Frequently Asked Questions

What are metal security seals used for?

Metal security seals are used for high-security applications including shipping containers, valves, pipelines, industrial equipment, and hazardous materials. They provide higher physical security than plastic seals and meet ISO 17712 standards for international shipping.

Are metal seals stronger than plastic seals?

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.

Can metal seals be customized?

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.
