About This Product
ZAM is a brand of steel that is produced by a hot-dip process like galvanized steel. The primary difference is that the coating composition is predominantly zinc, aluminum, and magnesium.
- Features a zinc-aluminum-magnesium alloy coating for superior corrosion and cut edge protection.
- Ideal for applications like roofing and agricultural structures exposed to harsh conditions.
- Available in various thicknesses and coating weights to meet diverse project specifications.
- Combines steel’s strength with an advanced coating for unmatched durability and reliability.

Key Characteristics
- Corrosion Resistance: Zinc-aluminum-magnesium coating outperforms galvanized and aluminum-zinc coatings in harsh environments.
- Cut Edge Protection: Enhanced coating provides superior resistance to corrosion at cut edges and scratches.
- Surface Finish: Offers a smooth, uniform surface suitable for aesthetic and functional applications.
How is it Made?
- Preparation: Steel sheets are cleaned to ensure optimal adhesion of the zinc-aluminum-magnesium coating.
- Hot-Dip Coating: The steel is submerged in a molten bath of zinc, aluminum, and magnesium, forming a protective alloy layer.
- Cooling and Finishing: The coated steel is cooled, inspected, and processed into coils or sheets to meet specifications.
- Optional Treatments: Surface passivation may be applied to further enhance corrosion resistance.
Common Applications
- Construction: Building panels and roofing systems, valued for unmatched corrosion resistance in harsh climates.
- Agriculture: Barns, silos, and other agricultural structures, chosen for durability in moist and corrosive environments.
- Automotive: Chassis components and underbody panels, benefiting from superior cut edge protection and longevity.
- Industrial: Equipment and fixtures as a stainless steel alternative, leveraging ZAM’s corrosion resistance in demanding settings.
