Common questions
What does ECT-90 mean, and why does it matter for my warehouse?
ECT-90 (Edge Crush Test) measures the corrugated's compressive strength, 90 lbs per linear inch. Higher ECT ratings mean the sheet resists punctures from forklift tines and pressure from stacked loads, directly reducing product damage and freight loss in your fulfillment center.
How many 40x48 sheets do I need per pallet?
Typical usage is 1, 2 sheets per pallet layer, depending on product weight and stacking height. For appliances averaging 150, 300 lbs per unit, one sheet per layer provides adequate separation and protection. Calculate total pallet layers and order in bundles of 5 for cost efficiency.
Will triple wall corrugated work with my existing pallet dimensions?
Yes. The 40 x 48" footprint is the North American standard for most warehouse racking and pallet equipment. These sheets integrate directly with stringer pallets, deck pallets, and block pallets without requiring equipment modifications.
Can I stack these sheets, or do they need to stay flat?
Triple wall sheets maintain structural integrity when stacked flat in storage or in palletized bundles. Store in a dry environment to preserve kraft strength and prevent edge softening that could compromise ECT performance.
