FAQ:
Q1: How many tons of steel products could be loaded in containers?
A1: Usually the steel products are delivered by bulk vessel because of the large quantity and the freight. However, there are no bulk vessel enter some seaports so that we have to deliver the cargo by containers. The 6m steel product can be loaded in 20FT container, but the quantity is changed according to the size, usually from 18tons to 25tons.
Q2: How do we guarantee the quality of our products?
A2: 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.
Q3: How soon can we receive the product after purchase?
A3: Within three days of placing an order, we will arrange production. The normal sizes with the normal grade can be produced within one month. The specific shipping date is dependent upon international and government factors, the delivery to international main port about 45-60days.

- Q: What are the guidelines for proper curing of concrete structures with steel rebars?
- The guidelines for proper curing of concrete structures with steel rebars include ensuring that the concrete is adequately hydrated through moist curing methods such as sprinkling water or covering with wet burlap. It is crucial to maintain a consistent and controlled temperature and humidity environment during the curing process to prevent cracking and enhance the strength development of the concrete. Additionally, it is essential to avoid rapid drying and exposure to extreme temperature variations to avoid any potential damage to the steel rebars.
- Q: 25 screw steel, how many meters per meter?
- 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: How do steel rebars contribute to the fire resistance of concrete?
- Steel rebars contribute to the fire resistance of concrete by providing structural reinforcement. In the event of a fire, the rebars help to maintain the integrity and stability of the concrete structure, preventing it from collapsing or losing its load-bearing capacity. The steel rebars also act as a heat sink, absorbing and dissipating heat away from the concrete, thereby slowing down its temperature rise and reducing the risk of structural failure.
- Q: What is the ductility of steel rebars?
- The ductility of steel rebars refers to its ability to deform under tension without fracturing. Steel rebars are known for their high ductility, allowing them to withstand significant bending and stretching without breaking. This property makes them ideal for reinforcing concrete structures, where they can absorb and distribute loads effectively.
- Q: How are steel rebars protected from corrosion in marine environments?
- Steel rebars are protected from corrosion in marine environments through the application of a protective coating, such as epoxy or zinc, or by using stainless steel rebars that have inherent resistance to corrosion. Additionally, concrete cover is provided to rebars to isolate them from direct contact with seawater, further enhancing their protection against corrosion.
- Q: How do steel rebars affect the crack resistance of concrete structures?
- The crack resistance of concrete structures is greatly improved by steel rebars, which serve a vital function. When incorporated into the concrete, rebars reinforce the structure and add to its strength. The main purpose of steel rebars is to absorb tensile forces that concrete alone cannot handle. Concrete is excellent at resisting compression forces but lacks strength in tension. As a result, when a concrete structure is subjected to tension stresses, such as those caused by external loads or temperature changes, cracks can develop. By placing steel rebars within the concrete, the structure gains the ability to withstand these tension forces. When the concrete experiences tensile stresses, the rebars carry the load and distribute it throughout the structure, preventing cracks from forming and spreading. The rebars effectively bridge the gaps in the concrete, reinforcing it and increasing its overall strength. Furthermore, steel rebars also play a role in controlling the size and width of cracks that may occur. By restricting the width and propagation of cracks, the rebars prevent them from expanding and compromising the integrity of the structure. This is particularly crucial in situations where the structure is exposed to excessive forces or environmental conditions that can lead to cracking. Additionally, steel rebars contribute to the durability of concrete structures by enhancing their resistance to corrosion. Concrete is porous, and over time, water and other corrosive substances can infiltrate and degrade the material. However, when rebars are used, they are typically enclosed in a protective layer of concrete, known as the cover. This cover acts as a barrier, preventing the penetration of corrosive agents and safeguarding the rebars against corrosion. As a result, the long-term durability and crack resistance of the concrete structure are ensured. To summarize, steel rebars play a crucial role in enhancing the crack resistance of concrete structures by providing reinforcement and absorbing tensile forces. They prevent cracks from forming and spreading, control their size and width, and increase the overall strength and durability of the structure.
- Q: What are the different types of coatings available for steel rebars to prevent corrosion?
- There are several types of coatings available for steel rebars to prevent corrosion. These include epoxy coatings, zinc coatings, galvanized coatings, and polyethylene coatings. Each coating has its own unique properties and level of protection against corrosion.
- Q: How do steel rebars affect the overall aesthetics of a building?
- Steel rebars do not have a direct impact on the overall aesthetics of a building as they are typically concealed within the concrete structure. However, their presence is crucial for structural integrity and ensuring the building's safety, which indirectly contributes to the overall aesthetics by allowing for more creative and innovative architectural designs.
- Q: How are steel rebars used in the construction of oil and gas refineries?
- The strength and durability of steel rebars make them widely used in the construction of oil and gas refineries. These rebars, made from high-strength steel, reinforce concrete structures and increase their load-bearing capacity. In the construction of oil and gas refineries, steel rebars are primarily utilized in various reinforced concrete structures like foundations, columns, beams, slabs, and walls. These structures are crucial for supporting heavy equipment, storage tanks, processing units, and other essential refinery components. During construction, rebars are embedded in the concrete, forming a reinforced framework that can withstand high loads, seismic activity, and extreme weather conditions. The steel reinforcement enhances the concrete's tensile strength, making it more resistant to cracks and structural failure. Furthermore, the use of rebars ensures the long-lasting nature of refinery infrastructure. Oil and gas refineries operate in harsh environments with exposure to chemicals, high temperatures, and corrosive agents. Steel rebars possess excellent corrosion resistance, which is vital for maintaining the structural integrity of the refinery. Moreover, rebars facilitate the construction of complex shapes and configurations required in refinery structures. They can be bent, cut, and molded to fit specific design requirements, enabling the creation of intricate concrete structures essential for the refinery's functionality. Overall, steel rebars play a vital role in oil and gas refinery construction, providing necessary reinforcement to concrete structures. Their strength, durability, and corrosion resistance make them ideal for enduring the demanding conditions in these facilities, ensuring the safety and longevity of the refinery infrastructure.
- Q: What does "4EDT6" mean on thread steel?
- It is a kind of flat steel with a wide thickness and a large surface area. According to the thickness of different thickness of thin sheet (thickness <4mm), medium plate (thickness 4-25mm) and thick plate (thickness >25mm) three. The steel strip is included in the steel plate.
