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.

Q2: How many tons of steel products could be loaded in containers?

A2: 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.

Q3: what is the difference between actual weight and theoretical weight?

A3: All the section steel has two weights: actual weight and theoretical weight. Actual weight is the weighing out when the product delivered from the mill. Theoretical weight is calculated by pieces. The invoice can be based on each of them as your request.

Q: Are steel rebars suitable for reinforcement in swimming pools?: Yes, steel rebars are suitable for reinforcement in swimming pools.

Q: What is the impact of steel rebars on the overall carbon footprint of a construction project?: Steel rebars have a significant impact on the overall carbon footprint of a construction project. As a key component in reinforced concrete structures, the production of steel rebars involves high energy consumption and emissions of greenhouse gases, contributing to the project's carbon footprint. However, steel rebars offer durability and strength, reducing the need for frequent repairs or replacements, which can offset their initial carbon emissions over the lifespan of the structure. Additionally, using recycled steel rebars can further minimize the carbon footprint by reducing the energy and emissions associated with the production of new steel.

Q: What is the lifespan of steel rebars in a corrosive environment?: The lifespan of steel rebars in a corrosive environment can vary depending on several factors such as the severity of the corrosive environment, the quality of the steel used, and the presence of protective measures like coatings or cathodic protection. However, on average, steel rebars can last anywhere from 20 to 50 years in a corrosive environment before significant corrosion damage occurs.

Q: Can steel rebars be used in marine construction projects?: Yes, steel rebars can be used in marine construction projects. They are commonly used for reinforcing concrete structures in marine environments due to their high strength, durability, and resistance to corrosion. However, proper protective measures such as coating or stainless steel rebars should be used to enhance their resistance against saltwater and prevent corrosion.

Q: How are steel rebars installed in concrete slabs?: Steel rebars are typically installed in concrete slabs by first determining the required size, spacing, and layout of the rebars as per structural design requirements. The rebars are then positioned and supported using chairs or spacers to ensure proper concrete cover. Once in place, the rebars are tied together using wire or mechanical connectors to form a reinforcing mesh. Finally, the concrete is poured and allowed to cure, effectively embedding the rebars within the slab to provide added strength and durability.

Q: How do steel rebars affect the electrical conductivity of a structure?: Steel rebars have a minimal effect on the electrical conductivity of a structure. While steel is a conductor of electricity, the presence of rebars in concrete does not significantly enhance or impair the overall electrical conductivity of the structure.

Q: What is the typical weight per meter of a steel rebar?: The typical weight per meter of a steel rebar can vary depending on the diameter and thickness of the rebar. However, on average, a steel rebar weighs around 0.75 kilograms per meter.

Q: How are steel rebars tested for quality and strength?: Quality and strength of steel rebars are assessed through a series of standardized tests, ensuring adherence to required standards and ability to withstand anticipated loads and stresses. A primary test is the Tensile Test, which measures the maximum stress a rebar can endure before breaking. A sample rebar is pulled until it fractures, and the force needed to cause this fracture is measured. This test offers valuable data about the rebar's ultimate tensile strength, yield strength, and elongation. Another critical examination is the Bend Test, which evaluates the rebar's ductility and ability to resist breaking when bent. A sample rebar is bent to a specific angle, and any cracks or fractures are closely inspected. If there are no indications of failure, the rebar is considered acceptable. Furthermore, Chemical Analysis is performed to determine the rebar's chemical composition. This test ensures compliance with required chemical composition standards, as variations can impact the rebar's strength and durability. The Dimensional Test is conducted to verify that the rebar meets the specified standards in terms of dimensions, weight, and shape. Deviations from the required measurements can compromise the rebar's structural integrity. Additionally, the rebar's Surface Condition is visually evaluated to identify signs of rust, cracks, or other defects that could affect its performance. Proper surface condition is crucial for ensuring effective bonding with the surrounding concrete. Lastly, certain rebars undergo Non-Destructive Testing, such as ultrasonic testing or magnetic particle inspection, to identify hidden defects or cracks that may not be visible to the naked eye. In conclusion, these testing methods guarantee that steel rebars possess the necessary quality and strength for use in construction projects, providing essential reinforcement for reinforced concrete structures.

Q: What is the difference between steel rebars and FRP rebars?: Construction projects use steel rebars and FRP rebars as reinforcement materials, but they differ in composition and mechanical properties. Steel rebars, made of carbon steel, are known for their strength and durability, making them a reliable choice for reinforcing concrete structures. On the other hand, FRP rebars are composed of fibers embedded in a polymer matrix, such as glass or carbon. This composite material offers advantages over steel rebars. Firstly, FRP rebars are lighter, making them easier to handle and transport, reducing labor and equipment costs. Secondly, FRP rebars do not corrode, unlike steel rebars. Steel rebars are prone to corrosion when exposed to moisture and chemicals, weakening the structure over time. FRP rebars, however, are resistant to rust and corrosion, making them ideal for environments with high humidity, saltwater, or chemical exposure. Additionally, FRP rebars have a high resistance to electromagnetic fields, making them suitable for sensitive areas like hospitals, power plants, or telecommunication facilities, where minimizing electromagnetic interference is crucial. However, FRP rebars have lower tensile strength compared to steel rebars, making them less suitable for heavy-load-bearing structures. Moreover, FRP rebars initially cost more than steel rebars, but their long-term durability and reduced maintenance requirements can offset this expense. In conclusion, the differences between steel rebars and FRP rebars lie in their composition, mechanical properties, and performance in various environmental conditions. Steel rebars offer high tensile strength but are susceptible to corrosion, while FRP rebars are lighter, non-corrosive, and have a high resistance to electromagnetic fields. The choice between the two depends on project requirements, load-bearing needs, and environmental factors.

Q: Can steel rebars rust or corrode over time?: Yes, steel rebars can rust or corrode over time due to exposure to moisture, oxygen, and other environmental factors.
