At Mayco, we build our Lead-Lined Plywood from our very own sheet lead. Which makes sense, considering we have no trouble meeting government specifications. (See below for details.)
We furnish our lead-lined plywood in 4′ x 8′ sheets, and we can make other sizes as you need them. For the installation, we recommend our Lead Angles.
Generally, your plywood’s thickness will depend on the level of shielding your project requires. And there’s no better defense against radiation than MayShielding.
Government specifications listed above are Federal Specification QQ-L-201 F and ASTM B 749-03 for lead that is laminated to ½”, 5/8”, ¾” or 1” fire resistant plywood.
