The choice of rebars or steel bars should be based on project requirements. Rebars are suitable for concrete reinforcement, while steel bars are used for large steel structures that require higher bearing capacity. For more information about specific models (such as 20MnSi rebars or SNCM220 round steel), please refer to relevant standards or manufacturer data.
Although both rebars and steel bars are steel materials for construction, they differ significantly in definition, use, and performance. The following are the main differences between the two:
1. Definition and diameter range
Rebar: Usually refers to ribbed steel with a diameter of 6-50mm, including plain round steel bars and deformed steel bars (such as spiral, herringbone, and crescent ribs), mainly used for skeleton reinforcement of reinforced concrete structures.
Steel bars: Ribbed round steel with a diameter greater than 50mm and not exceeding 100mm, often used for steel structure support of large-scale projects such as bridges, roads and other infrastructure.
2. Use difference
Rebar: The core function is to enhance the tensile strength of concrete, and form a high bond with concrete through ribs, which is suitable for house construction, high-rise structures, etc.
Steel bars: Due to the larger diameter and stronger bearing capacity, they are mostly used in large-scale steel structure projects that require higher mechanical properties, such as bridge main beams, heavy factory frames, etc.
3. Processing and performance
Processing: Rebars are formed by rolling or machining, while steel bars need to be processed using a special molding machine.
Mechanical properties: The tensile strength and yield strength of rebars are usually lower than those of steel bars, but they have better plasticity (stronger deformation ability). For example, round steel deforms more obviously before being pulled apart.
4. Materials and appearance
Material: Rebars are mostly ordinary low-carbon steel (such as 20MnSi), while steel bars may use higher-strength alloy steel.
Appearance: Rebars have ribs on the surface to enhance bonding, while steel bars may retain simpler ribs or smooth round shapes (such as some round steel).
Summary: The choice of rebars or steel bars should be based on project requirements. Rebars are suitable for concrete reinforcement, while steel bars are used for large steel structures that require higher bearing capacity. For more information about specific models (such as 20MnSi rebars or SNCM220 round steel), please refer to relevant standards or manufacturer data.

Steel plates are alloyed products of iron, and they meet the needs of different industrial scenarios through composition and process optimization. If corrosion-resistant or high-strength materials are required, stainless steel plates or special steel plates are more suitable; pure iron is mostly used in laboratories or special electromagnetic fields.

Is the steel structure the main structure?
The core function of the main structure is to transfer loads and ensure overall safety. If the steel structure is only used for decoration or local reinforcement (such as adding a mezzanine), it does not have the function of the main structure.

Raw material composition: Molten iron is the main raw material, supplemented by scrap steel, slag-making materials (lime, fluorite, etc.) and deoxidizers (ferrosilicon, ferromanganese, etc.).

Is carbon steel plate a cold rolled plate?
The specific production process of the cold-rolled plate includes multiple rolling and annealing treatments at room temperature to obtain steel plates with a thickness of less than 4 mm. This process not only improves the surface quality and dimensional accuracy of the steel plate, but also gives it good mechanical properties and machining properties. Therefore, there are obvious differences in production process and performance between cold-rolled plates and carbon steel plates.
