Materials Are Where Shielding Performance Is Decided
Every attenuation value in a shielding report assumes the installed material actually delivers its nominal properties — full-density lead without voids, borated products with the boron genuinely in them, thicknesses that match the drawing. Because MSA Projecta manufactures shielding doors for a living, we learned early that the only way to guarantee this is to source, process and quality-control materials in-house. That same supply chain is open to your project: contractors building bunkers, physicists upgrading existing walls, and institutions solving a local shielding problem can buy the exact materials we trust in our own products.
Photon Shielding — Lead Products
- Virgin lead sheets and plates conforming to ASTM B-29, supplied in project-specified thicknesses with maximum 3% thickness variation and defect-free surfaces
- Interlocking lead bricks and blocks for self-supporting walls, maze linings and local hot-spot reinforcement — the interlock geometry eliminates straight-line joints
- Cut-to-size pieces for penetration collars, duct chicanes, frame wrapping and detail work around conduits and services
Neutron Shielding — Borated Products
- Borated polyethylene (BPE) panels and blocks — hydrogen-rich moderation with minimum 5% boric oxide content per IAEA guidance, machinable on site to fit real geometry
- Borated paraffin composites — cast neutron shielding for cavities, retrofit pockets and irregular volumes where panel products cannot reach
- High-density concrete additives for projects solving shielding in the structure itself
Where These Materials Go
Typical supply projects include bunker wall and ceiling reinforcement after an energy upgrade, maze linings that bring an older vault to current requirements, shielding of HVAC and cable penetrations, door and frame refurbishments, cyclotron vault details, and research or industrial facilities buying certified materials for their own construction teams. We ship worldwide, with export documentation and packing engineered for dense cargo — lead punishes casual logistics, and we have long since stopped being casual about it.
Supply With Engineering Attached
What separates a materials partner from a metals trader is the engineering around the delivery. Tell us the problem — the machine, the energies, the wall, the measured hot spot — and we will confirm quantities and thicknesses against a calculation before anything ships, flag where a different material solves the problem cheaper, and provide installation guidance so the certified attenuation you paid for is the attenuation you get. Material certificates and traceability documentation accompany every delivery for your regulatory file.
Packing, Handling and Site Logistics
Shielding materials punish casual logistics: lead is dense enough to overload a pallet that looks half empty, soft enough to be damaged by careless strapping, and heavy enough to make site handling a safety topic in its own right. Our deliveries arrive on engineered packing with declared weights per package, lifting guidance, and quantities staged to match your installation sequence rather than one monolithic drop the site cannot move. For international projects, export documentation and customs classification are prepared with the shipment — and where your installation team wants a briefing on handling and joint detailing before the work starts, our engineers provide it as part of the supply.
