Grade Q235,SPHC,08F Carbon steel black steel coils used for Deep-drawn parts
Product Descrition
Steel coils are mainly divided into two categories in terms of size: hot-rolled coils and cold-rolled coils, with significant differences.
1. Hot-rolled steel coils
Thickness: 1.2mm ~ 25.4mm is the mainstream range.
Thin specifications: 1.2mm ~ 3.0mm (commonly used for welded pipes and light structures)
Medium-thick specifications: 3.0mm ~ 13.0mm (most widely used, in structures and machinery)
Thick specifications: 13.0mm and above (used in heavy machinery and special structures)
Width: 800mm ~ 2200mm is common. The most commonly used widths are 1250mm, 1500mm, and 1800mm. The width is customized according to the requirements of downstream equipment (such as leveling machines and pipe welding machines).
Coil weight/inner diameter/outer diameter:
Coil weight: Usually 10 ~ 35 tons/coil. The greater the weight, the better the continuity of production and use, but heavy equipment is required for lifting.
Inner Diameter: International standards typically use 610mm (24 inches) or 760mm (30 inches). Domestically, 508mm and 610mm are common.
Outer Diameter: Generally not exceeding 2000mm, limited by transportation and lifting requirements.
2. Cold-Rolled Steel Coils
Thickness: 0.15mm ~ 3.0mm is the mainstream range.
Extremely Thin Specifications: 0.15mm ~ 0.4mm (used for precision electronic components and packaging)
Common Specifications: 0.4mm ~ 1.2mm (automotive steel sheets, appliance steel sheets)
Thicker Specifications: 1.2mm ~ 3.0mm (used for structural components with high surface and dimensional requirements)
Width: 600mm ~ 2100mm. Common widths include 1000mm, 1219mm, 1250mm, and 1500mm. Width selection should match the final product dimensions to reduce waste.
Roll Weight/Inner Diameter/Outer Diameter:
Roll Weight: Typically 5 ~ 25 tons/roll. Due to the thinner material, the same weight of roll material can be produced in longer lengths.
Inner Diameter: Internationally standard is 610mm (24 inches), but 508mm and 610mm are commonly used domestically.
Outer Diameter: Generally ≤ 1800mm.

Applications:
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.
