Logistics & Transport Recommendations

Pallet Packaging Rule

Safe stacking limit: 937 pieces per pallet to stay within the 2,500 lbs standard wood pallet rating.

NMFC Item Guidance

Reference code: 156600 (Plastic Cellular Foam). Rated under Class 250 based on 2 PCF density.

  • Shipment utilizes 0% of a standard 53ft trailer's 45,000 lbs legal cargo payload (44,987 lbs capacity remaining).
  • Standard GMA pallet recommendation: Maximum 937 units per pallet to remain within the 2,500 lbs safe working limit.

Shipping, Packaging & Stacking Specifications for PU Foam 2lb

Transport & Palletizing Rules

Extreme Cube-Out cargo! 53ft trailer will hold ~3,500 cubic feet but only weigh 7,000 lbs. Billed at high cubic freight rate.

Typical Industrial Applications
  • Reefer trailer insulation
  • Cooler & freezer panels
  • Floatation docks
  • Roof insulation boards
Critical Handling Cautions:
  • Do not over-tighten ratchet straps or foam boards will crush and snap
Material density and metallurgical weight benchmarks correspond to standard test specifications from ASTM International and density rating tables from NMFTA.
