Lead Coil Lead Sheet
Absolute protection: density up to 11.34g/cm³, X/γ-ray shielding rate> 99% (especially good at high-energy rays above 300kV), lead equivalent accurate 1:1.
Ultra-thin and space-saving: 1-3mm thickness can meet the protection requirements, greatly saving the effective building area.
Flexible and easy to construct: can be bent and cut, fit complex structures (pipeline/equipment wrapping), support welding and sealing without leakage.
Stable and durable: corrosion-resistant, non-aging, service life of more than 30 years, maintenance cost close to zero.
High cost performance: low unit protection cost, 100% recyclable waste lead
Lead coils and lead plates are ultra-high-density protective materials rolled from electrolytic lead with a purity of ≥99.99%. With an absolute density advantage of 11.34g/cm³ and the physical properties of atomic number 82, they have become the industry gold standard for shielding high-energy X/γ rays and neutron flows. They are especially suitable for scenarios such as nuclear industry and medical radiotherapy that have extremely strict requirements on space efficiency and protection level.
1. Core product features
Ultimate protection performance
Full spectrum coverage: The shielding rate of 10keV-10MeV rays (including 6-15MV high-energy γ rays for medical linear accelerators) is >99%, and 1mm thickness is equivalent to 1mmPb lead.
Neutron protection extension: Neutron radiation can be efficiently slowed down through the composite cadmium layer (key application in nuclear reactors).
Morphological adaptation advantages
Lead plate (rigidity): high flatness (±0.1mm), suitable for planar structures such as walls and protective doors, and thickness 1-50mm can be customized.
Lead coil (flexible): bendable and winding (minimum curvature radius ≥ 5 times thickness), specially used for pipes, equipment wrapping and curved buildings (such as curved CT rooms), conventional thickness 0.5-5mm.
Hundred-year durability
Acid and alkali corrosion resistance (epoxy resin can be plated on the surface), stable performance at -50℃~150℃, service life > 50 years.
100% recycling and reuse, long-term cost is lower than composite materials.
2. Core application scenarios
Medical field
Rigid lead plate: radiotherapy room wall (2-3mm), CT machine protective fence (sealed with lead tape at seams).
Flexible lead coil: C-arm wrapping of angiography machine, mobile lead screen skeleton cladding (1.5mm coil).
Nuclear industry field
Lead lining of nuclear waste container (50mm composite plate), reactor neutron moderator (lead-cadmium composite plate).
Hot chamber observation window (step-jointed lead glass + lead plate), spent fuel transport channel (lead coil wrapped weld).
Industrial and civil
Industrial flaw detection room shield (3-10mm lead plate), radon-proof basement wall (0.5-1mm lead coil attached).
Data center electromagnetic shielding layer (ceiling lead plate ceiling), scientific research laboratory beam line protection (99.995% high purity lead).
