MarShield Lead brick shielding provides the best choice for construction where temporary, permanent shields or storage areas are required, offering you the flexibility in your design and construction choices.
Lead Bricks are ideal for adding additional shielding to existing rooms and can be used in new construction as a method to reduce wall or ceiling thickness to achieve space savings. Cast from 99.94% pure virgin high quality lead as a standard or when more hardness in the bricks is required antimony is added. Our bricks are relatively smooth, clean and have a non-porous surface.
Lead bricks can be used for walls, coves, glove-boxes, hot cells or partitions, the transportation of radioactive materials, and nuclear shielding or simply as ballast weight. Bricks are available in a wide range of sizes, thicknesses and shapes to suit your application. They are commonly used for shielding when sheet lead is impractical or not available in sizes or thicknesses you may require. Straight or interlocking styles are available from our stock.

Since Sheet Lead can easily be shaped with little effort at ambient temperatures without the need for periodic softening or annealing it does not work harden. It therefore can be readily manipulated with standard hand tools without the risk of fracture.
As with most other commodities, sheet lead is usually sold by the pound and is available in rolled or sheet form.
