners separate aggregate sizes into strict millimeter channels with ±1mm sizing tolerance.

Double Optical & Hand Sorting

Stones pass through illuminated conveyor belts where operators remove fractured or discolored pebbles.

Dust Washing & Kiln Drying

Stones undergo triple-water washing channels to eliminate clay dust, followed by rotary kiln drying.

Pre-Stuffing Container Audit

Every pallet is inspected for weight accuracy, bag seal strength, and ISPM-15 phytosanitary markings.
