They're built for shipping high-value, heavy or oversized contents where a thin-wall tube simply isn't strong enough — including blueprints, fabric rolls, steel rule, oversized prints, rolled canvas and industrial parts. ### When to choose extra heavy duty over standard - **Heavy contents** — rolled fabric, multiple posters, steel rule, large maps. - **Long tubes** — anything over 1m benefits from a 3mm wall to resist flex. - **High-value shipments** — framed prints, limited-edition artwork, signed posters. - **International postage** — extra handling means extra risk; the 3mm wall absorbs it. - **Industrial & trade use** — winding cores, construction plans, engineering drawings. ### Industrial & large cardboard tubes If you need an even thicker wall (up to 12mm), a larger diameter, or lengths up to 3 metres, our bespoke cardboard tubes (https://www.packagingpanda.co.uk/bespoke-cardboard-tubes.html) service manufactures custom industrial cardboard cores for fabric winding, concrete forming, paper conversion and bespoke industrial use. ### End caps & sealing Every extra heavy duty tube ships with two plastic end caps as standard — one fixed at the factory, one removable so you can insert your contents and seal the tube before postage. Caps come in white as standard — if you'd like black end caps, just email sales@packagingpanda.co.uk and we'll fit black. For high-value shipments we recommend running a strip of tape over each cap as additional security. ### Wholesale pricing Volume price breaks are built into the pricing table above. Buy a single pack to trial a size or order by the pallet for the lowest possible per-tube cost. See our full range of cardboard tubes (https://www.packagingpanda.co.uk/cardboard-tubes.html) for 1.5mm and 2mm wall alternatives, or our poster tubes (https://www.packagingpanda.co.uk/poster-tubes.html) for lighter contents. ## Extra heavy duty cardboard tube FAQs ### How much weight can a 3mm cardboard tube hold? A 3mm-wall cardboard tube can comfortably support several kilograms of axial load and resist significant lateral crush — far more than standard postal tubes. Exact load capacity depends on diameter and length; contact us for industrial winding-core applications. ### How do I cut a 3mm cardboard tube? A fine-tooth saw gives the cleanest cut on a 3mm wall. Mark the cut line all the way around, support the tube on a flat surface, and saw with light pressure to avoid tearing the inner layers. Sand the cut edge smooth if it needs to be reinserted into another tube. ### Are extra heavy duty tubes waterproof? The cardboard wall isn't waterproof on its own, but the 3mm thickness gives much better short-term water resistance than thin-wall tubes — especially in the postal network. For long-term outdoor use or wet environments we offer waterproof-lined bespoke tubes; ask on the bespoke enquiry form (https://www.packagingpanda.co.uk/bespoke-cardboard-tubes.html). ### Are 3mm cardboard tubes recyclable? Yes. The cardboard body is fully recyclable through standard kerbside paper and card collections. The plastic end caps can be removed and recycled separately at most household waste centres.
