They provide higher physical security than plastic seals and meet ISO 17712 standards for international shipping.<\/p>\n<h4>Are metal seals stronger than plastic seals?<\/h4>\n<p>Yes, metal seals have breaking loads of 500-1,500kg compared to 15-80kg for plastic seals. Metal seals are used when physical strength is required, while plastic seals provide tamper evidence for lighter applications.<\/p>\n<h4>Can metal seals be customized?<\/h4>\n<p>Yes, we offer laser-etched logo, sequential numbering, barcode, and QR code on metal seals. Custom colors (anodized) and packaging are available. MOQ for custom metal seals is typically 1,000 pieces.<\/p>\n<h4>What tools are needed to remove metal seals?<\/h4>\n<p>Metal seals require bolt cutters, cable cutters, or specialized seal removal tools. They cannot be removed by hand, ensuring high-level tamper evidence.<\/p>\n<p><script type=\"application\/ld+json\">{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What are metal security seals used for?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"High-security applications: shipping containers, valves, pipelines, industrial equipment, hazardous materials.\"}}, {\"@type\": \"Question\", \"name\": \"Are metal seals stronger than plastic?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes, 500-1,500kg breaking load vs 15-80kg for plastic seals.\"}}, {\"@type\": \"Question\", \"name\": \"Can metal seals be customized?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes, laser-etched logo, numbering, barcode.
