Lead

Lead is a dense, soft metal that is easily formed and offers excellent resistance to corrosion, radiation, and vibration. We stock lead sheet in a range of thicknesses for radiation shielding, sound deadening, chemical tank lining, and vibration dampening applications. Appropriate safety precautions should be observed when handling lead products.
