1.Ultrasonic Flaw Detection And Micro Fissure Screening In Raw Blocks

Raw granite selection determines the structural performance of finished monuments. Monument grade stone blocks require ultrasonic flaw detection, micro fissure screening and internal structure inspection before cutting. Granite with density around 2.9g/cm³ and water absorption below 0.2% is commonly selected for outdoor headstones exposed to long term weather conditions.

Quarry inspection begins before block transportation. Each raw block is checked for internal cracks, uneven mineral distribution and hidden fractures that may affect CNC cutting, Sandblasting and Hand carving statuary processes.

Micro fissures inside granite may expand during temperature changes or overseas transportation. Early detection reduces production loss during carving, polishing and final monument assembly.

2.Physical Density And Water Absorption Thresholds For Outdoor Durability

Density Testing Standards For Long Term Monument Performance

Stone density and water absorption directly influence freeze thaw resistance, surface stability and maintenance requirements. Before production, selected granite blocks undergo density testing and water absorption evaluation.

Low water absorption granite reduces moisture entry into microscopic pores, helping prevent staining, cracking and surface deterioration. These specifications are important for cemetery installations exposed to rain, snow and seasonal temperature changes.

Mineral Composition Uniformity To Eliminate Natural Iron Spots

Mineral Testing Standards For Clean Granite Surfaces

Natural granite contains different mineral components including quartz, feldspar and mica. Uneven mineral distribution may create color variation, dark spots or iron oxidation marks after outdoor exposure.

Production controls include:

Mineral composition checked before block approval
Iron spot risks evaluated through quarry inspection
Color vein direction recorded before cutting
Surface samples reviewed under natural lighting
Final stone selection matched with approved reference samples

Consistent mineral structure supports Laser etching contrast, Sandblasting clarity and polished surface quality for memorial applications.

3.Quarry Origin Verification For Consistent Color Vein Sourcing

Quarry origin verification ensures stable supply of matching granite materials for repeated monument orders. International retailers and cemetery operators require consistent color, texture and physical performance across multiple production batches.

Our sourcing process includes:

Quarry location verification
Raw block identification records
Batch color comparison
Density test documentation
Export packing inspection

Each approved Monument grade block is processed according to confirmed specifications. Export shipments use Export grade 2cm wooden crates with reinforced internal protection to reduce transportation damage.
