Product Advantages
Small dendrites space distance
With unique formula of the coating and control of coating thickness, the dendrite spacing of Yifashun galvalume steel is 10-15μm under electron microscopy, and the corrosion resistance of the product is excellent.
Coating cross-sectional structure - optical microstructure
The coating structure of Yifashun's products is a staggered skeleton, which has good density and can prevent the intrusion of rainwater and other corrosive media, and that is why the product has good corrosion resistance. If the coating structure is bamboo-like, which means the coating layer is not dense enough and the corrosion resistance can be poor.
Small-sized and uniform spangle
The stability of crystallization determines the size and uniformity of spangles. The spangles are precisely controlled under the combined effects of the steel strip temperature, zinc liquid temperature, surface roughness, post-plating cooling, and special coating formula. The diameter of the spangle of Yifashun's galvalume is controlled between 0.5-3mm, which means the spangles are small-sized and uniform, and the appearance effect is more stable.
Chromate/Passivation+AFP
We adopt double-coating and baking process for post-treatment, which means we first to passivate, dry and cool the sheets, next to apply AFP coating on the sheets and dry and cool. The AFP film is thicker and cured better, so the processing lubricity is relatively better.
