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. 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 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 for much more costly stainless steel and aluminum post-dip batch coated steel products are ideal candidates to convert to cost saving ZAM® coated sheet.
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.
