Our Numbered Lead Seals are precision-crafted sealing solutions designed for secure and tamper-evident applications. Made from pure lead with a polished finish, these seals come in both round and 15mm x 15mm square shapes with a thickness of 5-10mm. Each seal is individually numbered for traceability, making them ideal for high-security environments. Commonly used by coal companies, railways, electric utilities, and power corporations, these lead seals are packed in boxes of 100 pieces for easy handling and distribution.
