Sheet Lead
"The World's Largest Lead Rolling Mill" is currently located in MAYCO's Birmingham location.
Mayco invested in this piece of equipment to meet the growing demand from it's customers for
lead sheet, and it's own requirements for Mayco's growing Architectural lead shielding product
applications !MAYCO's lead sheet is ideal for building, industrial, waterproofing, and various shielding requirements including
x-ray radiation & nuclear shielding.
We roll our own lead sheet. Our capacity is the Nation's largest, including the largest lead rolling mill in the world.
Our rolled sheet lead is incorporated into our lead lined Gypsum Board and drywall products as well as our roofing products. We sell our sheet to numerous fabricators for their own applications.
This page includes detailed specifications for lead sheet composition, dimensions and other important properties. Obviously, Mayco has the product knowledge and the manufacturing capability to match your needs with the right thickness and composition of lead sheet for your product or project.
For Specifications relevant to CSI Section 13 4900 (Radiation Shielding) Click HereThe standard sheeting is rolled from 99.5% pure lead or better. Rolls are available from 6 inches to 8 ft. widths and up to 25 ft. lengths. Most other sizes are available upon request, along with our Plate, Brick, Circles and Special fabricated products. Sheet is also available as Lead Strips.
