Electronic Galvanized Steel Coil

Electrogalvanized (cold galvanized)

Electrochemical galvanized layer of steel parts, anti-rust substrate, smooth surface

The process is simple

Pre-treatment → galvanizing → post-treatment, the coating thickness is accurate and controllable

Environmental protection mainstream

Cyanide-free technology, can make color zinc/black zinc, adapt to different appearance needs

The plating layer has strong adhesion, can be bent and stamped, and is suitable for the processing of precision parts and thin-walled parts.

Five. It is suitable for hardware/ home appliances/ automobile/ building accessories, and rust prevention is preferred for conventional atmospheric environment.

Distinguish between hot-dip galvanizing: the low-temperature process does not damage the substrate, and the rust resistance is slightly weak, which is not suitable for heavy corrosion environment.

Parameter Category	Parameter Name	General Range/Standard Requirement	Remarks & Explanations
Basic Process Parameters	Coating Thickness	5-20μm (Customizable)	5-10μm for precision parts, 10-15μm for regular parts
