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.

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, helping to prevent cracking and improve overall structural integrity.

Q: What are the different types of steel rebars used in tunneling?: The different types of steel rebars commonly used in tunneling include carbon steel rebars, epoxy-coated rebars, stainless steel rebars, and galvanized rebars. These rebars are chosen based on their specific properties and characteristics, such as strength, corrosion resistance, and durability, to ensure the tunnel structure's integrity and longevity.

Q: How are steel rebars protected against corrosion?: Steel rebars are protected against corrosion through various methods, such as applying protective coatings, using corrosion inhibitors, and employing cathodic protection systems. These measures help prevent the contact of rebars with moisture and oxygen, which are the main contributors to corrosion.

Q: What are the guidelines for using steel rebars in pre-stressed or post-tensioned concrete elements?: The guidelines for using steel rebars in pre-stressed or post-tensioned concrete elements include ensuring the rebars meet the required specifications and standards for strength, size, and corrosion resistance. They should be properly anchored and positioned within the concrete element according to the design specifications. Additionally, care should be taken to avoid damaging or stressing the rebars during the construction process, and proper curing and protection measures should be implemented to prevent corrosion and ensure the longevity of the structure.

Q: Can steel rebars be used in structures with high resistance to abrasion?: Structures that require high resistance to abrasion can benefit from the use of steel rebars. Reinforced concrete structures often incorporate steel rebars to enhance their strength and durability. The specific steel chosen for rebars is known for its exceptional tensile strength and ability to withstand various environmental conditions. While the rebars themselves may not possess inherent resistance to abrasion, the concrete surrounding them offers protection against this. When properly designed and constructed, reinforced concrete structures with steel rebars can endure significant levels of abrasion without compromising their structural integrity. For areas with particularly harsh abrasion or corrosive environments, epoxy-coated rebars can be employed to provide an additional layer of protection against both abrasion and corrosion.

Q: How do steel rebars affect the durability of concrete in freeze-thaw cycles?: Steel rebars can significantly improve the durability of concrete in freeze-thaw cycles. Due to their high tensile strength and ability to resist corrosion, rebars enhance the structural integrity of concrete by providing reinforcement and preventing cracking. By effectively distributing the tensile stresses caused by freeze-thaw cycles, steel rebars help to maintain the overall stability and longevity of the concrete structure.

Q: Can steel rebars be painted or coated?: Steel rebars can indeed be painted or coated, a common practice in construction and engineering for protecting against corrosion and enhancing their appearance. The procedure involves applying a layer of paint or coating substance onto the rebars' surface. This protective layer acts as a barrier, preventing moisture and other corrosive elements from reaching the steel, thereby extending the rebars' lifespan. Furthermore, painting or coating the rebars aids in distinguishing them from other construction materials or facilitating color-coded identification. It is crucial to utilize top-notch paint or coating materials specifically formulated for steel applications to ensure adequate adhesion and durability.

Q: How do steel rebars contribute to the ductility of a structure?: Steel rebars contribute to the ductility of a structure by providing reinforcement and increasing its ability to withstand deformation without fracturing. The presence of rebars allows concrete to handle higher tensile forces, preventing brittle failure and enhancing the overall strength and flexibility of the structure.

Q: What is the role of steel rebars in preventing structural vibrations?: Steel rebars play a crucial role in preventing structural vibrations by providing reinforcement and stability to concrete structures. The rebars, which are embedded within the concrete, enhance the overall strength and rigidity of the structure, making it more resistant to vibrations caused by external factors such as wind, earthquakes, or heavy machinery. The presence of steel rebars helps to distribute and dissipate the energy generated during vibrations, reducing their amplitude and preventing potential structural damage or collapse.
