Weather-Resistant Steel for Industrial Use ZAM Coated Steel

ZAM steel with 25-year corrosion resistance, designed for solar power plants' structural frames – features a superior

Zn-3.5%Al-3%Mg coating ideal for rooftops and ground-mounted PV systems.

Key Advantages:
* ✅ 25 Years Guaranteed Corrosion Resistance

* ✅ Superior edge and cut-surface protection

* ✅ Lightweight yet extremely strong for easy installation

* ✅ Ideal for both rooftop and ground-mounted solar farms

We proudly offer ZAM Steel, a next-generation anti-corrosion coated steel ideal for the structural systems of solar energy power plants.
Our ZAM (Zinc-Aluminum-Magnesium) coated steel features a unique composition of 93.5% Zinc, 3.5% Aluminum, and 3% Magnesium, delivering exceptional resistance to corrosion even in the harshest environments — including coastal areas and industrial zones.

ZAM steel has become a standard specification in modern solar construction tenders. Its outstanding durability at drilled, cut, and formed points makes it the most reliable solution for long-term PV infrastructure.

ZAM has been extensively tested in various environmental conditions worldwide. Results show that ZAM exhibits three times lower corrosion rates than hot-dip galvanized and pre-galvanized coatings — effectively tripling the expected service life.

Superior Corrosion Resistance
Steel is most vulnerable to corrosion where it has been mechanically affected — cut, drilled, scratched, or deformed. These points Typically become the starting zones for rust, which then spreads aggressively like cancer.
ZAM combats this by neutralizing the corrosion at its source:
* It prevents the spread of rust from the affected area
 

* Over time, it can reverse the corrosion, restoring the steel's integrity

ZAM is a high-performance mechanical coating with over 10 years of proven application history. It consists of a unique composition: 93.5% Zinc, 3.5% Aluminum, and 3% Magnesium. This exceptional blend offers maximum protection against corrosion, especially in solar energy plant mounting systems, both rooftop and ground-based.
ZAM delivers outstanding performance, particularly at the most vulnerable areas of metal surfaces — such as cut edges, drilled holes, and deformed sections — where traditional coatings typically fail. By forming a protective barrier even at these exposed
points, ZAM ensures long-lasting durability in all conditions.
This is exactly why ZAM has become a standard requirement in European solar power project specifications, and is widely used in the world’s largest solar installations as a strategic, advanced material.
