FAQ:
Q1: How do we guarantee the quality of our products?
A1: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.
Q2: What makes stainless steel stainless?
A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

- Q: How are steel rebars used in railway track construction?
- Steel rebars are used in railway track construction to reinforce the concrete sleepers or ties that support the tracks. They provide strength and stability to the tracks, ensuring they can withstand the heavy loads and constant vibrations of trains passing over them. The rebars are embedded within the concrete during the sleeper casting process, enhancing the overall durability and longevity of the railway tracks.
- Q: What are the common problems associated with steel rebars in concrete structures?
- Steel rebars in concrete structures can encounter numerous issues, including corrosion, inadequate cover, improper placement, and improper anchorage. Corrosion is a major concern as it weakens rebars when they are exposed to moisture and oxygen, particularly in coastal areas or regions with high humidity. This can lead to structural deterioration and reduced load-bearing capacity. Insufficient concrete cover over rebars, known as inadequate cover, is another problem. This can arise from construction practices or design errors. Inadequate cover increases the risk of corrosion as the rebars are exposed to external elements. It can also compromise the concrete's structural integrity, especially in terms of fire resistance and durability. Improper placement of rebars can also cause issues. If they are not aligned or spaced correctly according to design specifications, weak sections can form within the concrete. This can lead to uneven load distribution and potential structural failure. It can also diminish the effectiveness of rebars in reinforcing the concrete, compromising the overall strength of the structure. Improper anchorage of rebars is a common problem as well. Adequate anchorage is crucial for transferring loads between different sections of the concrete structure. If rebars are not properly anchored, they may slip or pull out under stress, reducing the structural strength and stability of the concrete. To address these problems, it is vital to implement proper construction practices and adhere to design specifications. This includes ensuring sufficient concrete cover, accurate placement and alignment of rebars, proper anchorage, and the use of corrosion-resistant rebars or protective coatings in corrosive environments. Regular inspections and maintenance are also necessary to detect and address any potential issues with steel rebars in concrete structures.
- Q: Can steel rebars be used in the construction of underground tunnels?
- Yes, steel rebars can be used in the construction of underground tunnels. Steel rebars are commonly used in tunnel construction to reinforce the concrete structures and provide strength and durability. They help to maintain the structural integrity of the tunnel, resist the forces exerted by the surrounding soil, and ensure the safety of the tunnel over its lifespan.
- Q: What are the advantages of using deformed steel rebars?
- There are several advantages to using deformed steel rebars in construction projects. Firstly, the deformed shape of the rebars provides enhanced bonding with the surrounding concrete. The ridges, bumps, or indentations on the surface of the rebar increase the surface area in contact with the concrete, resulting in improved adhesion. This ensures a stronger bond between the rebar and the concrete, making the overall structure more resistant to forces such as tension, compression, and shear. Secondly, deformed steel rebars offer better resistance to slippage. The irregular surface of the rebar prevents it from easily slipping or moving within the concrete. This is particularly beneficial in structures subject to seismic activity or heavy loads, as it helps to maintain the integrity and stability of the construction. Additionally, the use of deformed steel rebars enhances the overall structural strength and durability of the project. The deformations on the surface of the rebar allow it to better absorb and distribute stress, making it less susceptible to cracking or failure under high loads. This strength and durability make deformed rebars suitable for a wide range of applications, including bridges, high-rise buildings, and industrial structures. Furthermore, deformed steel rebars provide cost-effectiveness in long-term maintenance. The improved bond between the rebar and concrete reduces the risk of corrosion and deterioration over time. This leads to reduced maintenance and repair costs, as the structure remains more resilient and less prone to structural degradation caused by environmental factors. Lastly, deformed steel rebars offer versatility in design. The various types and sizes of deformed rebars available in the market allow engineers and designers to choose the most appropriate option for their specific project requirements. The flexibility in design ensures that the rebars can be tailored to meet the structural demands of different applications, thus contributing to the overall efficiency and safety of the construction project. In conclusion, the advantages of using deformed steel rebars include enhanced bonding with concrete, resistance to slippage, improved structural strength and durability, cost-effectiveness in maintenance, and versatility in design. These advantages make deformed steel rebars a preferred choice in construction projects where strength, stability, and long-term performance are crucial factors.
- Q: Can steel rebars be used in the construction of tunnels?
- Yes, steel rebars can be used in the construction of tunnels. Steel rebars are commonly used as reinforcement in concrete structures, including tunnels. They provide strength and stability to the concrete, making it capable of withstanding the loads and stresses experienced in tunnel construction.
- Q: What is the effect of steel rebars on the weight of a structure?
- Steel rebars have a notable impact on the weight of a structure. Typically composed of steel, these reinforcement bars possess a high strength-to-weight ratio. When integrated into a structure, they bestow strength and rigidity without significantly augmenting the overall weight. By reinforcing concrete with steel rebars, the structure becomes more capable of withstanding diverse forces and stresses, including tension, compression, bending, and shearing. This reinforcement empowers the structure to bear heavier loads and elevates its durability and longevity. While steel rebars confer strength to the structure, they do not make a considerable contribution to its weight. Consequently, this is advantageous as it facilitates the construction of lighter and more efficient structures. The reduced weight presents several benefits, such as lower construction expenses, diminished material requirements, decreased transportation costs, and improved seismic performance. Furthermore, the utilization of steel rebars also permits the construction of slimmer and visually pleasing structures. The heightened strength provided by the rebars allows for the employment of thinner concrete sections, leading to sleek designs and more open spaces. In conclusion, the effect of steel rebars on the weight of a structure is minimal. Instead, their principal role lies in enhancing the structural integrity, strength, and durability of the edifice without burdening it with excessive weight.
- Q: Are there any limitations or restrictions on using steel rebars in construction?
- Yes, there are certain limitations and restrictions on using steel rebars in construction. Here are some of them: 1. Corrosion: Steel rebars are prone to corrosion when exposed to moisture and certain chemical environments.
