5. FAQ
We have organized several common questions for our clients，may help you sincerely:
①Is this product same as W beam？
In the United States, the most commonly mentioned I-beam is the wide-flange (W) shape. These beams have flanges in which the planes are nearly parallel. Other I-beams include American Standard (designated S) shapes, in which flange surfaces are not parallel, and H-piles (designated HP), which are typically used as pile foundations. Wide-flange shapes are available in grade ASTM A992,[4] which has generally replaced the older ASTM grades A572 and A36.
②How to inspect the quality？
We have a professional inspection group which belongs to our company. We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
③Is there any advantage about this kind of product?
Steel I beam bar IPE has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often preferred.
- Q: What is the role of steel rebars in preventing cracks in concrete?
- The role of steel rebars in preventing cracks in concrete is to provide reinforcement and strength to the structure. As concrete is strong in compression but weak in tension, the addition of steel rebars helps to distribute the tensile forces and resist cracking. The rebars act as a framework within the concrete, absorbing and dispersing the tension caused by external forces, such as loads or temperature changes. This reinforcement helps to increase the overall durability and structural integrity of the concrete, reducing the likelihood of cracks forming and ensuring the longevity of the construction.
- Q: Can steel rebars be used for both residential and commercial construction?
- Steel rebars can serve for both residential and commercial construction purposes. They are widely employed as reinforcement in concrete structures to enhance their robustness and stability. Steel rebars are suitable for diverse construction endeavors such as residential buildings, commercial establishments, bridges, and infrastructure projects. By incorporating steel rebars, the concrete structure becomes capable of withstanding considerable loads, seismic activity, and other external forces. Regardless of whether it is a modest residential dwelling or a substantial commercial complex, steel rebars are a dependable and extensively utilized material for reinforcing concrete structures in both residential and commercial construction settings.
- Q: What are the different types of steel used in the production of rebars?
- There are several different types of steel that are commonly used in the production of rebars. The choice of steel depends on various factors such as the desired strength, corrosion resistance, and cost. 1. Mild Steel: This is the most common type of steel used in rebars. It has a low carbon content and is relatively inexpensive. Mild steel rebars are suitable for general construction purposes where high strength is not a requirement. 2. High Strength Deformed Bars (HSD): HSD bars are made from carbon steel with higher yield and tensile strength compared to mild steel. These rebars are commonly used in reinforced concrete structures that require higher load-bearing capacity, such as bridges and high-rise buildings. 3. Carbon Steel: Carbon steel rebars are made from steel alloyed with carbon, which enhances its strength and durability. These rebars are often used in construction projects that require resistance to extreme temperatures and high tensile strength. 4. Stainless Steel: Stainless steel rebars contain a high amount of chromium, which provides excellent corrosion resistance. These rebars are commonly used in coastal areas or structures exposed to high humidity, as they prevent rusting and maintain structural integrity over time. 5. Epoxy-Coated Steel: Epoxy-coated rebars are made by applying a protective coating of epoxy resin on the surface of the steel. This coating provides an additional layer of corrosion resistance, making these rebars suitable for structures exposed to harsh environmental conditions or chemicals. 6. Galvanized Steel: Galvanized rebars are coated with a layer of zinc, which provides excellent corrosion protection. They are commonly used in areas with high humidity, where corrosion is a significant concern. 7. Alloy Steel: Alloy steel rebars are made by adding various elements such as manganese, nickel, or chromium to enhance their mechanical properties. These rebars offer increased strength, improved ductility, and resistance to fatigue, making them suitable for specialized applications such as seismic zones or heavy construction. It is essential to select the appropriate type of steel rebar based on the specific requirements of the construction project to ensure durability, safety, and longevity of the structure.

- Q: How are steel rebars classified based on their shape?
- Steel rebars are classified based on their shape into different categories such as plain round bars, deformed bars, and ribbed bars.
- Q: How are steel rebars cut and bent on-site?
- Specialized tools and equipment are utilized on-site to cut and bend steel rebars. The process typically consists of the following steps: 1. Measurement: The rebars are measured according to the specified length and dimensions in the construction plans. This step is crucial to ensure precise and accurate cutting and bending. 2. Cutting: Various tools, such as manual rebar cutters, hydraulic shears, or portable electric cutters, are employed to cut the rebars. These tools are designed to make clean and precise cuts without damaging the rebars. The rebars are securely positioned, and the cutting tool is applied to the marked area to achieve the desired length. 3. Bending: Once the rebars are cut to the required length, they are bent using rebar benders. These machines possess different attachments and rollers to shape the rebars into the desired angle and radius. The rebars are cautiously positioned and secured in the bender, and the machine exerts force to bend them according to the specified shape. 4. Quality control: Following the cutting and bending stages, quality control checks are conducted to ensure that the rebars meet the required specifications. This may include visual inspections, measurements, and testing to verify the accuracy of dimensions and the quality of cuts and bends. It is important to note that skilled workers, such as ironworkers or steel fixers, typically assume responsibility for on-site rebar cutting and bending. They possess the expertise to interpret construction plans, utilize the appropriate tools, and guarantee the accurate cutting and bending of rebars to meet the project's requirements.
