FAQ:
Q1: How soon can we receive the product after purchase?
A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.
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.
Q3: Can stainless steel rust?
A3: 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 are the common grades of steel rebars?
- Steel rebars are commonly classified based on their yield strength, which measures the force needed to deform or bend the steel. The most frequently seen grades of steel rebars are Grade 40, Grade 60, and Grade 75. Grade 40 steel rebars possess a minimum yield strength of 40,000 pounds per square inch (psi) and are often utilized in general construction projects that require moderate strength. Grade 60 steel rebars have a minimum yield strength of 60,000 psi and are extensively employed in reinforced concrete structures like bridges, buildings, and highways. They exhibit superior strength and durability compared to Grade 40 rebars, making them suitable for heavy-duty applications. Grade 75 steel rebars have a minimum yield strength of 75,000 psi and are commonly used in high-rise buildings, dams, and other structures that demand exceptional strength and load-bearing capacity. These rebars provide the highest level of strength and are specifically designed for structures exposed to extreme conditions or heavy loads. It should be noted that the selection of the appropriate grade of steel rebars for a specific project is determined by structural engineers, considering factors such as expected loads, environmental conditions, and design specifications.
- Q:What is the purpose of steel rebars in construction?
- The purpose of steel rebars in construction is to provide reinforcement and strength to concrete structures, preventing cracking and ensuring stability.
- Q:Can steel rebars be used in structures with high resistance to fatigue?
- Yes, steel rebars can be used in structures with high resistance to fatigue. Steel rebars are commonly used in the construction industry due to their excellent strength and durability, making them suitable for structures that need to withstand repetitive stress and fatigue. The reinforcement provided by steel rebars enhances the overall structural integrity and helps in distributing the load effectively, thus increasing the resistance to fatigue.
- Q:What are the common types of steel rebars used in bridge construction?
- In bridge construction, steel rebars are widely used, and various types are commonly employed. These types include: 1. Carbon Steel Rebars: These rebars, made of carbon steel, are the most frequently utilized in bridge construction due to their exceptional strength and durability. They are renowned for their impressive tensile strength and ability to withstand heavy loads. 2. Stainless Steel Rebars: Corrosion-resistant and possessing a high resistance to environmental factors like moisture and chemicals, stainless steel rebars are commonly used in bridge construction projects located in coastal areas or environments with high pollution levels. 3. Epoxy-Coated Rebars: By applying a layer of epoxy to carbon steel rebars, corrosion protection is provided. Epoxy-coated rebars find common usage in bridges exposed to harsh environmental conditions, such as those situated in coastal areas or subjected to de-icing salts. 4. Galvanized Rebars: Carbon steel rebars coated with a layer of zinc are known as galvanized rebars. This coating offers excellent corrosion resistance, making galvanized rebars suitable for bridge construction projects located in corrosive environments. 5. Fiberglass Rebars: Fiberglass rebars consist of glass fibers embedded in a polymer resin matrix. These rebars are lightweight, corrosion-resistant, and possess a high strength-to-weight ratio. Fiberglass rebars are often employed in bridge construction projects where reducing weight is a crucial consideration. Each type of rebar has its own advantages and is selected based on the specific requirements of the bridge construction project. Factors such as environmental conditions, load-bearing capabilities, and durability requirements play a significant role in the selection process.
- Q:What's the difference between earthquake resistant thread steel and common thread steel?
- Seismic steel can meet all the performance indexes of ordinary steel, but also can satisfy the tensile strength and yield strength of the actually measured ratio of not less than 1.25 characters; yield strength and yield strength characteristics measured standard value of the ratio is not greater than 1.30; Taiyuan dedicated steel maximum force elongation of not less than 9%, the three criteria.
- Q:Can steel rebars be recycled after the demolition of a structure?
- After a structure is demolished, steel rebars can indeed be recycled. In fact, steel is widely recycled around the globe, and rebars are no exception to this trend. Typically, during the demolition process, rebars are separated from other materials like concrete and extracted from the structure. Subsequently, these rebars are gathered and transported to a recycling facility for further processing and melting. The molten steel can then be utilized to produce new rebars or other steel goods, thus decreasing the need for fresh steel production and preserving precious resources. By recycling rebars, not only do we help reduce waste and minimize environmental impact, but we also actively contribute to the circular economy by promoting material reuse.

- Q:What is the impact of steel rebars on the overall carbon footprint of a building?
- Steel rebars have a significant impact on the overall carbon footprint of a building. The production of steel involves high carbon emissions, contributing to greenhouse gas emissions and climate change. Additionally, the extraction of raw materials and the transportation of steel rebars further increase carbon emissions. However, steel rebars provide structural strength and durability, reducing the need for future repairs or replacements. Therefore, while the use of steel rebars does contribute to the carbon footprint, proper construction practices and efficient use of materials can help mitigate their environmental impact.
- Q:Are steel rebars suitable for reinforcement in historical buildings?
- Steel rebars can be suitable for reinforcement in historical buildings, depending on various factors such as the structural requirements, the condition of the building, and the preservation goals. However, careful consideration should be given to ensure that the rebars do not compromise the historical integrity or aesthetics of the building. It is important to consult with experts in historic preservation and structural engineering to make an informed decision.
- Q:How long do steel rebars typically last before corroding?
- Steel rebars typically last for several decades before they start to corrode, depending on various factors such as the quality of the steel, environmental conditions, and the presence of protective coatings.
