ZAM coated tubing (Zinc Aluminim Magnesium)  "ZAM® is a highly corrosion-resistant hot dip coated steel that has a coating layer of zinc, 6% aluminum, and 3% magnesium.", states the raw material producer. We use this flat rolled steel in the production of our tubing. Dimensions are produced as large as 2.50” Rd, 2.0"x2.0" Sq and 1.5"x 2.0" Rec. 

ZAM was tested up to 4,000 hours in controlled salt spray testing yielding superior results when compared to other zinc and zinc aluminum coatings. The appearance of ZAM, with a .40oz/ft² coating weight on one side and no chem treat, showed minimal white rust after 4,000 hours. Salt spray testing was performed in accordance with SST: JIS Z2371. which is very similar to the ASTM B117 standard.
