0.1-0.5mm (about the thickness of A4 paper to credit card) galvanized steel coil is an ultra-thin metal material, which is galvanized on the surface of cold-rolled steel substrate by electroplating or hot-dip coating. It has both the strength of steel and the rust-proof ability of zinc layer, with an elongation of ≥35%, and can be used to process complex micro parts.

Frequently Asked Questions
▸ Q: Can it replace stainless steel?
A: It can replace SUS304 in electromagnetic shielding and cost-sensitive scenarios, reducing weight by 30% (corrosion resistance needs to be evaluated)
▸ Q: How to prevent ultra-thin plates from deformation?
A: It is recommended to use a magnetic spreader for loading, and the stamping speed is ≤15 times/minute
