Introduction to 
WHEELING-NIPPON STEEL is proud to announce our newest product, ZAM® - branded the "Corrosion Protection of the 21st Century". ZAM® is a remarkably superior corrosion-resistant hot-dip Zinc-Aluminum-Magnesium alloy-coated steel sheet product, with the best corrosion protection for steel currently available on the market. WHEELING-NIPPON STEEL is the first and only company in the Americas to produce such a product, providing unparalleled corrosion resistance, including cut-edge corrosion resistance, making it a great choice of material in applications where corrosion must absolutely be avoided.
This amazing product is protected by a proprietary alloy, a magnesium-zinc-aluminum coating that lasts longer in the most severe environments, provides built-in cut-edge rust protection, and promotes cost savings through less maintenance, making it a fantastic choice for weatherproof roofing, especially coastal roofing.
ZAM® uniquely presents a self-healing, ecologically friendly alternative to other conventional metal coatings. Besides the key features listed at right, ZAM® exhibits exceptional alkaline resistance - even in direct contact with concrete and mortar.
ZAM® is a great substitute avoiding the need to use more costly stainless steel, aluminum and post-dip batch coated steel products. Parts requiring these materials are ideal candidates to convert to cost-saving ZAM® coated sheets.
ZAM® is produced to ASTM A1046/A1046M Type 1 specifications and is utilized where the absolute best rust prevention and cut edge protection are needed.

Frequently Asked Questions on ZAM® Coated Steel Sheets
What is ZAM® coated steel, and how is it different from traditional galvanized steel?
ZAM® coated steel is a highly durable steel product coated with a blend of zinc, aluminum, and magnesium. This unique coating enhances corrosion resistance, surpassing traditional galvanized steel's performance by offering extended life and better protection in harsh environments.
What applications are best suited for ZAM® coated steel?
ZAM® coated steel is ideal for various applications, including construction, automotive, agriculture, HVAC systems, and solar panel frames. Its superior durability and corrosion resistance make it perfect for environments exposed to moisture, chemicals, or extreme weather.
How does the corrosion resistance of ZAM® coated steel compare to other coatings like Galvanized Steel or Galvalume®?
ZAM® coated steel provides significantly better corrosion resistance than conventional galvanized and Galvalume® coatings, especially in terms of durability and adhesion in cut-edge or perforated-edge applications. The magnesium content in the coating enhances self-healing properties, offering long-lasting protection even in more demanding environments.
Is ZAM® coated steel environmentally friendly?
Yes, ZAM® coated steel is designed with sustainability in mind. Its extended lifespan reduces the need for frequent replacement, and the coating process minimizes waste while maintaining high recyclability. Learn more about ZAM®'s environmental impact.
Can ZAM® coated steel be fabricated and welded like traditional steel products?
