S275JR/JO/J2/K2 Standard Carbon Coils JIS/EN/ASTM/GB Grade SPHC.B Q235B SS400 SM400A

Product Descrition

As hot-rolled steel coils, their specification range is similar to that of ordinary carbon steel hot-rolled coils.

1. Thickness Range:

Common thickness: 1.5 mm to 20 mm.

Thin specifications: 1.5 mm - 3.0 mm (for light structures and pipes).

Medium-thick specifications: 3.0 mm - 12.0 mm (most widely used).

Thick specifications: 12.0 mm and above (suitable for heavy-duty foundations).

2. Width Range:

Common width: 600 mm to 2200 mm.

Standard widths: 1250 mm, 1500 mm, 1800 mm, 2000 mm, etc. Widths can be customized according to downstream customers' equipment (such as leveling machines, slitting machines).

3. Coil parameters:

Inner diameter: Internationally standard is 610 mm (24 inches) or 508 mm (20 inches).

Coil weight: Typically 10 to 30 tons per coil, depending on steel mill equipment and transportation conditions.

Delivery condition: Usually delivered in hot-rolled condition with an iron oxide scale (blue or gray) on the surface.

4. Surface:

Hot-rolled black surface, ready for direct use or subsequent surface treatments such as sandblasting, pickling, and galvanizing.

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.
