While many types of lead are not as commonly used as before, sheet lead is still an essential material in radiation shielding, construction, soundproofing, linings for vessels or tanks, and other types of manufacturing and fabrication.
In Construction and Roofing
Lead sheets can be sold in squares, or it can be rolled. In most types of construction applications, squares that weigh from two and a half to four pounds each are the most common option, with the squares measuring 30 inches or 36 inches square.
For construction types of projects, such as the protection of x-ray and imaging rooms or in areas where radiation is in use, the sheet lead is typically attached to drywall (gypsum) or attached to the plywood at the manufacturer. This ensures that the sheet stays in the correct position and does not fold or slump over time. Additionally, with the use of the plywood or gypsum lining, there is a complete edge to edge match of the lead, ensuring full protection and coverage for radiation protection.
Specialized manufacturers of lead products have their own rollers that can produce specific sizes of lead sheet. The top manufacturers offer custom made equipment capable of rolling sheet or plate that is as thin as 0.015 inches to up to 5 inches thick, and in widths of up to 110 inches and lengths of 25 feet.
Other Uses
Specialized types of sheet lead can also be used in the manufacturing of protective aprons and shields for those working in areas of radiation. In this type of application, the lead is fully covered, typically with cloth material, and can be held in place like on the body or simply draped over the area to be protected.
These types of sheet lead products need to be lightweight for use, so the lead is rolled thin. Different alloys can be used with lead to add to the ability of this type of material to be used for these applications.
