Sheet Metal Fabrication: ZAM vs. Stainless Steel for Transportation Projects

zam sheet metal fabrication.jpgFrom large hoods to mufflers, transportation projects require a number of metal-based parts in order to create a finished product. When developing and creating these parts, various factors need to be considered in terms of sheet metal fabrication -- including strength, longevity, and cost.


With the invention of ZAM -- a hot-dip coating -- sheet metal fabrication is reaching new heights, especially within the transportation industry. Haven’t yet considered this revolutionary technology? Here’s how it compares to stainless steel.


Sheet Metal Fabrication: What Is ZAM?

ZAM stands for zinc, aluminum and magnesium alloy coated steel. More specifically, ZAM consists of:

  • 91% zinc
  • 6% aluminum
  • 3% magnesium

Exclusively produced by Wheeling-Nisshin, the company has deemed ZAM the "corrosion protection of the 21st century."


Overall, ZAM will:

  • Last longer than comparable products, even in the most severe conditions.
  • Reduce costs because it requires less maintenance.
  • Offer cutting-edge rust protection.
  • Replace more costly alternatives, such as stainless steel and aluminum.
  • Offer greater protection through a thinner coating, making it more eco-friendly.
  • Eliminate the need for hot-dip galvanization.

Comparing ZAM and Stainless Steel

There's no denying the effectiveness of stainless steel. It is typically cost-effective, strong, and durable. There is, however, a downside -- especially when it comes to the automotive and truck industry.


Stainless steel is certainly superior to most other metals and alloys, but under harsh conditions, it will still begin to rust. This is why ZAM was created -- to offer greater protection for a fraction of the price.

In terms of transportation projects, this option can be used for areas that often develop corrosion, including:

  • Doors
  • Hoods
  • Fenders
  • Other parts that require protection

By offering a fine, tight protective film, ZAM allows a steel base to effectively resist corrosion. Since automobiles and trucks are exposed to harsh conditions, this product will lower maintenance while expanding service life.


As stated by the CEO and president of Wheeling-Nisshin: “This product is five to 10 times stronger than existing coatings and is suitable for a wide array of end-uses.”

Offering greater stability in the long term, ZAM saves money, time, and resources.


Be Proactive About Protection

Overall, when it comes to corrosion resistance, cost and practicality, ZAM blows the competition out of the water. By incorporating ZAM into the sheet metal fabrication process, the end user can take a more proactive approach -- ensuring greater functionality and, more importantly, increased longevity.
