Even though prolonged exposure to radiation is harmful to humans, X-Rays, CT Scans, and MRIs provide useful diagnostic information to physicians in a noninvasive format that justifies the risk for a short period of time. Radiation therapy is another highly effective weapon against cancer and other invasive health problems. Patients are only exposed to radiation for short periods of time, but the technicians who perform the procedures are particularly susceptible to some serious health problems if they don’t have a safe place to work.

National Custom Hollow Metal is proud to offer custom-built TrustShield doors and frames.All of our doors are custom built to your exact specifications, and shipped on your schedule. At NCHM, The Difference is Quality, and every product that we manufacture is subjected to a rigorous multi-point quality inspection before shipping, and they’re all built right here in the USA.

TrustShield Lead Lined doors are custom built with 16, 14 or 12 gauge galvanneal or 16, 14 or 12 gauge stainless steel construction with a continuous sheet of lead from 1/32″ thick up to 1/8″ thick, laminated to the door skin and a sheet of high density polystyrene. The lead sheet extends the full width and height of the door, with the thickness of the lead shielding to be equal to that of the adjacent wall. Lead lined doors can be built at 4′ 10 1/2″ x 12’0″ with 1/16″ lead and 4’10’/2″ x 8’0″ with 1/8″ lead, and all doors have continuous 14 gauge channels installed around the perimeter as reinforcement to ensure years of trouble-free service. Trustshield doors can be manufactured with UL or Warnock-Hersey fire resistance labeling up to 1-1/2 hours with maximum lead thickness of 3/32″.

All NCHM orders come with standard Quik Ship service, and we also offer expedited shipping. Our doors are carefully crated before shipping, and corrosion-resistant. All you have to do is occasionally rinse them with warm soapy water to maintain their factory-new appearance for decades!
