HBIS Zhangxuan Technology has successfully developed Zinc-Aluminum-Magnesium (Zn-Al-Mg) coated products, with five specifications now meeting engineering requirements for performance and surface quality.

In line with the latest Technical Code for Ecological-Grid Structures, these products feature Zn-Al-Mg alloy coatings combined with an eco-friendly inorganic protective layer, delivering excellent resistance to corrosion from acids, alkalis, and salt spray.

Compared with conventional products, their service life is extended by approximately 10 years. The products are now in stable production and have become a recognized brand in North China, with strong market potential across infrastructure and environmental projects.
