Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
- Q: Can steel rebars be used for both residential and commercial construction?
- Yes, steel rebars can be used for both residential and commercial construction. Steel rebars are commonly used as reinforcement in concrete structures to provide additional strength and stability. They are suitable for various construction projects, including residential buildings, commercial buildings, bridges, and infrastructure projects. The use of steel rebars ensures that the concrete structure can withstand heavy loads, seismic activity, and other external forces. Whether it is a small residential house or a large commercial complex, steel rebars are a reliable and commonly used material for reinforcing concrete structures in both residential and commercial construction.
- Q: Are steel rebars suitable for use in earthquake-resistant structures?
- Yes, steel rebars are suitable for use in earthquake-resistant structures. Steel rebars, also known as reinforcing bars, are commonly used in construction to provide structural strength and reinforcement. They have been proven to be effective in improving the strength and ductility of concrete structures, making them more resistant to seismic forces. During an earthquake, structures are subjected to intense shaking and ground motion. Steel rebars help in distributing and dissipating the energy generated by these seismic forces, thereby reducing the vulnerability of a structure to damage or collapse. The use of steel rebars enhances the overall structural integrity and stability, enabling buildings and other infrastructure to withstand the lateral and vertical forces associated with earthquakes. Moreover, steel rebars possess excellent tensile strength, which is crucial for seismic resistance. Unlike concrete, which is strong in compression but weak in tension, steel rebars provide the necessary reinforcement to counteract tensile stresses caused by seismic activity. This ability to resist both compression and tension makes steel rebars an ideal choice for earthquake-resistant structures. Additionally, steel rebars can be designed and installed in such a way that they provide additional ductility to a structure. Ductility refers to a material's ability to undergo deformation without fracturing. During an earthquake, structures with higher ductility can undergo significant deformations and absorb energy, reducing the risk of catastrophic failure. Steel rebars are known for their high ductility, allowing them to effectively absorb and dissipate seismic energy. In conclusion, steel rebars are highly suitable for use in earthquake-resistant structures. Their strength, ability to resist both compression and tension, and high ductility make them an essential component in ensuring the structural integrity and safety of buildings and infrastructure in seismic-prone areas.
- Q: What's the difference between primary and two grade steel and three grade steel?
- The two is the performance of classification (class), for example, China's current implementation of standards, (G B1499.2-2007) for steel wire for 1499.1-2008), according to the strength (tensile strength yield point / steel) will be divided into 3 levels; the Japanese industrial standard (JI SG3112), according to the comprehensive performance of the steel branch for the 5 species; the British Standard (BS4461), also provides some level of performance test of thread steel. In addition, the thread steel can be classified according to the use, such as reinforced concrete, ordinary steel bars and reinforced concrete bars for heat treatment.
- Q: Are steel rebars suitable for use in foundation structures?

Steel rebars, also known as reinforcing bars, are commonly used in concrete construction to provide strength and reinforcement to the structure. The use of steel rebars in foundation structures helps to increase the load-bearing capacity and durability of the foundation. Steel rebars are made from steel, which has high tensile strength and is resistant to corrosion, making it an ideal material for use in foundation structures. The rebars are placed in the concrete during construction, providing additional strength and preventing cracks or fractures in the foundation. They help to distribute the load evenly throughout the foundation, reducing the risk of settlement or failure. Furthermore, steel rebars can be easily customized to meet the specific requirements of the foundation structure. They come in various sizes, shapes, and grades, allowing for flexibility in design and construction. This versatility makes steel rebars suitable for use in different types of foundation structures, including residential, commercial, and industrial buildings. Overall, steel rebars are a reliable and cost-effective choice for reinforcing foundation structures. They enhance the structural integrity and longevity of the foundation, ensuring a solid and stable base for the entire building.
- Q: What is the process of bending steel rebars into shapes other than straight bars?
- The process of bending steel rebars into shapes other than straight bars typically involves using specialized machinery, such as a rebar bending machine or a hydraulic bender. The rebars are placed in the machine, which applies force to bend them into the desired shape. The operator may follow blueprints or use templates to ensure accurate bending. This process is commonly used in construction and concrete reinforcement projects to create custom shapes that fit specific architectural or structural requirements.
- Q: How do steel rebars affect the overall durability of concrete?
- Steel rebars have a significant impact on the overall durability of concrete structures. The presence of steel rebars in concrete enhances its strength and resistance to various external forces and environmental conditions. One of the primary functions of steel rebars is to provide tensile strength to concrete, which is otherwise weak in resisting tension. Concrete is excellent in compression but tends to crack under tension. By embedding steel rebars within the concrete, these cracks are effectively controlled and prevented from expanding, thus improving the durability of the structure. Steel rebars also help in increasing the flexural strength of concrete, making it more capable of withstanding bending and deformations. This is particularly crucial in structures such as beams, columns, and slabs that experience significant loads and forces during their lifespan. Moreover, steel rebars act as a reinforcement in concrete, improving its resistance to external factors such as earthquakes, wind, and impact loads. The presence of rebars helps in distributing and dissipating these forces throughout the structure, reducing the chances of structural failure and increasing the overall durability. Another critical aspect is the prevention of corrosion in reinforced concrete structures. The steel rebars are typically coated with materials that protect them from corrosion caused by moisture and chemical reactions. This protective coating, coupled with the alkaline environment of concrete, creates a barrier that significantly slows down the corrosion process, thereby increasing the longevity and durability of the concrete structure. In conclusion, steel rebars play a vital role in enhancing the overall durability of concrete structures. They provide the necessary tensile strength, improve flexural strength, enhance resistance to external forces, and prevent corrosion. By incorporating steel rebars, concrete becomes more robust, long-lasting, and capable of withstanding various challenges, ensuring the longevity and safety of the structure.
- Q: Can steel rebars be used in structures with limited construction permits?
- Steel rebars can typically be used in structures with limited construction permits, as they are commonly used in construction due to their strength and durability. However, it is important to consult the specific regulations and limitations outlined in the construction permits. These permits may have restrictions on the types of materials that can be used, including the size and composition of rebars. It is advisable to consult with a structural engineer or the local building authority to ensure compliance with the construction permits and to determine if steel rebars are allowed in the particular structure.
- Q: Are steel rebars suitable for use in high-traffic areas like bridges?
- Yes, steel rebars are suitable for use in high-traffic areas like bridges. Steel rebars provide exceptional strength and durability, making them ideal for withstanding heavy loads and frequent use. Additionally, steel rebars offer excellent resistance to corrosion, ensuring the longevity and structural integrity of bridges in high-traffic areas.
