Iron and Steel

Increase Supply Chain Resilience with CDOT Code Across the Entire Chain

Iron and steel processing and transportation require item-level end-to-end traceability to ensure quality, efficiency, compliance, and customer satisfaction. CDOT codes achieves impeccable read rates from semi-finished billets during extremely high-temperature hot rolling stages.

Subsequently, during the cooling phases, CDOT's digital ID perseveres, maintaining its identity with a minimum of 100% read rates, even in the presence of challenges such as oxide formation (scaling).
