Lead Shielding Products
Lead Lined Plywood
Lead lined plywood is generally used where a lead thickness in excess of 1/8″ but less than 3/4″ is required. Lead plywood panels can be fabricated in any width less than 48 inches and lengths less than 96 inches. Sizes should be based on stud spacing and panel weights. Each lead lined plywood panel should be sized to fully sustain its own weight without requiring intermediate fastening between joints. Lead plywood can be fire rated and is available in any grade and thickness
El Dorado offers full design and installation services for any lead plywood systems for radiation shielding including PET/CT shielding.
Lead Lined Drywall
Radiation shielding accessories for installation include sheet lead for backing and shielding of cut-outs for electrical, plumbing, medical gas, or other penetrations as well as corners with lead discs for screw penetrations. Lead discs may not be required as per NCRP 147.
El Dorado Metals offers a wide range of radiation shielding design services which include lead brick wall and ceiling systems complete with structural steel supports when needed. We have crews trained in the safe and quality installation of lead brick and lead plate and the associated steel structures that often are required.
Interlocking lead bricks are excellent for adding additional lead shielding to existing therapy vaults or treatment rooms as well as in new construction where available space is an issue. Lead brick can be installed in walls and ceilings where access is limited or difficult.
Our lead bricks are available in 3/4″, 1″, 1 1/2″ and 2″ thicknesses. Each lead brick features a tongue and groove design that eliminates streaming at the joints. Lead spec must be a minimum of QQL-171 Grade B.
Lead Sheet and Plate is available in chemical, copper bearing, and a variety of antimonial alloys.
Sizes available are up to 96″ Wide x 300″ OAL, with minimum thickness of .032″ up to 3″ available. All products conform to commercial standards of ASTM-B29; B-749; Federal QQ-L-201f; and QQ-L-171e. Required specifications must be defined at time of order for proper laboratory certification. All lead sheet and plate are protective wrapped, and banded prior to shipping.
El Dorado’s X-Ray glass (also known as leaded glass or radiation shielding glass) is manufactured with high quality material and has excellent purity and visibility characteristics. We offer our leaded x-ray glass in sizes up to 48″ x 96″. Our X-Ray glass can be cut to suit your radiation shielding needs for any job of any size.
Lead Lined Hollow Metal Door Frames
El Dorado’s lead lined door frames are manufactured from cold rolled 16 gauge steel. 14 gauge and 12 gauge lead lined door frames are available upon request. We offer either fully welded frames or knock-down frames although knock-down door frames are not recommended for use with pivot hinges. Lead lined door frames shall be suitably reinforced for closers, brackets and all other surface applied hardware. Drilling and tapping of surface hardware is typically done in the field by the installer. Our lead lined door frames are painted with a coat of rust inhibiting primer paint prior to delivery.
Lead Lined Hollow Metal Window Frames
Two Piece Slip Frames
With El Dorado two-piece slip frames, any existing rough opening can be wrapped with a lead line welded window frame that is very close in appearance to a borrowed light frame. Frames are made standard with a single rabbet and removable stop and, unlike typical telescoping view frames, are available with mullions. Frames are ordered from El Dorado using actual glass size. To calculate the rough opening necessary from the actual glass size, add 1 ¾” to the width and ¾” to the height of the glass. To calculate the overall frame dimensions from the actual glass size, add 4 ¼” to the width and 4 ¼” to the height of the glass.
Telescoping control window frames are supplied fully lead lined with an integral all purpose telescoping section to accommodate all types of wall construction. Frames are designed to fit walls ranging from 4 inches to 6 ¼ inches thick. The standard 2 inch face x ½ inch deep face return is aesthetically pleasing and is constructed of 16 gauge steel with corners fully welded and ground smooth. Frames are ordered from El Dorado using actual glass size. To calculate the rough opening necessary from the actual glass size, add 1 ½” to the width and 1 ½” to the height of the glass. To calculate the overall frame dimensions from the actual glass size, add 4 ¼” to the width and 4 ¼” to the height of the glass.
