Lead sheet roll is a flexible radiation shielding material manufactured with high-purity lead as the core raw material via precision rolling and composite coating processes. Combining superior radiation shielding performance and flexible constructability, it is extensively applied for complex structural radiation isolation in medical, nuclear and architectural fields, serving as a reliable all-round shielding solution.
Core Performance & Technical Parameters
High-Purity Radiation Shielding Capacity
Crafted with 99.99% high-purity lead and a standard density of 11.34g/cm³, the product features an adjustable lead equivalent ranging from 0.5mmPb to 3mmPb. It delivers over 95% shielding efficiency against X-rays and gamma rays, covering a wide energy spectrum from 10keV to 3MeV. It fully satisfies the professional protection requirements of CT rooms, radiotherapy departments, nuclear waste storage facilities and other high-standard radiation scenarios.
Each roll undergoes strict thickness inspection via X-ray fluorescence thickness gauges, with a controlled thickness deviation within ±0.05mm. The consistent material thickness ensures uniform radiation coverage and zero shielding blind spots for reliable overall protection.
Superior Flexibility & Processability
Boasting excellent ductility with a tensile strength of ≥10MPa and an elongation rate of ≥40%, the lead sheet roll allows curved bending with a minimum radius of 50mm. It can closely fit irregular structures such as pipe surfaces and wall corners, and supports various secondary processing including shearing, punching, argon arc welding and lead welding to adapt to diverse construction needs.
It adopts a convenient roll-type design with standard widths of 1m and 1.2m, standard lengths of 10–20m, and a single roll weight ranging from 1 to 3 tons. The compact roll structure facilitates easy transportation and storage, while keeping the on-site construction material loss rate below 5%.
Corrosion Resistance & Long Service Durability
Featuring a professional multi-layer composite protection structure, the product is coated with a 0.2–0.5mm thick PVC or epoxy resin outer layer, while the inner lead foil undergoes specialized anti-oxidation treatment. This endows the material with outstanding acid and alkali resistance, as well as moisture and mildew proof properties. It operates stably within a temperature range of -20℃ to 60℃ and maintains a stable shielding performance for over 20 years.
The fully enclosed coating structure effectively restrains lead powder leakage, with a leakage rate lower than 0.05μg/m³. Certified by RoHS and SGS, the product is non-toxic, harmless and eco-friendly, fully compliant with global occupational health and safety standards.
Economical & Efficient Construction Solution
Available in conventional thickness specifications from 1mm to 10mm, the lead sheet roll features an optimized lightweight design. Its weight per unit area is 10%–15% lower than traditional solid lead plates, significantly reducing the load-bearing pressure on building walls and supporting lightweight engineering construction.
The product adopts a dual fixing installation method combining lead glue bonding and mechanical fixation via keels and pressure plates. Overlapping sealing with lead tape (≥0.5mmPb lead equivalent) at all splicing joints eliminates radiation leakage gaps, improving overall construction efficiency by 30% compared with traditional processes.
