What Mayco Industries does

Mayco Industries, founded in 1938 and headquartered in Birmingham, Alabama, is the largest and most diversified manufacturer of lead-based products in the United States. The company operates three manufacturing plants (Birmingham, AL and Granite City, IL as core lead-fabrication sites, plus California through affiliated Santa Rosa Lead Products) and five distribution centers spanning the West Coast, Southeast, and Canadian channel via partner Ultraray Group Inc. It runs one of the largest lead alloy rolling mills in North America and one of only three remaining shot towers in the U.S., supporting processes that span casting, rolling, machining, extruding, and coating.

Its product portfolio is organized into five use-case segments: roofing and plumbing (flashings, sheet lead, solder, lead wool), radiation shielding (lead sheet and plate, interlocking bricks, lead-lined gypsum and plywood, lead vaults, custom machined parts), ballast and counterweights (bridge weights, custom pours up to 300,000 lbs, shot and stock ballast), ammunition components (lead shot under the 1879 Lawrence Brand and West Coast Magnum sub-brands, bullet alloys, bullet wire, lead billets), and specialty products (alloys, anodes, babbitt, extruded bar/pipe/wire, gaskets, castings, acoustic lead). Customers include the U.S. Departments of Defense and Energy, healthcare and radiology facilities, bridge and marine construction contractors, ammunition manufacturers and reloaders, and OEMs across aerospace and industrial machinery.

Revenue is generated through direct enterprise sales with quote-based custom fabrication (pricing tied to alloy, size, thickness, and volume), e-commerce through dedicated brand storefronts for consumer ammunition, and wholesale through qualified resellers. Stock items typically ship in 24-48 hours; custom work is project-priced with engineering support from design through delivery. The business is privately held with no parent company or institutional investor disclosed, and certifications include ISO 9001:2025.
