The properties of . G90 Coating: Each coated-steel sheet product has a coating weight designation system that is in common use today. Available in 50G/50G, 60G/60G, 70G/70G, 90G/90G, G30, G40, G60 and G90 coatings The Deep Drawing Steel (DDS) designation will encompass the properties of the previous Drawing Quality Special Killed (DQSK) in the specification A-642 and can be produced as stabilized steel (EDDS) at the producers option. These numbers refer to the weight (mass in SI units) of zinc on the surface of the steel sheet in Inch-Pound (English or Imperial) units of measurement. As a structural steel material with high strength, A653 steel offers excellent machinability, weldability, and forming. designation system is given in terms such as G60, G90, etc. cold-formed steel are impressive, TABLE OF CONTENTS. The system for each type of coating is defined in the appropriate ASTM standard. Commercial Steel, Deep Drawing Steel, and Extra Deep Drawing Steel are designations described in the ASTM specifications for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot Dip Process A653/A653M. The Extra Deep Drawing Steel (EDDS) designation is free from aging over time with no changes in the mechanical properties. Material certification 104 Manufacturing and sales locations 104. Chicago Metallic® G90 Exterior Grade Systems are available in a heavy-duty design, for both standard 15/16” exposed grid and 1-3/8" drywall suspension systems, and is built with HDG 90 steel. Thus the tensile strength, proof strength and tensile elongation of cold rolled steel were unaffected, except that the tensile elongation of 40% cold rolled steel tended to be increased by galvanizing. ClarkDietrich has adopted standard nomenclature ... G90 coatings are an enhanced option that Ideal for exterior applications, this drop ceiling grid features seismically approved stab-end cross tees for quick and easy assembly. That is, for G90, the coating on one square foot of sheet (total coating, both sides of the sheet) weighs a minimum of 0.90 ounces. How to identify our products.
