As the industry standard, ASTM A123 Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products, provides requirements for hot-dip galvanized coatings on various steel products. Agway uses G90 (imperial) or Z275 (metric) coating weight to insure a long life for the product. 0000008710 00000 n 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. Cordeck offers four popular Form Deck products, providing a wide variety of spanning and loading capabilities. Key .

For G90, this is 0.32 oz/ft2. a minimum G90 (Z275) or heavier is recommended, and for additional protection in corrosive or polluted environments, prepainted galvanized products should be considered. One advantage of adhesive bonding is that it preserves the anticorrosion properties of the coating because the coating basically remains intact in the joint area. 0000025845 00000 n 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. For G90, this is 0.32 oz/ft2. Laser welding is also ideal for metal coated materials thanks to the narrow (only few mm) weld and low heat input. But because the coat- ing will not be exactly equal on both sides, there is also a minimum allowance for the triple spot one- side average. Evaluation of G60 vs G90 galvanizing with respect to cold formed metal framing (studs in exterior wall construction) and interior metal stud or other architectural components. 0000023982 00000 n 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? The product can be pretreated by zinc-phosphating or alternative pretreatment suitable for zinc-based coated steel in receiving plant to improve the coating adhesion. 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). Zinc, which has been used to hot-dip-galvanize steel for 250 years, provides 50 to 75 years of corrosion protection in many environments. Select a product to request a store quotation.

Zinc coating (Z) - Hot-dip galvanized steel - - SSAB high-strength steel. Zinc coating provides a good substrate for painting when the surface is prepared correctly and right paints are used. Only available on 0.18, 0.21, 0.23, 0.25, 0.27 and 0.30mm ISQ 550 material. One of the advantages which pre-galvanized steel has over hot dip galvanized steel is that it has a better appearance. ASTM A123, Standard Specification of Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products, refers to products fabricated and then hot-dip galvanized … Example: G90 (0.90 oz/ft2) = Z275 (275 g/m2) Contact person: Irina Li. coating thickness 7.14 g/m2 coating mass … Ventilation of the workplace must be arranged properly because welding of zinc-based coated steels produces welding fumes containing zinc oxide. 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 S220GD, S250GD, S280GD, S320GD, S350GD 0000001256 00000 n In general, zinc (Z) coating endures severe deformations thanks to its ductility and good frictional behavior. A wide variety of g90 z275 galvanized steel options are available to you, such as aisi, din, and astm. These properties make zinc coatings well suitable to forming and demanding corrosive atmospheres. The answer is simply that it is difficult to directly measure the thickness accurately and precisely. In general, zinc (Z) coating endures severe deformations thanks to its ductility and good frictional behavior. Simply complete the form below, click submit, you will get the price list and a Hengze representative will contact you within one business day. API SPEC 5LD CRA Clad or Lined Steel Pipe. GI Z275 (G90) ZA255 (GF45) GU AZM150 (AZ50) Magnelis ZM130 Corrosion Performance of Galvanized (GI), Galfan™ (GF), Galvalume™ (GU) and Magnelis™ (ZM)* Metallic Coated Steels it should not be used, particularly alkaline (basic) environments such as against … 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. Note: since the density of the 55% Al -Zn coating is much lower than for the galvanize coating, coatings with the same thickness (20 µm) are much lighter for 55% Al-Zn (150 g/m2))than for galvanize (275 g/m2. 0000018583 00000 n Galvanize and GalvalumeTM steel should not be combined on the same building elevation because Galvanize will likely exhibit corrosion before Galvalume. All zinc-based coatings are well suited for adhesive bonding provided that the surface is matched with the adhesive (epoxy, acrylic or polyurethane adhesive) used. 1,902 g90 z275 galvanized steel products are offered for sale by suppliers on Alibaba.com, of which steel sheets accounts for 50%, steel strips accounts for 1%, and steel channels accounts for 1%. 1,902 g90 z275 galvanized steel products are offered for sale by suppliers on Alibaba.com, of which steel sheets accounts for 50%, steel strips accounts for 1%, and steel channels accounts for 1%. Small differences in surface behavior may require some changes, for instance in lubrication, tooling geometry and holding forces. 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. Example: G90 (0.90 oz/ft 2) = Z275 (275 g/m) If what we are interested in is the coating thickness, why do ASTM standards not use thickness measurements?
