Construction Lead Bricks

Engineered lead bricks for construction projects requiring high-density mass, structural ballast, vibration dampening, and custom heavy assemblies.



Key Features and Benefits




  • 99.5% Pure Lead (ASTM B29 / QQ-L-171E) – ensures consistent density and predictable weight performance for structural and ballast applications




  • Cast or Extruded Manufacturing Options – allows flexibility in tolerances, finish, and structural requirements




  • Custom Sizes and CNC Machining Available – enables precise integration into machinery bases, counterweights, vault builds, and engineered assemblies




  • Multiple Brick Profiles Available – choose from Flat (Straight), Chevron Interlocking, or Circular Interlocking styles to suit installation needs




  • Antimony Additions Available – increases hardness where structural rigidity is required




  • Optional Coatings (Paint, Powder Coat, Vinyl) – improves handling, corrosion resistance, and job site durability




  • Available in Small or Bulk Quantities – order from single units to full truckloads without production delay




Product Overview


Ultraray Metals manufactures construction-grade lead bricks designed for high-density applications across infrastructure, manufacturing, heavy equipment builds, and specialty construction projects.


Our lead bricks are produced from 99.5% pure lead or higher, with optional alloying to increase hardness where required. Available in flat, interlocking chevron, or circular interlocking profiles, these bricks are adaptable for both permanent and temporary installations.


Thanks to in-house CNC machining capabilities, we can manufacture custom dimensions and specialty profiles to meet project-specific requirements. Whether used for ballast, vibration isolation, shielding infrastructure builds, or weight distribution systems, our construction lead bricks deliver consistent density and performance.
