6x6x30 Kraft Corrugated Shipping Boxes

A standard single-wall 6x6x6 corrugated cardboard box typically weighs between 3 and 5 ounces (approximately 85–140 grams), depending on the flute type and board grade. ECT-32 rated boards may weigh slightly more than standard 200# burst-strength boards. Always verify exact weights with the supplier when calculating shipping dimensional weight charges.

Custom size shipping boxes are available directly from Cardboard Boxes 4 U. You can request custom dimensions online or by calling (888) 333-9513. Custom corrugated boxes are produced in 7–10 business days with minimum order quantities starting at 100 pieces. A custom box calculator tool is also available online for self-service sizing and pricing estimates.

These long, narrow boxes are ideal for shipping rods, pipes, posters, curtain rods, fishing rods, golf clubs, and other elongated items. They are widely used in e-commerce fulfillment, retail packaging, industrial shipping, and moving applications where standard square boxes cannot accommodate the product dimensions.

Single-wall corrugated construction with an ECT-32 or 200# burst-strength rating is sufficient for most standard shipping needs in this size range. For heavier or fragile elongated items, a heavy-duty or double-wall variant provides additional stacking strength and impact resistance during transit via UPS, FedEx, or freight carriers.
