Press-Formable Corrosion-Resistant Coated SteelMay 21, 2019
Follansbee, WV-based NS Wheeling-Nisshin has debuted Zam, a corrosion-resistant hot-dip coated steel-sheet product. Coated with a zinc-aluminum-magnesium alloy, Zam provides built-in cut-edge rust protection, and promotes cost savings through less maintenance, according to company officials who note that post-dip batch-coated products are ideal candidates for conversion to the coated sheet. In addition, the company promotes the product as an excellent substitute for more costly stainless steel and aluminum.
Zam, produced to ASTM A1046/ A1046M Type 1 specifications, reportedly provides a self-healing, ecologically friendly alternative to conventional metal coatings and exhibits exceptional alkaline resistance, even in direct contact with concrete and mortar. With a harder and smoother coating layer than hot-dip zinc-coated steel sheets, according to company officials, it shows excellent press formability and can be welded.
Suitable applications include automotive, construction, agricultural, HVAC and more. Five different chromium-free treatments are available to suit various applications, with all treatments meeting environmental regulations.
Zam can be prepainted or color-coated, with NS Wheeling-Nisshin working with major paint suppliers and construction associations to gain full acceptance of the newly introduced coating in the United States and Canada.
