Haiwang heavy duty shipping boxes carry loads of up to 3 tonnes in double wall and triple wall corrugated board. Choose telescopic, sleeve or die-cut construction, built to your exact dimensions and shipped flat from our factory near Qingdao Port. They replace wooden crates without fumigation, weigh far less, and recycle as a single material.
Triple wall board on a pallet base carries up to 3,000 kg. Double wall grades start at 80 kg.
Our heavy duty shipping boxes arrive flat-packed, saving container space and warehouse room compared with assembled crates.
BC double wall and AAA triple wall board, made on our 2,800 mm Marquip corrugator.
Corrugated packaging is exempt from ISPM 15. Pair it with our corrugated pallet base and the whole shipment clears without heat treatment or stamps.
Wooden crates are heavy, need ISPM 15 treatment and take up space even when empty. Heavy duty cardboard boxes in triple wall board give most industrial cargo the stacking strength it needs at a fraction of the weight, fold flat for storage, and go straight into paper recycling at destination. We engineer all our heavy duty shipping boxes to your load, test samples in our own lab, and only then start production.

Four standard grades, from double wall corrugated boxes to triple wall boxes on a pallet base. Every order is engineered and tested for your load and shipping route. Haiwang heavy duty shipping boxes are made to your dimensions in A, B, C and E flutes, with loads up to 3,000 kg.
Typical values for reference. ECT 1 lb/in ≈ 0.175 kN/m · Burst 1 psi ≈ 6.9 kPa.

How we make heavy duty shipping boxes, from your drawing to delivery in four steps.
Send your dimensions, cargo weight and route. We recommend the wall, flute and structure.
A physical sample in 5–7 days, tested for ECT, BCT and burst.
Bulk run on our Marquip and Shinko lines with in-line quality checks.
Flat-packed, palletized and shipped FOB Qingdao or door to door.
Measures the stacking strength of the board edge.
Confirms how much top load the finished box holds.
Checks resistance to puncture and internal pressure.
Verifies the strength of liner and medium papers.
Checks flute rigidity under flat pressure.
Ensures the layers stay bonded under load.
Answers to the questions buyers ask most about heavy duty shipping boxes.
It depends on the grade and structure. Our double wall boxes carry up to 80 kg, heavy double wall up to 250 kg, triple wall up to 1,000 kg, and triple wall boxes on a pallet base up to 3,000 kg. We confirm every design with compression testing before production.
For most machinery and parts under 3 tonnes, yes. Triple wall boxes are lighter, need no ISPM 15 fumigation and ship flat. For very dense or sharp-edged loads, we combine a corrugated sleeve with a corrugated pallet base, so the shipment stays wood-free.
No. ISPM 15 applies to solid wood packaging. Corrugated board is a processed paper product and is exempt, so no fumigation, stamp or certificate is needed.
Yes. Every box is made to your inner dimensions. Our 2,800 mm corrugator produces boxes up to 2,400 mm long.
Telescoping boxes and sleeves fold into shape in minutes, with no tools. We include an assembly sheet with every order and can add slots for strapping.
Yes. Add our water-resistant treatment, Cobb < 30 g/m², for humid routes, cold storage and outdoor yards.
