The BSC PREFERRED HD1818 is a heavy-duty single wall corrugated shipping carton designed for bulk cargo packaging applications. Constructed from 275 lb burst-rated, ECT-44 single wall kraft corrugated board, these cartons deliver 40% greater stacking strength than standard shipping containers. Each pack contains 20 cartons sold and shipped flat, making storage and staging straightforward in warehouse or shop environments. This SKU is equivalent to part number S-4730. Packaging professionals, warehouse staff, and shipping departments handling heavy or oversized trade supplies are the primary users of this product.
These cartons are suited for bulk cargo and heavy-load shipping scenarios where standard corrugated boxes fall short on compression and puncture resistance. The 275/ECT-44 specification makes them appropriate for palletized freight, stacked storage, and shipments subject to rough handling. They are commonly used in distribution centers, HVAC and plumbing supply houses, and industrial shipping operations where box integrity directly affects freight damage rates.
Designed as a heavy-duty corrugated carton for general bulk cargo and industrial shipping applications. This item is equivalent to part number S-4730.
No tools or trade licensing are required for assembly. Cartons ship flat and should be squared and taped prior to loading. Store flat bundles in a dry location away from moisture to preserve board integrity and compression strength. Inspect cartons for delamination or water damage before use in critical freight applications.
