Common questions
What does ECT-32 mean and why does it matter?
ECT (Edge Crush Test) measures how much pressure a corrugated box can withstand before crushing. ECT-32 rating means each linear inch of the box edge can support 32 pounds of force, making it ideal for stacking multiple boxes on pallets and surviving standard shipping conditions without product damage.
Can these boxes replace mailing tubes?
Yes. The 5512" dimensions and ECT-32 strength make these boxes an effective, cost-efficient alternative to mailing tubes for shipping poles, rods, and similar tall items while offering better stackability and easier packing workflows.
How many boxes fit on a standard pallet?
When assembled, a 5512" box is compact and highly stackable. Flat, a bundle of 25 takes minimal space. Consult your warehouse layout or contact our team for specific pallet configuration recommendations for your volume.
What's the actual cost per box when ordering in bulk?
The 25-box bundle pricing provides significant per-unit savings compared to smaller quantities. Request a bulk quote for volumes over 500 boxes to unlock additional volume discounts and explore custom pricing for your operation.
