Galvanized products are made by coating steel with zinc to increase its corrosion resistance. Common galvanized products include galvanized coils, galvanized sheets, galvanized strips, galvanized wires, galvanized tubes, galvanized profiles, galvanized bolts and nuts, painted galvanized steel, and so on. Galvanized materials can be classified according to process, product form, and application.
Classification by Galvanizing Process
Hot-Dip Galvanized Products
Steel (cold rolled steel/hot rolled steel coils) is dipped into molten zinc to form a zinc coating. This method can obtain a thicker zinc layer, with strong corrosion resistance, the steel surface will shape an irregular zinc crystal pattern ( regular spangle, large spangle, small spangle).
- Hot-dip galvanized sheet/strip.
- Hot-dip galvanized pipe.
- Hot-dip galvanized wire.
Electro Galvanized Products
Zinc is deposited onto the surface of steel through an electrochemical reaction. The zinc layer is thin, and the surface is smooth and beautiful, but the corrosion resistance is general.
- Electro galvanized sheet/strip.
- Electro galvanized wire.
Spray Galvanized Products
A process in which a zinc coating is applied to the surface of a substrate using a spraying technique, suitable for products with complex shapes or for on-site construction.
- Spray galvanized coated steel sheets.
Mechanical Galvanized Products
Zinc particles are placed in a machine together with metal parts, and the zinc particles are adhered to the metal surface by high-speed rotary friction.
- Galvanized bolts and nuts.
- Galvanized fasteners.
Classification of galvanized products
Galvanized Steel Sheet
Cold-rolled or hot-rolled steel is used as the base material for galvanizing, thickness of 0.15-6mm, and a uniform zinc layer. Suitable for roofing, home appliances, automotive shell, automotive sheet metal, chassis shell, structural parts, etc.
- Cold Rolled Galvanized Sheet
- Hot Rolled Galvanized Sheet
- Galvanized Steel Strip
Galvanized Steel Pipe
made of electro-galvanized steel and hot-dipped galvanized steel, suitable for general piping, such as water pipes, gas pipes, high-strength, high-pressure piping systems, and other environments.
- Galvanized seamless pipe: no welded joints.
- Galvanized welded pipes: made of welded steel strip.
Galvanized Wire
A metal wire with a zinc coating on the surface of the steel wire through the hot-dip galvanizing or electro-galvanizing process, 0.1-6mm in diameter, commonly used for electrical equipment, wire rope/fence/gardening tie-ups, bridge cables, power ground wires and more.
- Electro-galvanized wire: Thin zinc layer on the surface.
- Hot-dip galvanized wire: thicker zinc layer.
- Galvanized Strand
Galvanized Strip
Galvanized Strip is a thin steel strip that has been galvanized and is commonly used in the manufacture of a wide range of appliance housings, automotive parts, etc.
Galvanized Structural Parts and Profiles
Structural metal parts and metal profiles are treated by galvanizing.
- Angles/Channels galvanized
- Bolts/Nuts galvanized
Customized products
Embossed + hot-dip galvanized, galvanized + painted, etc. Galvanized materials with excellent decorative properties.
- Embossed Galvanized Sheet
- Painted Galvanized Sheet
- Self-repairing Galvanized Sheet
Classification by Application
Galvanized Products for Construction
Galvanized steel pipes, galvanized steel wires, galvanized angles, galvanized channels, etc.
Galvanized Products for Automotive
Galvanized body sheets, galvanized frames, and galvanized automotive parts require high corrosion resistance.
Galvanized products for home appliances
Galvanized sheet, galvanized strip.
Galvanized products for agriculture and farming
Galvanized netting, galvanized fencing, etc.
Infrastructure and pipelines
Galvanized pipes.
Classification According to the Coating Composite Process
Color Coated Galvanized Sheet (PPGI)
Hot dip galvanized + Roller baking paint, Weathering resistance increased by 3–5 times, color optional.
Galvanized Aluminum-Magnesium Sheet (ZAM)
Hot-dip Zn-Al-Mg alloy, is 10 times more resistant to red rust than GI.
Galvanized steel is commonly used in building structures, fences, frames, enclosures of refrigerators/washers/air conditioners and other home appliances, fences and greenhouses in agriculture, water supply, and drainage systems in cities, and also used in the transmission of oil and natural gas, etc. The Wanzhi Group provides high-quality galvanized products for a variety of industries, contact us for solutions!
