Import Container Door Latches Metal Seals — Buy in Bulk from Supplier in China

Container door latches metal seals from Shandong Junchuang Lock Industrial Co., Ltd. are tin-plated flat metal security devices designed for tamper-evident closure of shipping containers, van trucks, and railway trucks. The seals use a tinplate steel body paired with galvanized steel wire, copper wire, nylon-coated wire, or stainless steel wire for the locking mechanism. Standard length is 217 mm, with custom lengths available on request, and each unit carries embossed consecutive sequential numbers for traceability and audit compliance.

The metal seals are manufactured from tinplate steel in its natural colour, offering corrosion resistance suitable for ocean shipping and long-haul logistics. Typical industry specifications for such seals include a breaking strength of 1,200 - 1,800 N (standard for container security), with wire diameters commonly ranging from 1.5 mm to 2.5 mm. The embossing process ensures sequential numbering remains legible throughout transit, and the design meets ISO 17712 standards for mechanical seals used in freight transport.

These seals are primarily used by logistics operators, shipping lines, and freight forwarders to secure containers against tampering during ocean and land transit. Buyers typically source in bulk, with standard packaging of 100 pieces per bag and 1,000 pieces per carton. The product is supplied from Dezhou, Shandong, and is compatible with 20-foot, 40-foot, and high-cube containers, as well as tank trucks and railway freight cars. Confirmation of exact wire material and length should be requested prior to bulk orders to ensure compatibility with existing hardware.
