Description
Billets are semi-finished square steel sections shipped breakbulk for re-rolling into bars and rod. At around 0.22 m3/t they stow tight and are strongly deadweight-limited. Manufactured steel outside the bulk regime, their care concerns stowage, securing and protection from rust.
Stowage & loading
Billets are loaded by crane or magnet in bundles or loose and stowed on dunnage that spreads the concentrated weight over the tank top. They are blocked and secured to prevent movement, with the loading sequence planned so the structure is not overstressed.
Hazards & handling
The hazards are physical: heavy units, the risk of shifting and rolling if loose and unsecured, and sharp ends. Rust and wet damage are the commercial concerns, so condition is surveyed before loading and any oxidation recorded on the mate's receipts.
Carriage & discharge
The stow is kept secure and dry as far as practicable to limit rust, with lashings checked through the voyage. Discharge is by crane or magnet; dunnage and securing are cleared and the delivered condition recorded against the receipts.
Key hazards
- Heavy concentrated weight on the tank top
- Shifting or rolling if loose and unsecured
- Rust and wet damage driving condition claims
Loading precautions
- Stow on dunnage to spread the concentrated weight
- Block and secure bundles and loose billets against movement
- Survey and record condition and any rust before loading
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.
