48 x 48" Triple Wall Corrugated Sheets

These 48 x 48 inch triple wall corrugated sheets are built from ECT-90 kraft corrugated board, delivering exceptional compression strength and puncture resistance well beyond what single or double wall material can provide. At approximately 5.24 lbs per sheet, the dense multi-wall construction supports substantial load-bearing demands in high-stress packaging and industrial environments.

The square footprint aligns with standard pallet dimensions, making these sheets a natural fit as tier sheets between stacked pallet loads. They also serve as protective interleaving for heavy machinery, appliances, metal stampings, and cast components, and as dunnage or floor protection inside freight shipments where surface damage or load shift is a concern.

Sheets are sold in bundles of 5 and ship via parcel carrier. The ECT-90 triple wall rating reflects a three-layer fluted construction engineered for high compression and puncture resistance across repeated handling cycles. Orders can be placed in any quantity to support ongoing warehouse, staging, or manufacturing floor requirements.
