Frequently Asked Questions
Q: What are the primary applications of these steel coils?
They are widely used in manufacturing printer chassis, automotive seat frames, and consumer electronics that require effective EMI shielding.
Q: How is the coating thickness controlled?
The coating thickness is precisely managed via current monitoring, maintaining a tight tolerance of ±0.5 g/m².
Q: What alloy coating options are available?
We offer Zn-Ni (10–15% Ni) or Zn-Fe (0.3–0.6% Fe) coatings, which provide up to 3 times the salt spray resistance compared to standard options.
Q: What surface finishes can I choose from?
You can select either a bright finish (Ra 0.4–0.7 μm) or a matt finish (Ra 1.2–1.8 μm) based on your decorative or functional requirements.
Q: Why are these steel coils suitable for consumer electronics?
They offer excellent EMI shielding properties and high surface quality, which are crucial for protecting sensitive electronic components.
