Description
Reinforcing bar, or rebar, is shipped in bundled lengths breakbulk for construction. At around 0.30 m3/t the bundles stow fairly tight and are deadweight-limited. Manufactured steel outside the bulk regime, its care is about securing the long bundles, spreading weight and limiting rust.
Stowage & loading
Bundles are loaded by crane and stowed fore-and-aft on dunnage, blocked and lashed so the long, heavy units cannot work loose or shift. Dunnage spreads the load, and the stow is built so bundles are not crushed or distorted under the weight above.
Hazards & handling
The hazards are physical: long heavy bundles that can shift and roll if poorly secured, broken banding releasing loose bars, and sharp ends. Rust and wet damage are the commercial concern, so condition is surveyed and any oxidation or damaged banding noted on the receipts.
Carriage & discharge
The stow is kept secure and dry as far as practicable to limit rust, with lashings and banding checked through the voyage. Discharge is by crane; loose or distorted bundles are handled with care, and the delivered condition is recorded against the receipts.
Key hazards
- Long heavy bundles shifting or rolling if poorly secured
- Broken banding releasing loose bars, and sharp ends
- Rust and wet damage driving condition claims
Loading precautions
- Stow fore-and-aft on dunnage, blocked and lashed against movement
- Build the stow so bundles are not crushed or distorted
- Survey and record condition, rust and banding integrity
Stowage factors are indicative and vary with grade, origin, moisture and packing. Always verify against the shipper's cargo declaration and the applicable IMSBC Code schedule before fixing or loading. This is general information, not professional or safety advice.
