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 company in the Americas to produce such a product.

This amazing product lasts longer in the most severe environments, provides built in cut edge rust protection, and promotes cost savings through less maintenance.

ZAM® uniquely presents a self healing, ecologically friendly alternative to other conventional metal coatings. Besides the key features listed at rightbelow, ZAM®:

  • exhibits exceptional alkaline resistance - even in direct contact with concrete and mortar
  • is a great substitute for much more costly stainless steel and aluminum

Your post dip batch coated products would be ideal candidates to convert to cost saving ZAM® coated sheet.

ZAM® is produced to ASTM A1046/A1046M Type 1 specifications and is used where the absolute best rust prevention and cut edge protection are needed.

ZAM® Applications

Suitable applications for ZAM® include: construction (architectural building panels, perforated panels, metal facades, roofing), automotive, agricultural applications (chicken grow out houses, swine containment, hoop buildings, grain bins, silos, etc.), green house structures, industrial HVAC, cooling towers, solar racking, school bus decking, swimming pool, sign posts, guardrail facades, coastal environments, cable trays, switch boxes, steel decking and framing, sound/wind/snow barriers and many other applications.
