The marine sector of the defense industry has long relied on lead ballasts to achieve stability of their vessels, and on zinc and aluminum marine anodes to protect the vessel’s hull against corrosion. The high density and corrosion resistance of lead makes it a choice metal for ballasts in defense vessels, and ships in general, providing the weight required to ensure the vessel’s stability. When faced with the challenge of storing radioactive materials or protecting against gamma radiation exposure, lead sheet or cadmium sheet are both widely used in the defense industry. When greater thickness is required, lead blocks may be a better alternative. These blocks are suitable for temporary structures as well as permanent installations.
Utility sectors have long relied on quality lead products for tasks such as transporting wastewater, and protecting underground electrical cables and electrostatic precipitation systems. Given the diverse sectors within the utility industry, these lead tubes must be customizable for a multitude of unique needs. Bar solder must also be manufactured with precise variation in composition for differing projects. Lead and tin are common choice metals, due to their optimal balance of a low melting point and malleability, in either pure bars or in a spectrum of alloy compositions. Lead is also used to thread pole-line hardware preventing the potential cracking of insulators when they are installed.
Lead is known for being a principle material for gamma ray shielding, a need inherent to the nuclear industry. Lead is critical in protecting against radiation, which is present in both the nuclear and nuclear medicine industries. Depending on the strength of the energy exposure, thinner lead sheets or sheets of other metals such as cadmium or tin might be sufficient. Where the use of lead sheet is impractical, lead bricks and blocks provide a more versatile alternative. When more specialized services are needed, such as lead filling, lead lining, lead burning, and lead lamination to various surfaces, it is imperative to recruit a highly experienced and qualified team of professionals.
Like the nuclear industry, research labs that work with radioactive materials frequently depend on lead products and services for containment of radioactive materials and proper shielding. Radioactive isotope containers are one possible solution, as they come ready to receive and contain such materials. Alternately, it may be necessary to apply lead lining to cabinets, compartments, tanks, or surfaces that lack sufficient protection. Other customizable forms of shielding include lead, cadmium, and tin sheets, or lead castles which are modifiable based on containment needs. For the maximum x-ray/gamma protection for medical research labs, lead blocks, cast lead, and extruded bricks offer the strongest shielding.
