Lead Ballast and Keel Weights

High-density lead ballast and keel weights designed to provide controlled mass and stability in marine and industrial applications.



Key Features and Benefits




  • High-density lead ballast blocks – provide substantial mass within compact component dimensions




  • Custom cast ballast shapes – support integration within keel structures or equipment frames




  • Precision machining capability – allows ballast weights to match installation requirements




  • Durable material construction – maintains structural integrity under long-term loading




  • Large-scale casting capability – supports production of ballast components in a wide range of sizes




  • Flexible manufacturing options – ballast weights can be cast or machined to match project specifications




Product Overview


Lead ballast and keel weights are used to provide stability in systems where controlled mass distribution is required. In marine applications, ballast is commonly incorporated into keel assemblies to help maintain vessel stability and improve handling characteristics.


Ballast weights are also used in industrial equipment and structural systems where additional mass is needed to stabilize structures or counterbalance loads. Lead’s high density allows significant ballast mass to be incorporated into relatively compact forms.


Ultraray manufactures lead ballast and keel weights using custom casting and machining processes. These components are produced to match the structural requirements of marine vessels, equipment assemblies, and specialized engineering projects.
