FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q4: What makes stainless steel stainless?

A4: 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:
Yes, there are internationally recognized standards and specifications for steel rebars. The most commonly used standards are those set by the American Society for Testing and Materials (ASTM), British Standards Institution (BSI), and International Organization for Standardization (ISO). These standards outline the requirements for steel rebars in terms of dimensions, mechanical properties, chemical composition, and testing methods, ensuring their quality and suitability for construction purposes.
Q:How many roots per ton of 18 thread steel?
18 of the rebar is one meter with a weight of 2kg
Q:
Yes, steel rebars are suitable for reinforcement in tunnels. Steel rebars are widely used in tunnel construction due to their high tensile strength, durability, and ability to resist deformation and cracking under stress. They provide structural integrity to the tunnel walls, ensuring stability and safety. Additionally, steel rebars can be easily bent and shaped to fit the desired design of the tunnel, making them a versatile option for reinforcement.
Q:
Steel rebars play a crucial role in industrial flooring construction as they provide reinforcement and strength to the concrete. By being embedded within the concrete slab, rebars help to distribute loads evenly, resist tension forces, and prevent cracking or structural failure. They enhance the durability and longevity of the flooring, making it capable of withstanding heavy loads, impact, and vibrations commonly encountered in industrial settings.
Q:
The strength and durability of concrete are greatly improved by steel rebars in several ways. Firstly, the inclusion of rebars reinforces the concrete structure, significantly increasing its tensile strength. While concrete is adept at resisting compression forces, it is weaker in tension. By embedding steel rebars within the concrete, the structure's ability to resist bending, cracking, and collapsing under heavy loads or external forces is greatly enhanced. Secondly, the presence of steel rebars prevents the occurrence of cracking and shrinkage in the concrete. As concrete dries and cures, it tends to shrink, leading to the formation of cracks. However, rebars help control and restrict this shrinkage by providing additional support and structural integrity. This effectively reduces the occurrence of cracks and ensures the long-term strength and durability of the concrete. Furthermore, the overall structural stability of the concrete is improved by steel rebars. When subjected to dynamic loads or seismic activity, concrete can undergo significant deformation or even fail. The inclusion of rebars helps distribute the load more evenly throughout the concrete structure, minimizing the risk of localized damage or collapse. This ultimately enhances the stability and safety of the concrete construction. Lastly, steel rebars contribute to the longevity and durability of concrete structures. The steel used in rebars is highly resistant to corrosion, which is a common issue in concrete exposed to harsh environmental conditions or moisture. By providing a protective layer called passivation, rebars prevent corrosion and maintain the structural integrity of the concrete over an extended period. This ensures that the concrete remains strong, durable, and resistant to degradation throughout its lifespan. In conclusion, steel rebars play a critical role in enhancing the strength and durability of concrete. They improve tensile strength, prevent cracking and shrinkage, enhance structural stability, and increase the lifespan of concrete structures. With the inclusion of steel rebars, concrete becomes a dependable and long-lasting construction material capable of withstanding various loads and environmental conditions.
Q:
There are several factors that can contribute to the premature corrosion of steel rebars. 1. Exposure to moisture: One of the primary causes of rebar corrosion is the presence of moisture. When steel rebars are exposed to water or high humidity levels for extended periods, it can lead to the formation of rust or oxidation on the surface of the rebar. 2. Chloride ions: Chloride ions, commonly found in seawater or de-icing salts, can accelerate the corrosion process of steel rebars. These ions can penetrate the concrete cover and come into contact with the rebar, causing it to corrode at a faster rate. 3. Carbonation of concrete: Carbonation occurs when carbon dioxide from the atmosphere reacts with the alkaline components of concrete. This process reduces the pH levels, leading to a decrease in the passivating effect of the concrete cover and increasing the likelihood of rebar corrosion. 4. Insufficient concrete cover: Inadequate concrete cover over the rebars can expose them to external elements, such as moisture and chloride ions, leading to accelerated corrosion. Insufficient cover may occur due to poor construction practices or inadequate design specifications. 5. Poor quality of concrete: If the concrete used in construction is of low quality, it may contain impurities or lack proper curing, resulting in an increased permeability of the concrete. This allows harmful substances like moisture and chlorides to penetrate the concrete more easily, leading to premature rebar corrosion. 6. Galvanic corrosion: When dissimilar metals come into contact in the presence of an electrolyte (such as moisture), a galvanic cell can form, resulting in accelerated corrosion. For example, if steel rebars are in contact with aluminum or copper materials, galvanic corrosion can occur. 7. Construction defects: Issues during the construction phase, such as poor workmanship or inadequate protective measures, can contribute to premature rebar corrosion. Examples include inadequate concrete compaction, improper reinforcement placement, or lack of proper waterproofing. To prevent premature corrosion of steel rebars, it is crucial to use high-quality materials, ensure proper concrete cover, employ corrosion-resistant coatings or inhibitors, and implement appropriate construction practices. Regular inspections and maintenance can also help identify and address any potential corrosion issues before they worsen.
Q:
Steel rebars can significantly enhance the vibration control of a structure. By providing additional stiffness and strength, rebars improve the overall structural integrity, reducing vibrations and increasing the structure's resistance to dynamic forces. This increased stiffness helps to limit excessive deflections and damping of vibrations, resulting in improved performance and stability of the structure under dynamic loads. Additionally, steel rebars contribute to the redistribution of forces within the structure, minimizing localized vibrations and preventing potential failure points.
Q:
Steel rebars play a crucial role in the construction of highway overpasses as they provide reinforcement and strength to the concrete structures. They help to distribute the load and stress evenly, ensuring the stability and durability of the overpass. Rebars also help to resist the tensile forces that occur due to heavy traffic and environmental factors, preventing cracks and structural failures. Overall, steel rebars are essential elements that enhance the performance and safety of highway overpasses.
Q:
Yes, steel rebars are highly resistant to fire due to their high melting point and heat conductivity, making them an ideal choice for reinforcing concrete structures in fire-prone areas.
Q:
Yes, steel rebars can be used in nuclear power plant construction. Steel rebars are commonly used in reinforced concrete structures, including those found in nuclear power plants, to provide structural strength and durability. These rebars help reinforce the concrete and enhance the overall integrity and safety of the construction.
