Galvanized steel, with its corrosion resistance, high strength, toughness, and cost-effectiveness, has become an indispensable material across multiple industries. Its product forms include coils, sheets, pipes, profiles, and strips, catering to the needs of various applications. Wanzhi Group provides galvanized materials compliant with standards such as EN10346, ASTM A653, and JIS G3302 for core applications in global construction, industry, infrastructure, and public welfare sectors.
Construction and Structural Engineering
Wanzhi Group offers a variety of steel solutions for the construction industry. Galvanized steel, with its excellent structural support, resistance to wind and snow loads, corrosion resistance, high strength, and weather resistance, is widely used in applications requiring long-term exposure to outdoor environments (rain, snow, UV rays, etc.).
Roofing Systems
- Roof panels: Color-coated base sheets (galvanized steel sheets + coating), profiled steel sheets (e.g., corrugated sheets, ribbed sheets), and standing seam roofing systems.
- Support Structures: Galvanized H-shaped steel, galvanized I-beam steel, C/Z-shaped galvanized purlins, galvanized steel roof trusses, and trusses.
Wall Enclosures
- Exterior Wall Panels: Galvanized profiled panels (e.g., wall panels, exterior facades, sandwich panel substrates), louvers, and ventilation grilles.
- Light steel studs: Galvanized studs for partition walls/ceilings (thickness 0.4–2.0 mm).
Accessory structures
- Stairs/platforms: Galvanized steel pipe railings, galvanized steel gratings, galvanized anti-slip tread plates, handrails.
- Door and window frames: Security doors, roller shutter door frames, and window frames made from galvanized steel profiles/galvanized steel sheets.
Piping systems
- Ventilation/plumbing/fire protection pipes: Galvanized round pipes/square pipes, etc.
Infrastructure and Public Works
- Steel structures exposed to prolonged exposure to wind, sunlight, rain, and salt fog (in coastal areas) can utilize galvanized steel or aluminum-zinc-coated steel as a substrate to resist atmospheric and salt fog corrosion.
Traffic Facilities
- Highways: Corrugated beam guardrails (Guardrail), traffic barriers, traffic signboards, galvanized highway guardrails, galvanized traffic barriers, galvanized traffic signposts and brackets.
- Railways: Galvanized angle steel/channel steel, galvanized sound barrier base plates (sandwich panels), cable trays, contact network support poles.
- Bridges: Galvanized bridge guardrails, galvanized maintenance platforms.
Energy Facilities
- Power: Transmission towers, transformer enclosures, meter boxes, galvanized cable conduits.
- Renewable Energy: Solar panel mounts (ground/roof), photovoltaic frames, internal components of wind turbine towers.
Municipal Engineering
- Water Supply and Drainage: Galvanized steel pipes (for water supply/fire protection pipelines).
- Street Facilities: Galvanized streetlight poles, bus shelters, trash bins, bench supports.
Industrial Manufacturing and Equipment
Automotive components and mechanical equipment are exposed to moisture, sand, and salt spray over extended periods. Galvanized steel offers excellent formability, high strength, and resistance to outdoor environmental corrosion, moisture, rust, industrial environmental corrosion, and corrosion from humidity and dust, making it an economically viable steel material for automotive, appliance, and mechanical production.
Automotive Industry
- Body Structure: Electrogalvanized steel sheets (EG) are used to manufacture doors and hoods, while galvanized steel tubes/structural steel are used for chassis components.
- Functional Components: Galvanized cold-rolled steel sheets are used to manufacture fuel tanks and exhaust pipe mufflers (hot-dip galvanized for high-temperature resistance).
Home Appliances and Electronics
- Housings: Galvanized steel sheets/color-coated galvanized sheets for refrigerator/washer side panels, air conditioner housings, and computer cases (electrogalvanized sheets + coating).
- Internal structures: Galvanized motor brackets, circuit board mounting components, and heat sinks.
Mechanical and Containers
- Equipment housings: Distribution cabinets, control boxes, and instrumentation boxes (galvanized steel plate bent and welded).
- Warehousing and logistics: Shelves (crossbeams/columns), hoppers, galvanized steel wire mesh storage cages.
- Industrial toolboxes: Galvanized pipes/sheets.
Agriculture and Livelihood Sector
Galvanized steel is resistant to animal chewing and moisture corrosion, moisture-proof and rust-proof, with a long service life and resistance to rainwater and UV corrosion. It is used to manufacture agricultural facilities and machinery that can withstand harsh environments such as high humidity, sand, and fertilizer corrosion.
Agricultural Facilities
- Planting/Breeding: Greenhouse frames (galvanized steel pipes/structural steel), galvanized breeding fences, galvanized feed troughs/watering systems.
- Grain Storage Equipment: Galvanized steel plate grain silos, drying towers, conveyor covers.
- Agricultural Machinery: Galvanized steel pipes/ steel plate tractor chassis, agricultural vehicle bodies, seeder/harvester components, etc. Example
Home and Commercial
- Furniture: Galvanized steel plate file cabinets, supermarket shelves, metal table and chair frames (galvanized pipes/structural steel).
- Construction materials: Ceiling joists, ventilation ducts (galvanized spiral ducts), baseboards.
Daily necessities
- Hardware: Galvanized bolts/nuts, hinges, door hinges, scaffolding connectors.
- Containers: Galvanized pipes/sheets welded/bent into water tanks, mailboxes, metal trash cans, document storage boxes.
Specialized Applications
- 5G base station brackets/antenna mounting hardware: high-zinc-coated hot-dip galvanized steel.
- Dock fenders/ship gangways: thick-zinc-coated (≥200 g/m²) hot-dip galvanized steel plates.
- Mine support frames/conveyor belt structural components: hot-dip galvanized steel strips, galvanized profiles.
