Introduction to Format Selection
Selecting between jumbo gangsaw granite slabs (20mm, 30mm) and calibrated granite tiles (10mm, 12mm, 15mm) impacts both structural engineering schedules and long-term facility maintenance cost.
1. Structural Integrity & Joint Minimization
Gangsaw slabs allow expansive continuous vein patterns and minimal grout joints, ideal for luxury hotel lobbies and high-footfall terminal concourses where seamless maintenance is mandatory.
2. Installation & Sub-Base Requirements
Calibrated tiles reduce dead-load weight per square metre, enabling rapid thin-set mortar installation on elevated skyscraper floors, while thick slabs demand specialized mechanical anchorage and high-load substructures.
3. Cost & Logistics Comparison
| Parameter | Gang Saw Slabs (20/30mm) | Calibrated Tiles (10-15mm) |
|---|---|---|
| Yield per Container | ~400-450 m² (20mm) | ~800-950 m² (10mm) |
| Installation Speed | Medium (Heavy Handling) | Fast (Standard Tile Crew) |
| Flexural Load Capacity | Ultra High | High (Requires Solid Subbase) |
