The answer is simply that it is difficult todirectly measure the thickness accurately. 0000028017 00000 n The answer is simply that it is difficult to directly measure the thickness accurately and precisely. API SPEC 5LD CRA Clad or Lined Steel Pipe. The bending performance of zinc coated sheets with coating masses up to 275g/m2 can be regarded as equal to that of corresponding uncoated sheets. Q. In general, zinc (Z) coating endures severe deformations thanks to its ductility and good frictional behavior. same thickness (G90 [Z275] galvanize and AZ50 [AZM150] Galvalume Ò). 0000018420 00000 n Z275: 275: 20: Z350: 350: 25: Z450: 450: 32: Z600: 600: 42 * in triple spot test. 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. 0000021391 00000 n For G90, this is 0.32 oz/ft2. 0000004956 00000 n same thickness (G90 [Z275] galvanize and AZ50 [AZM150] Galvalume Ò). Only available on 0.18, 0.21, 0.23, 0.25, 0.27 and 0.30mm ISQ 550 material.
