Product Overview
Ultraray Radiation Protection produces custom lead bricks for radiation shielding across medical construction, nuclear laboratories, barriers, booths, NDT testing facilities, and ballast applications. Manufactured to ASTM B29 and QQ-L-171E standards from 99.9% pure lead, our high-density lead bricks provide dependable radiation protection while remaining easy to install and reconfigure.
Lead bricks remain a practical choice for modular shielding due to their density, stackability, and adaptability. They can be easily adapted to existing structures for additional shielding capacity, and they suit both permanent and temporary structures thanks to their ease of construction and flexibility in design.
Available in Chevron, Flat, and Circular styles, lead bricks can be precision machined to any custom size or shape through Ultraray’s in-house CNC process. With warehouse stock on hand and CNC capacity for custom orders, Ultraray supports both small orders and full truckload quantities throughout Canada and the United States.
