Our standard cardboard storage boxes are designed and manufactured so they are resistant to compression forces. This is highly advantageous when stacking either on a pallet for shipment or in your attic. We manufacture our stock double wall corrugated boxes out of 125 Kraft/125 Test B/C, which is 6.5mm thick. Some of our standard cardboard boxes are multi depth. This means the height can be altered to make the boxes smaller, which is useful for saving money on delivery costs or room in your garage. Buying directly from the manufacturer and cutting out the middle man will save you money as you will be buying at trade prices.
