G90 SGCH Galvanized Steel Prepainted Steel Coil

G90 isn't a galvanizing specification; it's a coating thickness designation within the galvanizing specification ASTM A653. Zinc coating weights are measured in ounces per sq ft and range from G90 to G60, G40, and G30 galvanized steel. G90 galvanized steel features a longer service life than G60, G40, and G30 galvanized steel, because G90 galvanized steel features a heavier coating weight of zinc applied thereto at 0.90 oz/ft^2 as against G60 galvanized steel at .060 ox/ft^2 then on. For all outdoor applications where the Galvanized material is bare and not painted a minimum G:90 (Z275)is recommended, and for extra protection in corrosive or polluted environments, heavier coated products should be considered.

g90 galvanized steel Properties
( ASTM A527 / A653 ) Galvanized Steel Sheets are intended for usewhere greater corrosion protection is required without painting. Galvanized steel is steel coated with zinc on two sides. the method wont to do that is understood because the continuous hot dip process. This process leads to a layer of zinc which adheres tightly to the bottom steel and features a spangled, or snowflake-type, appearance. The layer of zinc acts as a sacrificial coating. Galvanized Steel Sheets are easy to weld, form, and drill . With a typical protection lifetime of 20 years, Galvanized Steel Sheets are ideal for a good range of outside applications, or for decorative interior design.Magnetic, Brinell = 95, Tensile = 52,000, Yield = 38,000 (+/-)

g90 galvanized steel Applications

Galvanized sheet are often used bare, prepainted or postpainted. it's easy to fabricate and stamp and is employed for applications that need corrosion resistance. These include:HVAC equipment, Automotive parts, Electrical boxes, Enclosures and housings, Prefab and metal buildings, Roofing, Outdoor signs, Playground equipment, Equipment and machinery.

A653 Galvanized Sheet Characteristics and Applications

Galvanized steel is steel coated with zinc on two sides. the method wont to do that is understood because the continuous hot dip process. This process leads to a layer of zinc which adheres tightly to the bottom steel and features a spangled or snowflake-type appearance. The layer of zinc acts as a sacrificial coating. A653 galvanized sheet and coil are often used bare, prepainted or postpainted. It are often utilized in most fabrication processes, very similar to uncoated flat rolled sheet. Typically, galvanized sheet and coil are utilized in applications where corrosion resistance is important: air con equipment, automotive parts, display cases, electrical boxes, farm buildings, equipment and machinery, garbage cans, heating equipment, mailboxes, outdoor signs, playground equipment, prefab buildings, roofing, and vending machines are just a couple of examples.
