Description

The 18 x 18 x 18 inch triple wall corrugated box is a heavy-duty RSC (Regular Slotted Container) engineered for loads and transit conditions that single or double wall corrugated cannot reliably handle. Built to ECT-90 standards with over one-half inch of combined board thickness, it delivers structural rigidity comparable to a plywood crate at a fraction of the weight.

The equal cubic interior suits dense or irregularly weighted products that demand maximum compression and stacking resistance — common requirements in automotive parts distribution, industrial equipment shipping, metal component packaging, and export freight preparation. The RSC design assembles without special tooling, keeping line setup simple in high-throughput environments.

Each bundle contains 5 boxes, with each weighing approximately 7.24 lbs. Ships via parcel carrier, making smaller reorders practical without pallet-quantity commitments.
