G235 galvanized steel is the US standard galvanized steel, with a zinc coating on the surface. G235 means the zinc content is 2.35 ounces per square foot. The surface structure has a crystalline pattern, varying in size, high brightness, and superior corrosion resistance. They can be found in roofing, windows and doors, warehouses, fences, appliances, and other areas. Wanzhi Steel stocks G235 plates of different thicknesses, which can be cut to length and width freely. You have many steel base options. We also provide slitting, pressing, embossing, and perforation machining. If you are interested, you can ask us for more.

G235 is the American standard for galvanized sheet metal in ounces per square foot. It refers to the use of hot-dip or electro-galvanized zinc plating on the surface of a steel sheet to prevent rust and thus extend its service life. G235 means that there are 2.35 ounces of zinc plated per square foot of area((Summary of both sides)). Converted to Chinese standard units, this is equivalent to 717.2 grams of zinc per square meter of plating, or Z700 galvanized steel, which means that 700g of zinc is plated on the surface of each square meter of steel sheet.

Architectural Uses
G235 galvanized steel and Z700 galvanized steel are the same in nature; they both represent steel sheets with a high thickness of galvanized coating, the main difference between them is the naming and the different standards followed.
Item | G235 Galvanized Steel | Z700 Galvanized Steel |
Standard | Compliant with U.S. galvanized sheet metal standards | Follows the nomenclature of Japan or other regions that have adopted similar standards. |
Naming | G235 indicates a zinc coating of 2.35 ounces per square foot of surface area. | “Z” stands for cold rolled steel sheet, and ‘700’ indicates a tensile strength of 700 MPa and 700 g of zinc per square meter. |
Properties | Both have good corrosion resistance and mechanical properties, and both have a bright, shiny surface that is easy to work with and mold. | |
Uses | Both are widely used in many areas such as construction, appliances, automotive, marine, vehicles, highways, agriculture, transportation, container manufacturing, etc. |

The quality inspection of G235 galvanized steel requires comprehensive inspection of appearance (no missing zinc layer, bubbles, cracks), zinc flower morphology, surface oil, black spots, white rust, cutting edge quality (no burrs, curling), coating integrity (no exposed steel base in the cutting or punching part), zinc layer weight, tensile test, bending test, tape test, salt spray test, thickness tolerance inspection, chemical composition and other factors, and accepts third-party quality inspection at any time.
