In harsh environments, corrosive agents are one of the most serious damage factors for construction works. To overcome these factors, Ton Nam Kim has launched the high-end product line Zinmag® Color , which provides the optimal protection solution thanks to the Zinmag® substrate structure with 5-layer synergistic protection, combined with a high-quality paint system, helps protect the building from corrosion, ensuring long-term durability and aesthetics.

Zinmag® Color corrugated iron is the perfect combination of a high-grade coating system (SPE, SMP, PVDF) and Zinmag® Superior Anti-corrosion Coated Steel with 5 layers of corrosion resistance: Aluminum – Zinc – Magnesium – MgZn2 – FeZn, forming an extremely strong and sustainable surface and cutting edge protection solution. This is an ideal product for buildings in harsh environments, such as industrial, chemical, livestock, coastal areas, or areas affected by extreme weather.
Zinmag® substrate structure with 5-layer synergistic protection
- Zinc (Zn): Zinc is the dominant component in the plating layer, with a large-sized plating film located on the top layer. This is the first layer of protection, forming a strong shield against corrosion from the environment, protecting the product surface from harmful agents.
- Aluminum Grade (Al): Aluminum is in the form of spherical particles, small in size, located in the middle layer. This aluminum layer further provides a second layer of protection, which enhances its resistance to the ingress of corrosive elements, while resisting oxidation and extending the life of the product.
- Magnesium (Mg): Magnesium is arranged in the form of plates, alternating between aluminum and zinc, creating a tight bond between the layers. This magnesium layer plays an important role in capturing common corrosive agents, protecting products from negative environmental impacts.
- MgZn2 (Magnesium-Zinc Alloy): Magnesium and zinc combine to form the MgZn2 alloy in the form of a large oasis-shaped plate. This alloy acts as a barrier against special corrosive agents, especially chemicals, which enhances product protection in highly corrosive environments.
- Fe-Zn (Fe-Zn intermetallic): The last layer is a combination of zinc and steel substrate, forming the Fe-Zn intermetallic phase. This is an additional layer of protection for the foundation steel, which helps prevent the penetration of residual chemicals and protects the foundation steel from corrosion, ensuring long-term durability for the building.
Not only has 5-layer synergistic protection, Zinmag® Color also owns a high-end paint system, including SPE, SMP and PVDF paints. These paints not only help resist corrosion, but also bring many outstanding advantages such as anti-peeling, anti-fading, anti-dust, and especially Zinmag® also owns a completely lint-free surface to help increases uniformity on the surface, increases adhesion to the paint film and increase the aesthetics of the product.
Outstanding Benefits and Features
With a 5-layer coating structure with a protective complex and a high-quality paint system, Zinmag® Color is an ideal product for buildings that need long-term protection, which is widely applied such as: square corrugated sheet roofing sheet, round corrugated sheet, seamlock sheet , kliplock sheet, roofing sheet, gutters, roller shutters and signs in environments from C1 to C5x.

Zinmag® Color not only provides excellent protection, but also enhances the aesthetics of the building thanks to its beautiful and uniform surface. This is the perfect choice to help construction projects stay sustainable and beautiful over time.
