Seafab Metals Company
Seafab Metals Company – A trusted expert in lead metal fabrication
Seafab Metals Company is a trusted expert in lead metal fabrication. With a 90-year history of excellence in the lead industry, we deliver precision lead products to our customers in the construction lead fabrication and nuclear shielding industries.
Seafab Metals supplies precision lead metal materials that serve construction, medical, nuclear storage, and energy industry needs. Seafab Metals is compliant with current requirements by the nuclear regulatory standard ASME NQA‑1, the only quality program endorsed by the Nuclear Regulatory Commission.
Our safety achievements span decades, and we recently achieved 19 years without a lost-time accident. Customers know they can count on us to deliver exacting products that meet customer specifications.
The Casa Grande, Arizona, plant manufactures a variety of precision products, including nuclear shielding for waste containment, construction lead fabrication products and lead anodes for electrowinning. Our plants in Casa Grande and Vancouver, Washington, together annually deliver 30,000 tons of lead to customers across the U.S.
Seafab Metals is compliant with current requirements by the nuclear regulatory standard ASME NQA‑1, the only quality program endorsed by the Nuclear Regulatory Commission.
Seafab Metals has provided nuclear shielding technology since the days of the Manhattan project in the 1940s. Today, our facility manufactures ultra-high integrity lead castings for spent nuclear materials and related components. Continuous lead pours of up to 500,000 pounds are possible within our facilities.
Our commitment to quality and customer service drives innovation. We have been instrumental in bringing innovative materials and manufacturing methods to the nuclear industry. For example, Seafab Metals was the first to successfully apply calcium lead alloys as a solution to the creep-related dimensional stability problems in high energy calorimeters and radiation oncology focusing devices.
Lead and lead alloys have a long history as the material of choice in electrowinning and electro deposition. Seafab Metals is the industry leader in the production of lead anodes for these applications with our combination of metallurgical expertise and processing control that’s critical to product quality.
Seafab Metals manufactures anode sheets and shaped anodes for electrowinning and electro deposition, lead-calcium-tin plates for Copper SXEW anodes, and lead silver anode blades for zinc electrowinning. We also fabricate coextruded electrostatic precipitator anodes, providing the industry with a unique product solution that combines the strength of a high tensile core wire with the corrosion resistance and economy of an outer lead sheath.
