Product Introduction

Carbon steel coil, a versatile rolled steel product, is manufactured by reducing the thickness of hot-rolled or cold-rolled carbon steel sheets into coils. It is widely used in construction, automotive manufacturing, home appliances, and industrial equipment due to its excellent mechanical properties, processability, and cost-effectiveness. Depending on the production process, it is divided into hot-rolled carbon steel coil (HRC) and cold-rolled carbon steel coil (CRC). HRC has higher strength and toughness, suitable for structural components and pipelines, while CRC has a smoother surface, precise dimensions, and better formability, making it ideal for precision parts, automotive panels, and electrical enclosures.

Carbon steel coils adhere to various international standards, such as China's Q235, Q345, Japan's SS400, SPHC, Germany's St37-2, St52-3, and America's ASTM A36, SAE1006-1020. These grades differ in carbon content, yield strength, and elongation, catering to diverse application needs. Special grades like deep-drawing steel (DC01-DC07, SPCE) and high-strength low-alloy steel (B510L, QStE380TM) further expand their use in high-performance fields such as automotive lightweighting and heavy machinery.

About Us

Zhongxi Metal is a professional manufacturer engaged in the research, development, production, sale and service.,  is committed to providing one-stop steel procurement services for global client. 

We can provide following three categories carbon steel:

• Low-carbon steel with a carbon content of between 0.04% and 0.30% is the largest category of carbon steel.

Properties: High toughness; Low tensile strength; High weldability; Low cost; High ductility; Low hardness; High machinability.

• Medium carbon steel with typical carbon values between 0.31% and 0.60% and manganese content between 0.31% and 0.60%

Properties:Medium strength; Moderate toughness; Medium weldability; Medium ductility; Moderate machinability.

• High-carbon steels are often referred to as “carbon tool steels” and typically contain between 0.61% and 1.50% carbon.

Properties: High toughness; Low machinability; High strength; Moderate weldability; Low ductility.

Advantage of Carbon Steel Coils

• High strength: Carbon steel coil is a type of steel containing carbon elements, which has high strength and hardness and can be used to manufacture various machine parts and building materials.

• Good plasticity: Carbon steel coil can be processed into various shapes through forging, rolling, and other processes, and can be treated with chromium plating, hot dip galvanizing, etc. on other materials to improve corrosion resistance.

• Low price: Carbon steel coil is a common industrial material, which is relatively inexpensive compared to other alloy steels due to its easy availability of raw materials and simple process.

We have our own Physical & Chemical Testing Center Lab to guarantee our product quality. Our test items & instrument fully meet international standards.

Application of Carbon Steel Coils

1. Construction field:

Carbon steel coils are used to manufacture building structural parts such as steel bars, beams, columns, bridges, etc., to increase strength and toughness and improve structural stability.

Steel structure buildings have the advantages of large span, high strength, reliable quality, and superior seismic performance, which are in line with the green transformation and carbon emission reduction goals.

2. Automotive industry:

Carbon steel coils are used to manufacture automobile bodies, chassis, engine parts, etc., meeting the requirements of high strength and flexibility.

3. Household appliances:

Carbon steel coils are used to manufacture the shells and structural parts of home appliances such as washing machines, refrigerators, and microwave ovens, taking advantage of their good plasticity and toughness.

Cold-rolled carbon steel coils provide high-precision surfaces and excellent formability, suitable for home appliance manufacturing.

4. Machinery manufacturing:

Carbon steel coils are used to manufacture mechanical parts such as bearings, gears, connecting rods, crankshafts, as well as hand tools such as hammers, screwdrivers, and pliers.

Medium carbon steel and high carbon steel are suitable for manufacturing mechanical parts with high wear resistance and high strength requirements due to their high strength and hardness.

5. Energy Industry:

Carbon steel coils are used for oil well casings and pipes in the oil and gas industry to withstand extreme temperature and pressure environments.

Thermal power generation and nuclear power plants use carbon steel to manufacture boilers, steam pipes and pressure vessels to meet the stability requirements under high temperature and high pressure.

6. Knives and kitchenware:

High carbon steel coils are used to make tools such as knives, planers, saw blades, etc. to keep the blades sharp and durable.

Carbon steel coils are also used to make kitchenware such as knives, pots and pans because of their good thermal and electrical conductivity, which is easy to maintain and clean.

7. Furniture and decoration:

Carbon steel coils are used to manufacture furniture and decorations such as tables, chairs, furnishings and lamps, providing beautiful and durable enjoyment.

8. Industrial equipment:

Carbon steel coils are used to manufacture industrial equipment such as chain conveyors, scraper conveyors, laser cutting machines, etc., to meet the requirements of heavy load, wear resistance and high temperature.
