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: 13120 (Aluminum Sheet/Plate). Rated under Class 50 based on 169 PCF density.

  • Shipment utilizes 2.5% of a standard 53ft trailer's 45,000 lbs legal cargo payload (43,873 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 Aluminum 6061

Transport & Palletizing Rules

Lightweight structural alloy (~1/3 the weight of steel). Ships in wooden skids or crates to prevent corner bending.

Typical Industrial Applications
  • Aircraft fittings
  • Automotive frames
  • Bicycle frames
  • Marine hulls & walkways
Critical Handling Cautions:
  • Softer than steel; forklift tines easily gouge bare billets
  • Moisture between stacked sheets causes white rust oxidation
Material density and metallurgical weight benchmarks correspond to standard test specifications from ASTM International and density rating tables from NMFTA.
