Ultra Heavy Duty Cardboard Tubes — 4mm Wall, Maximum Protection

Our ultra heavy duty cardboard tubes are spiral wound with a 4mm wall — the thickest tube we stock and a full third stronger than our 3mm extra heavy duty range. They are built for the toughest despatch jobs: heavy fabric rolls, engineering drawings, steel rule, oversized canvas, industrial cores and any high-value item that must arrive without a dent.

When to choose a 4mm ultra heavy duty tube

• Very heavy contents — thick fabric rolls, multiple rolled canvases, metal profiles.
• Long lengths over 1m — the 4mm wall resists bending and flex in transit.
• Pallet and courier networks — repeated handling, stacking and conveyor pressure.
• High-value artwork — limited editions, gallery prints and commissioned pieces.
• Reusable cores — winding, storage and repeat internal use.

Same sizes, stronger wall

Every size in our extra heavy duty range is available in the 4mm ultra specification, from 240mm right up to 1046mm long, in 21mm, 38mm, 50mm, 76mm and 100mm diameters. Every tube ships with two plastic end caps — one fixed, one removable — in white as standard. If you'd prefer black end caps, just drop us an email at [email protected]. Volume discounts apply across the range.
