Electro-Galvanized Carbon Steel Coils
Electro-galvanized carbon steel coils boast a smooth, clean surface free of zinc blooms, exhibiting a refined and delicate appearance. The coating is uniform and ultra-thin, with high dimensional accuracy and a straight, even shape. China manufacturers offer customized services.
The processing and customization capabilities of Chinese Electro-Galvanized Carbon Steel Coils manufacturers are reflected in four aspects: precise specifications, meticulous craftsmanship, comprehensive post-processing, and rapid response. This comprehensively meets the needs of high-end applications such as home appliances, electronics, and automotive interiors.
Core Customization Capabilities
Specification Customization: Supports thicknesses from 0.12-3.0mm, widths cut to order, zinc coating flexibly adjusted from 5-30g/㎡, and provides specialized materials such as deep-drawing (DC06E+Z), fingerprint-resistant (SECCN5), and chromium-free passivation. Minimum order quantity is as low as 5 tons.
Precision Machining: Equipped with leveling, slitting, and laser cutting equipment. Leveling accuracy ±0.5mm, slitting width tolerance ±0.1mm, bending radius up to 0.5 times the plate thickness, burr-free edges, and coating non-peeling.
Post-processing upgrades: Offers passivation, fingerprint resistance, rust-proofing oiling, and color coating processes; surface roughness Ra≤0.5μm; zinc coating adhesion reaches 5B level; suitable for precision spraying and welding requirements.
Technology and Service: Full-process quality traceability, combined with constant current pulse electroplating and other technologies to ensure performance; 7-10 day fast delivery, urgent orders shipped within 48 hours; one-on-one technical support provided.
Comparison Table of Electro-galvanized vs. Hot-dip Galvanized Carbon Steel Coils
|
Comparison Items: |
Electro-galvanized carbon steel coils (electrolytic galvanizing) |
Hot-dip galvanized carbon steel coil (hot-dip zinc plating) |
|
Production Process |
Electrolytic deposition method, room temperature electroplating |
High-temperature molten zinc immersion, direct galvanizing of hot-rolled/cold-rolled substrate |
|
Zinc Coating Thickness |
Thin, 5-30 g/m² per side |
Thick, 40-350g/m² per side, high zinc layer possible |
|
Surface Appearance |
Extremely smooth and delicate surface, no zinc spots, high aesthetic appeal |
Surface has zinc flowers, relatively rough, slightly less flat |
|
Dimensional Accuracy |
Small thickness tolerance, good sheet shape |
Tolerances are slightly larger, sheet shape slightly inferior to electro-galvanized |
|
Corrosion Resistance |
Generally suitable only for indoor/slightly corrosive environments |
Excellent, suitable for outdoor and highly corrosive environments |
|
Processing Performance |
Better stamping, welding, and painting performance |
Good bending and welding performance, high zinc layer is prone to zinc peeling |
|
Cost |
Higher cost |
Lower cost, higher cost-effectiveness |
|
Typical Applications |
Applications: Home appliances, chassis, automotive interiors, precision hardware |
