Frequently Asked Questions (FAQ)
What are the primary applications of these coated coils?
They are widely used in manufacturing automotive door inners, agricultural tillage tools, and warehouse racking systems.
How does the weldability of this coil benefit high-speed production?
With a low contact resistance of ≤1.5 mΩ, the coil enables efficient, high-speed robotic welding at rates up to 120 spots per minute.
Why is the low coating porosity important for phosphatability?
A coating porosity of less than 2% ensures uniform and consistent phosphate crystal growth (1.5–3.0 g/m²), which optimizes subsequent coating adhesion.
Are the post-treatment options environmentally friendly?
Yes, the post-treatment options are halogen-free, ensuring full compliance with international ELV and IMDS environmental protocols.
What makes this zinc-iron alloy coated coil stand out?
It offers a perfect balance of excellent weldability, superior phosphatability, and eco-friendly compliance, making it ideal for demanding industrial applications.
