Shandong Rigang Supply Chain Management Co.,Ltd. Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetics and anti-rust effects. The main method used now is hot-dip galvanizing.
The production process of hot-dip galvanized sheet mainly includes: raw sheet preparation → pre-plating treatment → hot-dip galvanizing → post-plating treatment → finished product inspection, etc. According to the habit, it is often based on the pre-plating treatment method.

Hot-dip galvanized coils can be divided into hot-rolled galvanized coils and cold-rolled hot-dip galvanized coils, which are mainly used in construction, home appliances, automobiles, containers, transportation and household industries. Especially steel structure construction, automobile manufacturing, steel silo manufacturing and other industries. Their main features are: strong corrosion resistance, good surface quality, conducive to deep processing, economical and practical, etc.
Galvanized coil factory direct sales, complete models, sufficient inventory, welcome to inquire, honest management, large quantity and high price, factory direct supply, spot supply welcome your consultation, professional management of automotive steel, galvanized coil, hot-dip coil, Sufficient stock of various models.
Zhengde hot-dip galvanized strip steel is produced with hot-rolled strip steel as the substrate through pickling, cold rolling, heating reduction, galvanizing and other technological processes. Its products can fully meet the international leading standards and can be obtained in the construction industry. A large number of applications can also be used in industries such as automobiles, railway locomotive manufacturing, warehouse board manufacturing, highway guardrails, etc. The surface spangles can be customized according to requirements.
Galvanized steel coils can be processed according to customer requirements: one-stop service such as processing Kaiping, galvanized steel coil slitting, cutting small plates, and door-to-door delivery. The galvanized steel coil slitting width is 5mm-1500mm, and the thickness is 0.1mm-3mm.
