Therefore, in certain applications, batch galvanizing of finished components can be substituted by using Z450 or Z600 coated sheet steel thereby simplifying the overall process chain. In general, zinc (Z) coating endures severe deformations thanks to its ductility and good frictional behavior. Z275 275 0.040 AZ150 150 0.040 AZ180 180 0.050 (1) The coating thickness allowance for Galvanneal or wiped coat is normally disregarded. a minimum G90 (Z275) or heavier is recommended, and for additional protection in corrosive or polluted environments, prepainted galvanized products should be considered. These properties make zinc coatings well suitable to forming and demanding corrosive atmospheres. Step 4: Select Size.

The corrosion resistance provided by the zinc coating is in direct proportion to the coating's thickness. The compatibility of the surface with the adhesive used should always be considered case by case. 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.). The metal coating has an advantageous characteristic of serving as lubricant, which works greatly with low and moderate surface pressures taking place in forming. A specific thickness is applied to the entire sheet, for example pre-galvanized Z275 steel has a 275g per square meter zinc coating. CRA clad pipe or lined steel pipes for oil and gas industry.

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. Z275 zinc coatings are normally produced with a minimum spangle suitable for both painted and unpainted applications. Agway uses G90 (imperial) or Z275 (metric) coating weight to insure a long life for the product. Orbis HRC CIS … For G90, the total of the per-side average coating weights must be 0.90 oz/ft2. Resistance welding methods, like spot welding, are most common and give excellent results with metal coated steels. 0000008710 00000 n 0000021391 00000 n E-mail: Pipes2018@163.com .

For all outdoor applications where the Galvanized material is bare and not painted a minimum G:90 (Z275)is recommended, and for additional protection in corrosive or polluted environments, heavier coated products should be considered. The answer is simply that it is difficult to directly measure the thickness accurately and precisely. pre-galvanized materials are used for a wide variety of products including conduit, lip and open channels. SDI 112-2008 2 Purpose It is the intent of this document to provide information regarding the zinc-coated sheet used in steel door and frame construction when a requirement for zinc-coated 0000001256 00000 n Example: G90 (0.90 oz/ft2) = Z275 (275 g/m2) Contact person: Irina Li. G90 is not a galvanizing specification; it is a coating thickness designation in the galvanizing specification ASTM A653. The successful forming of metal coated steels depends on selections made regarding the geometry of component, steel grade, metal coating type and thickness, surface quality and protection, and a tool used in the forming. Example: G90 (0.90 oz/ft2) = Z275 (275 g/m2). 0000077760 00000 n 0000020431 00000 n 260 270 280 290 300 310 320 330 340 350 360 370 380 390 400 410 420 430 440 .

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. 0000015231 00000 n Zinc coating provides a good substrate for painting when the surface is prepared correctly and right paints are used. Therefore, in order improve weldability and achieve longer service life of welding electrodes, it is recommended to avoid unnecessarily thick coatings in welding applications. 0000001884 00000 n 0000015764 00000 n same thickness (G90 [Z275] galvanize and AZ50 [AZM150] Galvalume Ò).
