G235 galvanized steel

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.

What is G235 Galvanized Steel?

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.

Characteristics of G235 Galvanized Steel

• Strong corrosion resistance: Wanzhi Steel uses continuous hot-dip galvanizing to cover the surface of the steel plate with a zinc layer, which acts as a protective layer to isolate the substrate from the outside world, preventing direct contact with air, water, and corrosive substances, thereby improving corrosion resistance and extending service life
• High strength and good toughness: After galvanizing, G235 galvanized sheet maintains the mechanical properties of the steel itself, such as strength and toughness. It can withstand certain tensile, compressive and bending forces.
• Excellent processing performance: It is easy to process by cutting, bending, welding, stamping and other methods, and can be made into various shapes and sizes according to the project.
• Exquisite appearance: The galvanized layer on the surface has a uniform and bright silver-white luster, giving a simple and clean visual effect. It is both practical and decorative.
• Low cost: Compared with alloy steel or stainless steel, the raw material cost of G235 steel is relatively low, and the galvanizing process is relatively mature, so the cost remains at a low level. Therefore, G235 (Z700) galvanized steel is very cost-effective.

Applications of G235 Galvanized Steel

• Construction industry: used to manufacture roofing materials such as metal tiles and corrugated sheets, which can resist wind and rain erosion. Used in wall panels to provide protection and decoration for the exterior walls of buildings. In addition, it is also used to build drainage systems such as culvert pipes and guardrails.
• Automotive industry: used to manufacture various parts of automobile bodies, including internal and external parts of the body, roof panels, etc. The galvanized layer can prevent the parts from rusting and increase the service life of the car.
• Home appliance industry: used to manufacture the shells and interior parts of household appliances such as refrigerators, washing machines, and air conditioners. It has corrosion resistance, decorative effects, and easy cleaning.
• Machinery manufacturing and instrumentation industry: used to manufacture the shells of electromechanical equipment, metering devices and packaging. It can protect the internal components from the influence of the external environment and has certain strength and toughness.
• Municipal, road, advertising: can be used to manufacture signal towers, agricultural trellises, road billboards and municipal baffles, supporting structures for solar panels, and components of HVAC systems.

Architectural Uses

What is the difference between G235 Galvanized Steel & Z700 GI Steel?

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.

G235 Galvanized Steel Production Process

Uncoiler → double shear → welder-notcher → inlet accumulator → pre-cleaning section → heating furnace → hot bridge → zinc pot → air knife → aftercooler → water quenching → dryer → leveling machine → dryer → drawing machine → dryer → chemical sprayer → chemical furnace → cooler → outlet accumulator → oil injector → outlet shear → tension winder.

Quality inspection

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.

Purchase-Maintenance Guide

• Confirm the use environment: For highly corrosive environments (such as coastal areas), it is recommended to choose products with a higher zinc layer weight.
• Consider subsequent processing: If painting is required, small zinc flowers or products with special surface treatment should be selected.
• Matching strength requirements: Select a substrate with appropriate strength according to the load-bearing requirements.
• Certification requirements: Check whether the product complies with local building regulations and relevant certifications (such as CE, RoHS, etc.).
• Price: Products with strict quality mean that the price will not be very low. Be careful to prevent low-price traps. It is recommended to choose a reputable supplier with guaranteed service.
  Storage: Avoid harsh environments such as moisture and corrosion, and avoid direct contact with other metals.
