Product Descrition
Carbon Steel Coil Industry Chain and Processing Flow
Carbon steel coils occupy the midstream of the steel industry chain, and their flow and processing path clearly demonstrate their core position:
Upstream: Iron ore → Coke → Blast furnace ironmaking → Converter steelmaking → Continuous casting (steel billet)
Midstream (Carbon Steel Coil Production): Steel billet → Hot rolling mill (producing hot-rolled coils) → (Optional) Pickling → Cold rolling mill (producing cold-rolled coils)
Downstream (Processing and Consumption):
Leveling/Slitting: Unrolling the steel coil and cutting it into flat sheets or narrow strips of fixed dimensions.
Stamping/Stretching: Using molds to process the flat sheets into parts of specific shapes (such as car doors).
Bending/Forming: Bending the steel sheet into angle steel, channel steel, or rolling it into welded pipes.
Welding/Assembly: Assembling the processed parts into the final product.

1. Construction and Structural Industries (Mainly using hot-rolled medium-thick coils)
Steel Structures: Used to manufacture structural components such as H-beams, I-beams, channel steel, and angle steel for factories, warehouses, stadiums, bridges, and high-rise buildings.
Building Panels: Processed into corrugated sheets and sandwich panels for roofing and walls.
Infrastructure: Used to manufacture power transmission towers, guardrails, scaffolding, etc.
2. Automotive Manufacturing (Mainly using high-strength cold-rolled and hot-rolled coils)
Body Parts: Cold-rolled sheets are used to manufacture exterior parts such as doors, hoods, and trunk lids.
Structural Components and Chassis: High-strength hot-rolled sheets are used to manufacture load-bearing and safety components such as automotive beams, chassis frames, and wheel hubs.
3. Home Appliances and Hardware (Mainly using cold-rolled and galvanized coils)
Appliance Housings: Housings and internal structural components for refrigerators, washing machines, air conditioners, and microwave ovens.
Metal Furniture: Filing cabinets, bookshelves, bed frames, tables, and chairs.
Daily Hardware: Door and window hinges, tools, utensils, etc.
4. Container and Packaging Industry
Metal Packaging: Cold-rolled sheet metal, after tin plating (tinplate) or chrome plating, is used to manufacture food cans, beverage cans, chemical drums, aerosol cans, etc.
Containers: Container bodies are manufactured using weathering steel coils.
5. Machinery Manufacturing and Industrial Equipment
General Machinery: Manufacturing machine tool housings, gears, and shaft parts (usually using medium carbon steel).
Agricultural Machinery: Tractor and harvester bodies and components.
Mining Equipment: Conveyor belt supports, mining cars, etc.
6. Pipelines and Pipelines
Welded Pipes: Steel coils (usually hot-rolled coils) are cut, continuously rolled, and welded to form straight seam welded pipes, widely used in water, gas, and oil pipelines, as well as structural pipes (such as scaffolding pipes).
7. Surface-treated derivatives (significantly expanded applications)
Carbon steel coils undergo surface treatment, which enhances their performance and allows for more specialized applications:
Galvanized coils: Hot-dip galvanized or electro-galvanized, offering excellent corrosion resistance. Widely used in building roofs/walls (color-coated substrates), automotive parts, home appliances, and ventilation ducts.
Color-coated coils: A galvanized substrate coated with colored paint/PVDF film, aesthetically pleasing and weather-resistant, directly used in building envelopes (e.g., color-coated steel sheets for airports and stadiums).
Tin-plated/chrome-plated coils: Also known as tinplate, used for food packaging cans.
Electrical steel coils (silicon steel coils): Contains silicon, exhibiting excellent electromagnetic properties, a core material for manufacturing motor and transformer cores.
