A Comprehensive Guide to the Applications of Galvanized Coil – A Corrosion-Resistant Metal Material for Multiple Industries

I. Construction & Infrastructure Industry

1. Enclosure Structures & Decorative Materials

• Roof/Wall Systems: Used in manufacturing color steel tiles and sandwich panels (rock wool/polyurethane core), widely applied in roofs and exterior walls of factories, warehouses, logistics centers, and prefabricated houses. The zinc layer resists wind, rain, and UV erosion, extending the building's service life (standard zinc layer thickness: 80-275g/㎡, customizable per customer requirements).

• Doors, Windows & Curtain Walls: Serves as the base material for door/window frames and curtain wall keels. After cutting, bending, and stamping, it is processed into various architectural hardware. The galvanized layer prevents rust caused by humid indoor/outdoor environments, suitable for residential buildings, commercial complexes, office buildings, etc.

• Decoration & Renovation: Used for ceilings, partitions, stair handrails, guardrails, etc. Secondary processing such as spraying and film lamination can enhance aesthetics, balancing functionality and decorativeness.

2. Infrastructure Projects

• Municipal Facilities: Road guardrails, traffic sign poles, street lamp poles, sewer manhole covers, trash bins, etc. Exposed to outdoor or humid environments for long periods, the corrosion resistance of galvanized coil reduces maintenance costs, making it ideal for urban renewal and road expansion projects.

• Water Conservancy & Communications: Water transmission pipelines and pump station equipment casings in water conservancy projects; signal tower brackets and equipment room enclosures for communication base stations. These require resistance to acid-alkali corrosion or extreme weather, making galvanized coil a preferred choice.

• Steel Structure Engineering: Beams, columns, and supports of steel-structured factories; auxiliary structures of bridges and brackets. Galvanizing prevents rust after welding and installation, enhancing structural safety.

II. Home Appliance & Electronics Industry

1. White Goods

• Refrigerators: Casings, liners, and condenser pipes (electrogalvanized coil with thin, uniform zinc layer for easy stamping and subsequent spraying).

• Washing Machines: Inner drums, casings, and base brackets (requires galvanized coil with good corrosion and wear resistance to withstand detergent erosion).

• Air Conditioners: Outdoor unit casings, heat exchanger fin substrates, and indoor unit panels (hot-dip or electrogalvanized coil balancing corrosion resistance and heat dissipation).

• Water Heaters, Microwaves, Ovens: Casings, liners, and heating tube brackets (must meet stability requirements in high-temperature environments).

2. Small Appliances & Electronic Devices

• Small Appliances (Rice Cookers, Induction Cookers, Electric Fans): Casings, bases, and control panel backplanes.

• Electronic Devices: Computer cases, server racks, printer casings, and TV backplanes (requires galvanized coil with flat, defect-free surface for subsequent processing and electromagnetic shielding).

III. Automotive Industry

1. Automobile Bodies & Components

• Body Structural Parts: Inner panels, crossbeams, and longitudinal beams of doors, hoods, and trunks (electrogalvanized coil or hot-dip galvanized alloy coil, such as zinc-iron alloy and zinc-aluminum-magnesium alloy, offering high strength, corrosion resistance, and meeting automotive lightweight requirements).

• Chassis Components: Chassis brackets, suspension system parts, and fuel tank brackets (hot-dip galvanized coil resists corrosion from road sand, rainwater, and salt, extending component lifespan).

• Interior & Exterior Parts: Seat slides, door handles, bumper brackets, and wheel cover substrates (balances formability and decorativeness).

2. Automotive Supporting Facilities

• Auto Parts Packaging: Turnover boxes and pallets for transportation (made of galvanized coil, reusable and resistant to collision and moisture during transit).

• Charging pile casings, parking lot guardrails, and automotive maintenance equipment brackets.

IV. Machinery Manufacturing & Hardware Industry

1. General Machinery

• Machinery Casings, Protective Covers, Brackets, and Workbenches (e.g., body casings and feeding guide substrates of wire drawing machines and nail making machines). Resists workshop oil and dust erosion, reducing equipment maintenance frequency.

• Agricultural Machinery: Casings, chassis components, and farm tool brackets of tractors and harvesters (e.g., auxiliary structures of plows and harrows). Operates in fields for long periods, requiring resistance to soil moisture and pesticide corrosion.

2. Hardware Products

• Metal Stamping Parts: Base material for nails, screws, nuts, and washers (cold-galvanized coil for easy cold forming, with optional zinc layer thickening via electroplating).

• Daily Hardware: Clothes hangers, drying racks, towel racks, and cabinet hardware accessories (requires galvanized coil with smooth, burr-free surface for household corrosion resistance).

• Tool Manufacturing: Handle casings and toolboxes for wrenches, pliers, and screwdrivers (balances corrosion resistance and grip comfort).

V. Packaging & Logistics Industry

• Packaging Materials: Galvanized steel buckets (chemical raw material buckets, lubricating oil buckets, food packaging buckets) with good sealing and corrosion resistance to protect internal products from contamination; base material for metal packaging foil and gift tins.

• Logistics Facilities: Warehousing shelves, pallets, turnover boxes, and courier cabinet casings (requires galvanized coil with sufficient strength and wear resistance for high-frequency use); auxiliary structural parts of containers (e.g., internal supports and floor substrates).

VI. Other Industries

• Agriculture: Greenhouse frames, insect screen frames, and irrigation pipe brackets (resists soil moisture and pesticide corrosion); agricultural machinery parts and enclosure structures of grain storage silos.

• Chemical Industry: Casings of chemical equipment, pipe brackets, and auxiliary structures of reaction kettles (requires resistance to acid-alkali gases and liquids; high-zinc or special alloy galvanized coil is optional).

• Furniture Industry: Frames and panel substrates of metal furniture (e.g., iron beds, office desks, and shelves). Formed via spraying and welding, balancing aesthetics and practicality.
