Tamper-evident Tinplate steel fixed length flat security metal strap ball seal for truck trailer

Description:

Our Metal Strap Seal (Ball Head Type) is a high-security, single-use tamper-evident seal engineered for cargo and asset protection. Crafted from robust galvanized steel or stainless steel, it features a fixed-length metal strap with a precision-engineered ball-head locking mechanism. The flat metal strap inserts into the ball-head housing, where an internal spring or wedge mechanism securely clamps it in place. Once locked, it can only be removed by cutting, leaving clear evidence of tampering.
Supports laser/embossed printing of serial numbers, company logos, barcodes, or custom text for full traceability. Meets ISO 17712 standards for indicative security seals, making it suitable for international shipping and logistics.

1Made from corrosion-resistant metals (galvanized steel/stainless steel), it withstands extreme weather, UV exposure, and physical impact—far outperforming plastic seals in harsh environments.
2.Any unauthorized attempt to open the seal results in visible damage (e.g., broken strap or deformed ball head), ensuring immediate detection of tampering.
3.The self-locking design allows quick application by hand: insert the strap into the ball head until it clicks into place—no tools required for sealing.
4.Single-use design eliminates rekeying or maintenance costs. Customizable marking options enable full asset tracking and accountability across supply chains.
