Logistics & Transport Recommendations

Pallet Packaging Rule

Safe stacking limit: 11 pieces per pallet to stay within the 2,500 lbs standard wood pallet rating.

NMFC Item Guidance

Reference code: 90000 (Granite Slabs & Countertops). Rated under Class 50 based on 168 PCF density.

  • Shipment utilizes 2.5% of a standard 53ft trailer's 45,000 lbs legal cargo payload (43,880 lbs capacity remaining).
  • Standard GMA pallet recommendation: Maximum 11 units per pallet to remain within the 2,500 lbs safe working limit.

Shipping, Packaging & Stacking Specifications for Granite

Transport & Palletizing Rules

NEVER lay granite slabs flat during transport! Must be loaded vertically on heavy-duty steel A-frames clamped with timber.

Typical Industrial Applications
  • Kitchen countertops
  • Monuments & headstones
  • Floor tiling & stairs
  • Building cladding
Critical Handling Cautions:
  • Laying flat will cause slabs to crack in half under trailer vibration
Material density and metallurgical weight benchmarks correspond to standard test specifications from ASTM International and density rating tables from NMFTA.
