Common questions
What does ECT-48 mean and why does it matter for my warehouse?
ECT (Edge Crush Test) 48 means each inch of the sheet's edge can withstand 48 pounds of compression. For warehouses, this translates to reliable stacking performance, these sheets handle heavy pallet loads without crushing, reducing product damage claims and maintaining load integrity during multi-tier storage and transport.
How many layers can I stack with 40x48 double wall corrugated sheets?
Double wall ECT-48 sheets support 6 - 10 pallet layers depending on product weight and load distribution. Consult your specific product weight and warehouse conditions; heavier items may require fewer layers, while lighter goods can stack higher while maintaining structural integrity.
Will these corrugated sheets fit standard 40x48 pallets?
Yes. The 40" x 48" dimensions are engineered to match standard pallet footprints precisely, ensuring complete coverage without gaps or overhang. This maximizes load stability and minimizes product shifting during handling and transport.
Are these sheets reusable or single-use?
Double wall corrugated sheets are typically single-use for hygiene and damage prevention in most warehouse operations. However, if stored dry and handled carefully, premium-grade ECT-48 sheets can sometimes be reused 2 - 3 times before recycling, depending on product type and load weight.
