Lead Sheet/Lead Plate

Kolga’s lead sheet/plate is made from 99.9% pure lead which is melted, cast, then run through a high pressure rolling mill. Multiple passes under a tempered steel roller ensures consistent sheet/plate thickness (within +/_ .007 of requested thickness)

Custom sizes and thicknesses available for both lead sheets and lead plates. Lead plate thicknesses start at 3/16” up to 4”. Custom machined shapes are available in addition to squares and rectangles.


Kolga offers extruded lead products with shape, length, and width to customer specification. Our hydraulic pressure extrusion can produce lead extrusions from 1/4” to 4” in diameter. This allows Kolga to produce wire, bars, rods, and custom shapes all to customer specification.
