1. The same process in essence Hot-dip galvanized wire and hot-dip galvanized iron wire are actually different names for the same process, both referring to the protective layer formed by immersing iron wire in molten zinc at 450°C. Just like boiling noodles and lo mein are both noodle dishes in essence, they differ only in the perspective of expression:

. The thickness of the zinc coating is typically 30-60 micrometers

. The surface exhibits typical zinc flake crystallization patterns

. The processing temperature is controlled at 460±5℃

II. Differences in Rust Prevention Performance Despite using the same process, products of different specifications exhibit varying rust prevention capabilities:

. Wire diameter influence: 2mm thin wire has a more uniform zinc coating than 6mm thick wire

. Zinc purity: 99.995% high purity zinc ensures longer-lasting effect

. Post-treatment: Corrosion resistance increases by 50% after chromic acid passivation treatment

III. Usage Selection Guide: Make reasonable choices based on usage scenarios:

. Horticultural binding: Prefer fine specifications with good flexibility

. Building fence: suitable for thick zinc coating and coarse specifications

. Humid environment: It is recommended to choose products that have undergone passivation treatment

. Temporary use: ordinary galvanizing can meet the requirements
