Ballast steel shot refers to steel spheres used for counterweights or ballast. Unlike abrasive steel shot used for blasting, ballast steel shot focuses on bulk density, flowability, rust prevention, and particle size combination.

Key info

1. Uses (Ballast / Counterweight)

- Yacht and wake boat ballast

- Dumbbells and barbells

- Construction machinery and crane counterweights

- Concrete weighting, radiation shielding walls, refractory products

- Toys and equipment balancing

2. Features

- Spherical steel particles with good flowability, can fill cavities

- Bulk density usually 4.2‑4.5 t/m³, cheaper and eco-friendly alternative to lead

- Can be mixed sizes to improve packing density

- Available in carbon steel or stainless steel for corrosion resistance in marine environments

- No SAE hardness standard needed, lower cost than blasting steel shot

3. Common sizes

Usually 1-8mm, often mixed grades (e.g., 2-5mm, 3-6mm), rarely blasting S series (S170/S330)

4. Main importing countries

- USA boats, gym equipment, largest ballast shot market

- Canada, Australia ships and machinery counterweights

- Europe (Germany, Netherlands, Poland) machinery, concrete weighting, gym equipment

- Russia machinery and ship counterweights

- Southeast Asia (Thailand, Malaysia) gym equipment and small machinery weights

Distinction

- Cast steel shot for blasting (SAE standard)

- Ballast steel shot for weighting (not for blasting)

Ballast steel shot is high-density spherical steel particles for counter-weight & ballast application. Good flowability, non-toxic alternative to lead. Mixed particle sizes available, suitable for marine boat ballast, gym equipment, machinery counterweight, heavy-duty concrete.
