Galvanized Steel Sheet Coil HX180BD
Five irreplaceable core advantages
1. King of precision stamping – 0.1mm extremely narrow tolerance control
Using ultra-low carbon steel base (C≤0.008%) and patented annealing process, ultra-uniform plastic flow with △r value ≤1.5 is achieved, which completely solves the cracking and wrinkling problems of complex parts such as door hinges and motor housings.
2. Zinc-iron alloy coating – 10-year anti-corrosion guarantee
GA coating forms a dense Fe-Zn alloy layer, and the salt spray test is ≥720 hours without red rust, far exceeding the 480-hour standard of pure zinc coating (GI), which is suitable for high-humidity electrical components.
3. Laser welding friendliness – saving 20% of production line energy consumption
Low surface roughness (Ra 0.8-1.2μm) and homogeneous coating increase the laser welding speed to 12m/min (conventional plate 8m/min), reduce welding slag by 70%, and significantly reduce the manufacturing cost of battery pack shell.
4. Green environmental compliance – global access pass
Passed REACH SVHC 205 items and RoHS 2.0 certification, providing chromium-free passivation (ECP) options to meet the mandatory requirements of the EU/North America/China new energy vehicle supply chain.
5. Cost optimization of the entire process – $150 saved per ton of steel
Compared with ordinary cold-rolled plate + post-galvanizing process:
Omit the separate galvanizing process (cost↓$80/ton)
Material utilization rate increased by 8% (blanking optimization)
Reduced mold wear (hardness HV 50-55)
