Lowering energy costs starts by reducing consumption and eliminating waste, and our team at National Custom Hollow Metal is here to help!
TrustShield Lead-Lined Doors and Frames offer superior protection from gamma radiation!

Nuclear medicine is a powerful weapon in the ongoing battle against cancer and other serious illnesses, and early detection is the key to the best clinical outcomes! State-of-the-art tools such as CT Scans, MRIs, and X-rays are a noninvasive way for physicians and diagnosticians to examine tissues and internal organs before they operate, and radiation therapy is an aggressive form of treatment that doesn’t require patients to go “under the knife” at all! The short-term risks of exposing patients to gamma radiation are outweighed by the long-term health benefits of early diagnosis and treatment, but it’s crucial to protect the technicians who use the diagnostic equipment on a daily basis!
