Frequently Asked Questions
Q: What are the primary applications for these steel coils?
They are widely used in printer chassis, automotive seat frames, and consumer electronics that require effective EMI shielding.
Q: How precise is the coating control during manufacturing?
The coating control achieves a precise thickness tolerance of ±0.5 g/m² through advanced current monitoring systems.
Q: What alloy coating options are available?
Options include Zn-Ni (10–15% Ni) or Zn-Fe (0.3–0.6% Fe) coatings, which provide up to 3 times the salt spray resistance of standard coatings.
Q: What surface finishes can be selected for different functional needs?
You can choose between a bright finish (Ra 0.4–0.7 μm) or a matt finish (Ra 1.2–1.8 μm) depending on decorative or functional specifications.
Q: Why are these coils recommended for consumer electronics?
They are highly suitable because they offer excellent EMI shielding properties combined with precise surface finishes and high wear resistance.
