Two-Tier 200L Drum Stacking at 2.4 Tonnes: Holding a Chemical Load on a ±2 mm Presswood Pallet Deck
A specialty chemical group shipping polyurethane, silicone and propylene glycol in 200 L drums and IBCs across regions asks one thing of the pallet under the load that a nailed wood pallet was never built for: hold roughly 2 to 2.4 tonnes across two drum tiers on a deck plane that stays flat. The arithmetic is plain: a filled 200 L steel drum runs about 250 to 300 kg, four drums to a layer, two layers, and a drum sits on a rolled chime ring with a concave bottom, so the mass travels through a narrow annular contact band. On a sawn board deck the plane is the sum of board crown, cup and thickness spread; under 2 to 2.4 tonnes the boards deflect between bearers, the plane tilts, and a tilting drum is a chime load and a leak path rather than a cosmetic complaint. Ampallet is a pressed wood pallet molded in one piece from recovered wood fibre and an MDI binder on a 1600 ton press, deck and reinforcement ribs and support feet as one body, deck flatness held to plus or minus 2 mm, and for this lane a 1140 x 1140 mm double-face reinforced build with a cross-base structure and a 15 mm particleboard strip, bolt assembled, rated 2.5 tonnes dynamic and 8 tonnes static. Limits are stated plainly: load is confirmed against the specification sheet for the actual drum count and stacking height, the double-face unit is a bolt-assembled configuration rather than a nestable single-face pallet, and a fumigation-free reading stays a destination rule and forwarder question.
