Can DX51D coil undergo subsequent processing such as spraying and printing?
A: Yes. Its smooth surface and stable chemical composition make it well-suited for subsequent surface treatments such as spraying and printing, improving both appearance and protection.
What is the core difference between DX51D+Z275 and DX51D+Z150?
A: The core difference is the zinc layer weight. Z275 represents a double-sided zinc layer weight of 275g/㎡, while Z150 represents 150g/㎡. Z275 offers superior corrosion resistance, making it suitable for harsher environments.
What are the automotive applications of DX51D coil?
A: It can be used for truck and trailer body panels, and also as auxiliary components in non-load-bearing automotive structures, utilizing its anti-friction, impact-resistant, and corrosion-resistant properties to ensure its performance.
What causes zinc particle defects in DX51D coil?
A: The formation of zinc particles is often caused by unstable zinc bath temperature, excessive impurities in the zinc bath, or improper air knife pressure adjustment during the galvanizing process, leading to uneven zinc adhesion.
How to test the zinc layer thickness of a DX51D coil?
A: It can be measured directly using a professional coating thickness gauge, or it can be calculated based on the weight of the zinc layer. That is, by measuring the weight of the zinc layer per unit area and combining this with the density of zinc, the thickness can be calculated backwards.
