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: Can stainless steel rust?
A2: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

- Q: What is the average diameter of steel rebars used in construction?
- The average diameter of steel rebars used in construction typically ranges from 6 to 32 millimeters.
- Q: Can steel rebars be used in extreme weather conditions?
- Yes, steel rebars can be used in extreme weather conditions. Steel is a durable and weather-resistant material that can withstand varying temperatures, humidity, and even harsh weather conditions such as heavy rain, snow, and high winds. It retains its strength and structural integrity, making it suitable for use in extreme weather conditions.
- Q: Why do stirrups have thread stirrups and round bars? When are they used?
- Your question is actually related to steel and concrete work of a force of synergy in the reinforced concrete structure, steel usually is in tension, in order to ensure the reinforcement force can be well transferred to concrete, so as not to slip, we put the steel processing into whorl ribbed or other rib the shape, its purpose is to increase the adhesion between steel and concrete. Round steel is usually used in lower grade, smaller diameter reinforced steel, mainly because of its low strength, without adding ribs, round bar and concrete bonding between the relay can ensure that its strength is very good play. Therefore, steel bars are mainly used in places where the force is not large and the calculation of the reinforcement is very small.
- Q: How do steel rebars affect the overall crack width of concrete structures?
- The crack width of concrete structures is affected by steel rebars in various ways. Primarily, the reinforcement provided by rebars strengthens the concrete, increasing its resistance to cracking. This reinforcement helps distribute the tensile forces within the concrete, preventing cracks from spreading and widening. When the concrete is subjected to tensile stress, the rebars bear a significant portion of the load, reducing stress on the concrete itself and minimizing crack formation. Furthermore, the use of rebars influences the spacing and size of cracks in concrete structures. Engineers can control the crack width by incorporating rebars at specific intervals and in appropriate sizes. The rebars act as barriers that limit crack width by resisting the tensile forces exerted on the concrete. This is especially important in structures exposed to heavy loads or external forces, as it preserves the structural integrity and durability of the concrete. Moreover, steel rebars impact the propagation of cracks in concrete structures. In the event of cracks, rebars prevent their further extension. They serve as anchors, holding the cracked sections of concrete together and preventing crack spread. This is essential for ensuring overall structural stability and reducing the risk of structural failure. To summarize, steel rebars play a crucial role in influencing the overall crack width of concrete structures. They enhance concrete strength, distribute tensile forces, regulate crack spacing and size, and inhibit crack propagation. By incorporating rebars into concrete structures, engineers can effectively manage and diminish crack formation and severity, ensuring the longevity and safety of the structures.
- Q: Are steel rebars fire resistant?
- Steel rebars are generally considered to possess fire resistance. Steel, as a material, cannot burn or contribute to the spread of fire because it is incombustible. When exposed to fire, steel rebars can endure high temperatures for a prolonged duration without compromising their structural integrity. This ability is attributed to the high melting point of steel, which stands at approximately 1370 degrees Celsius (2500 degrees Fahrenheit). Moreover, during construction, steel rebars are often encased in concrete, which adds an extra layer of protection against fire. However, it is important to note that under extremely intense and long-lasting fire conditions, steel may gradually weaken and lose its ability to bear loads. Hence, fire protection measures like the application of fire-resistant coatings or fireproofing materials are sometimes implemented to further enhance the fire resistance of steel structures.
- Q: How many patterns are there in threaded steel?
- Rebar is ribbed steel, ribbed steel, including rebar. A ribbed steel bar with 2 longitudinal ribs and uniformly distributed ribs along the length. The transverse rib shape is helical, herringbone, crescent 3. Because of the function of rib, it has better bonding ability with concrete, so it can bear the effect of external force better.
- Q: What are the typical costs associated with using steel rebars in a construction project?
- The typical costs associated with using steel rebars in a construction project can vary depending on several factors. These factors include the size and type of the rebar, the quantity needed, the market conditions, and the location of the project. The cost of steel rebars is usually determined per ton or per linear foot. The price per ton can range from $400 to $600, while the price per linear foot can be anywhere between $0.75 to $1.50. It is important to note that these prices are approximate and can fluctuate based on market demand and availability. Additionally, there may be additional costs involved in the procurement and handling of steel rebars. This can include transportation fees, storage costs, and any necessary equipment or tools required for installation. Other cost considerations may include labor expenses for cutting, bending, and placing the rebars, as well as any reinforcement detailing required by the project's design specifications. These costs can vary depending on the complexity of the project and the skill level of the laborers involved. It is also essential to factor in any potential wastage or scrap material that may occur during the construction process. Proper planning and accurate measurements can help minimize these costs. Overall, the typical costs associated with using steel rebars in a construction project can be significant, but they are necessary for ensuring structural integrity and reinforcement. It is advisable to obtain quotes from multiple suppliers and contractors to ensure competitive pricing and to carefully consider the specific requirements of the project before finalizing the budget.
- Q: How do steel rebars contribute to the overall sustainability of a project?
- Steel rebars contribute to the overall sustainability of a project in several ways. Firstly, steel rebars are highly durable and have a long lifespan, which means they do not need to be replaced frequently. This reduces the consumption of resources and minimizes the need for new material production, thereby decreasing the environmental impact of the project. Additionally, steel rebars are fully recyclable. At the end of their life cycle, they can be easily collected, melted down, and repurposed into new steel products. This recycling process significantly reduces the demand for raw materials, conserves energy, and decreases the amount of waste going to landfills. Furthermore, steel rebars provide structural strength and enhance the overall safety and resilience of the project. By reinforcing concrete structures, steel rebars help increase their load-bearing capacity and resistance to external forces, such as earthquakes or extreme weather events. This ensures the longevity and stability of the project, reducing the need for repairs or reconstruction in the future. Lastly, the use of steel rebars in construction projects often results in shorter construction time and lower maintenance costs. The ease of handling and installing steel rebars allows for efficient construction processes, leading to reduced energy consumption and lower greenhouse gas emissions. Moreover, the durability and low maintenance requirements of steel rebars minimize the need for ongoing repairs and replacements, resulting in cost savings over the project's lifespan. In conclusion, steel rebars contribute to the overall sustainability of a project by being durable, recyclable, and enhancing structural strength and safety. Their use reduces resource consumption, waste generation, and energy consumption, while also providing long-term cost savings. Incorporating steel rebars in construction projects is a sustainable choice that promotes environmental conservation, economic efficiency, and social resilience.
