• An extensive range of materials and finishes are available to provide maximum design versatility while meeting the aesthetic and performance needs of any facility.

Shielding Information

• HMS Metal offers a variety of lead thickness. The lead thickness is determined by the intended application of the product and the determination of thickness is the responsibility of the purchaser. For frames and doors the lead sheet is applied to the inside of the skin of the door on the “pull” side. Ensuring the continuity of the lead lining in the frame and the wall is the responsibility of the frame installer.


• Our lead shielding is of a continuous sheet of lead as specified. The sheet lead will be unpierced, free of defects, laminations, scale blisters, cracks or penetration. The amount of shielding necessary in a door or frame should be equal to the shielding required in the wall in which it is to be installed in. The sheet lead shall be shaped to fit into the frame contour and inserted in the frame. All lead joints are welded together to insure continuity of shielding and to secure in place during transit and installation.

Hardware & Shielding
Hardware selection can be the toughest decision on the success of your installation process. The final hinge system has to be appropriately specified to handle the heavy weights that the sheet lead imposes on the door. Door hardware is usually specified and supplied by others. Hardware selection should ensure lead lining in its components are equal to the door and frame assembly. Necessary precautions are needed in the field when installing the hardware to prevent penetration of existing lead shielding in door and frame.

Site Storage and Protestion of Material
All materials must be thoroughly inspected upon receipt of goods. All discrepancies and/or damages shall be immediately noted and reported in writing to us and on the freight bill of lading when received. All materials received shall be properly stored on blocks or skids with adequate clearance from floor with a covering that will allow adequate circulation around product. Keep materials free from any contact of water, moisture, or dampness on a flat, dry level surface. The room should be properly ventilated to carry the dampness out of room. Also avoid any exposure to direct sunlight, extreme heat source, and humidity or excessive temperatures.

Doors Installation

• Do not start your installation in areas that still contain excessive moisture from wet plaster, or cement.


• Ventilation systems should be operational and functioning correctly.


• Allow doors to acclimatize to surroundings before actual installation.

During installation the frame should bet set plumb, square and level at the correct elevation. Ensure that the frame is adequately secured into the studded wall to properly support the door weight and size. Use a proper hinge system rated for door weight and size. We recommends the use of pivot or continuous type hinges for all applications. When butt hinges are to be specified and used they must be fully rated for the weight and size of the lead lined door. A minimum of three hinges should be used for doors up to 90″ in height. For every extra 30″ of door height add one more hinge or portion thereof. Be sure to follow all manufacturers’ recommendations and guidelines for locations and quantities, when different to above. Consult with the site physicist to insure proper shielding is maintained at each opening.

Frame Installation
It is critical that the frame be installed by an experienced person who can ensure it to be plumb and square in the available opening that is provided. The frame must be securely fastened into place within the studded wall prior to the receiving of the drywall. The lead lined wall must then be built into the frame to effectively provide a shielding overlap for the lead in the face and throat of the frame.

Order Information Required
When ordering a door and frame it is critical that all necessary information be supplied. We cannot be held responsible for insufficient or missing information. It is up to the purchaser to ensure that all necessary information is provided at time of quoting. When ordering frames for lead glass, please specify whether the width and height you provide are for the glass viewing area or the frame. E.g.: When specifying 12″ x 12″ the actual glass could be this size but not the viewing area. The frame can add a few inches all around and the glass sits inside of this frame. The 12″ x12″ can be taken as an inside frame size but is usually considered an outside frame size. A small sketch is usually the best clarification in ensuring there are no mistakes made.

Advantages of installing plywood/gypsum board with lead lining

• Provides effective floor-to-ceiling radiation protection
• Offers design flexibility for use in walls, floors, and ceilings
• Eliminates the risk of radiation leakage when properly installed
• Available in varying thicknesses to meet a wide range of shielding requirements

Cutouts & Penetrationd

• When installing lead lined plywood or drywall (lead lined sheetrock, lead lined gypsum), all cut outs, seams and penetrations will require sheet lead or lead plate to ensure continuous shielding throughout the room. Proper installation of additional lead wherever penetrations are created will eliminate potential leaks and ensure total protection.
• Additional sheet lead can be supplied to easily allow for the proper shielding of penetrations such as receptacles, light switches, ducts and telephone/data cables.

Providing Suffcient shielding from Different types of Radiation

• Different types of radiation are emitted with different levels of energy behind them, but all are caused by unstable atoms. The greater the energy of the radiation, the greater the level of shielding required to safely shield against it. When proper shielding is not provided, radiation can cause burns on the skin and at high levels, puts people at risk of radiation sickness.
• Alpha radiation (α) is comprised of very weak particles that are unable to travel more than a few centimeters when airborne and therefore requires little shielding. In fact, the outermost layer of human skin is actually enough to protect against this type of radiation.
• Beta radiation (β) particles can travel farther because of its small mass and requires more protection, such as heavy clothing or a thick piece of plastic, wood or aluminum. Certain beta radiation particles can penetrate and burn the skin.
• Gamma radiation (γ) consists of photon energy, not particles, and can travel far distances. Protection from gamma radiation requires the use of dense materials such as lead to provide effective radiation shielding. Gamma rays are biologically hazardous and can cause tissue, bone and organ damage if proper protection is not used during long periods of exposure.
• X-ray radiation are considerably stronger and have a longer wavelength than other types of radiation and requires thick, dense shielding, such as lead. Because prolonged x-ray radiation exposure can cause DNA mutations, it is classified as a carcinogen.

Impotant fator of determining Your Radiation Shielding Requirement

• Radiation shielding is available in varying degrees ranging from protective vests and leaded glass barriers to rooms constructed with lead lined drywall, doors and windows. High energy radiation applications and those involving nuclear power may also require the use of lead bricks for additional shielding protection.
• There are various lead shielding considerations including radiation type, equipment orientation, workload and occupancy but exposure time and distance are the most important in calculating the level of protection required for your application.
