How to Solve your Shielding Challenges with Sheet Lead Product Options

Sheet lead for Radiation Protection in laboratories, clinics, dental and medical application can be a challenge. Many contractors and architects face challenges due to space criteria and the weight of the shielding requirements. We provide Sheet lead in 12 different sizes and thicknesses from 1/32nd to 1/4" for all shielding requirements. In addition, any size sheet lead up to 1/8" can be supplied pre-attached, adhesive bonded to Drywall (sheetrock), Fire Rated Plywood and other supporting materials to assist in the ease of installation. For areas that require minimum panels to partition we have created our own prefinished lead lined panels called "Easy Shield Panels". These panels save time and achieve a finished look for already constructed areas without the chaos of construction. It is important to install to all regulation requirements with approved products. Sheet Lead must be manufactured from Pure Lead and meets ASTM B-29, B749 and Federal QQ L-201F, QQ-L171E standards. MarShield can assist with our in-house engineering services and physics shielding analysis where a solution is required.
