G40 DX51D+Z Hot Dipped Galvanized Steel Strip 0.12mm × 60mm for Vending Machine and Appliance Components

１．Product Overview

G40 hot dipped galvanized steel strip is manufactured from DX51D+Z steel substrate and coated with a zinc layer through a continuous hot-dip galvanizing process. The combination of 90g/m² zinc coating and chromate passivation treatment provides corrosion protection for indoor and semi-exposed applications.

The 0.12mm × 60mm specification is widely used for vending machine components, appliance housings, cabinets, vehicle brackets, steel vessels, and light-gauge fabricated parts where dimensional consistency and surface quality are required.

２．Technical Solution

The steel strip is continuously galvanized to form a metallurgical bond between the zinc coating and the steel substrate. The zinc layer provides sacrificial corrosion protection while maintaining good forming performance.

Chromate passivation treatment improves resistance to white rust during storage and transportation. The regular spangle finish offers a traditional galvanized appearance suitable for industrial manufacturing applications.
