Custom Corrugated Boxes & Wooden Pallets

ECT stands for Edge Crush Test, which measures a corrugated box's resistance to top-to-bottom compression — critical for stacked palletized shipments. Common ratings include 32 ECT (standard single wall), 44 ECT (double wall), and 48 ECT (heavy-duty double wall). ECT-rated boxes are preferred by major carriers like UPS and FedEx.

They are required when shipping materials to military installations or under government contracts that mandate weatherized, coated corrugated packaging.
