Processing of zinc coated steel Forming. 0000010664 00000 n Because zinc is more reactive than iron or steel, the zinc galvanized coating corrodes first, protecting the steel or … Because of the sacrificial nature of the zinc, the coating provides corrosion protection for areas of exposed steel surfaces, such as cutting edges and areas where coating has damaged (scratches, impacts, etc.). 0000077801 00000 n 0.021 (26Ga) GA G90 SHEET; 0.028 (24Ga) GA G90 … In addition to these Zinc coating thicknesses defined according to EN10346:2015, the offering contains different asymmetric coatings, coatings with equal coating minimum mass per surface, and other OEM specifications that are available upon request. Consequently usually the same forming processes as for uncoated steels can be applied for zinc-based coated steels without any substantial modifications to the process conditions. About sales01. Resistance welding methods, like spot welding, are most common and give excellent results with metal coated steels. G90 Coating contributes about 1.6 mils (0.0016 inches) of thickness to the final coated sheet (or 0.0008 inches of zinc to each side of the material). h���1 0ð40�}\�`&`�'MF[����. Similarly the increase in coating thickness increases slightly the required welding current. Form Deck is perfect for floors, stairways, and more. The continuous hot-dip galvanizing process offers a wide protection range from Z100 to Z600 in addition to a tight bond between the coating and the steel. 0000070690 00000 n G90 is not a galvanizing specification; it is a coating thickness designation in the galvanizing specification ASTM A653.

To convert from oz/ft2to g/m2, multiply by 305.15 Example: G90 (0.90 oz/ft2) = Z275 (275 g/m2) If what we are interested in is the coating thickness, why do ASTM standards not use thickness measurements? Orbis HRC CIS … G90 is not a galvanizing specification; it is a coating thickness designation in the galvanizing specification ASTM A653. The compatibility of the surface with the adhesive used should always be considered case by case. 2(10 ) Total both sides Min SST* g/m2 per side Unexposed side Min SST g/m2 per side Exposed side if applicable E = Exposed U = Unexposed G = Pure Zinc A = Zinc-Iron Alloy English Designation G = Pure Zinc A = Zinc-Iron Alloy Metric Designation *TST/SST = Triple Spot Test/Single Spot Test as defined by ASTM A924. For G90, the total of the per-side average coating weights must be 0.90 oz/ft2. Agway uses G90 (imperial) or Z275 (metric) coating weight to insure a long life for the product. The answer is simply that it is difficult to directly measure the thickness accurately. What are the differences between ASTM A123 and CSA G164-18? In general, zinc (Z) coating endures severe deformations thanks to its ductility and good frictional behavior.
