Heavy Duty Triple Wall Boxes

Triple wall corrugated cardboard is typically between 1 inch and 1.5 inches thick, depending on the flute profile used (commonly B, C, or BC flute combinations). The three layers of fluting significantly increase rigidity and stacking strength compared to single or double wall constructions, making it one of the thickest and most durable corrugated board configurations commercially available.

Triple wall boxes are available in various strength ratings including ECT-48 and higher, as well as Mullen/Burst Strength grades exceeding 200 lb. The appropriate rating depends on the weight and fragility of your contents and the shipping method used. Cardboard Boxes 4U offers multiple corrugated grade options to match UPS, FedEx, and freight carrier requirements.
