Galvanized steel coil Dx51d
Building and structure field (core application):
Roof and wall system: galvanized steel coil is used as color-coated substrate or directly for roof panels and wall panels of industrial plants, warehouses, large venues, and commercial buildings, providing long-term waterproof and rust-proof protection.
Light steel structure: purlins, wall beams, supporting components, etc., with both strength and corrosion resistance.
Ventilation duct (tinplate): galvanized steel coil Dx51d is used to make air-conditioning ventilation ducts, which are corrosion-resistant, easy to process and shape, and have good sealing.
Architectural decoration: blinds, water systems, gutters, etc.
Prefabricated houses: main structural and enclosure materials.

Home appliance manufacturing industry (key materials):
Shell and back panel: The shell, side panel and back panel of home appliances such as refrigerators, washing machines, air conditioners, microwave ovens and water heaters provide good appearance substrate (need post-processing) and internal anti-rust protection.
Internal structural parts: brackets, bottom plates, inner tanks (specific models of washing machines and water heaters), etc.
Sheet metal parts: Various internal sheet metal parts of electrical appliances that require good formability and rust prevention.
Automotive industry (important applications):
Interior structural parts of the vehicle body: seat frames, beams, brackets, seat belt fasteners, fuel tank guards and other non-exposed or sub-exposed area parts, taking advantage of their high strength and corrosion resistance.
Chassis parts: some non-critical load-bearing or stone-impact-resistant parts.
Carriage and storage and transportation: truck compartment panels, tool boxes, storage and logistics equipment.
General manufacturing and metal products:
Office furniture: filing cabinets, desk frames, partition frames, etc.
Industrial cabinets and chassis: electrical control cabinets, server cabinets, instrument and meter housing substrates.
Agricultural equipment: agricultural machinery housings, granaries, feeding equipment parts.
Heating, ventilation and air conditioning (HVAC): In addition to air ducts, it also includes brackets, housings, etc.
Daily hardware: lamps, shelves, lockers, mailboxes, etc.
