FAQ:
Q1: Can stainless steel rust?
A1: 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.
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.

Bend Test: This test evaluates the rebars' ability to withstand bending without cracking or breaking. The steel rebar is bent to a specific angle and checked for any visible cracks or fractures. 3. Chemical Composition Analysis: This test determines the chemical composition of the steel rebars, ensuring they meet the required standards. It involves analyzing the levels of carbon, manganese, phosphorus, sulfur, and other elements present in the rebar. 4. Visual Inspection: This test involves a visual examination of the rebars to ensure they are free from surface defects, such as cracks, splits, or any other irregularities that may affect their structural integrity. 5. Dimensional Inspection: This test verifies the dimensions and shape of the rebars, checking for any deviations from the specified requirements. It involves measuring the diameter, length, and shape of the rebars using calibrated instruments. 6. Weldability Test: In case the rebars are intended for welding purposes, a weldability test is performed to assess their suitability for welding. This test involves welding the rebars and evaluating the quality of the weld joint, including factors like strength, porosity, and brittleness. 7. Corrosion Resistance Test: This test determines the rebars' resistance to corrosion, which is crucial for their long-term durability. It involves subjecting the rebars to accelerated corrosion conditions, such as exposure to corrosive environments or salt spray, and assessing their corrosion resistance. These quality control tests play a vital role in ensuring the quality and reliability of steel rebars used in construction projects. By conducting these tests, manufacturers and inspectors can identify any non-compliant or substandard rebars, ensuring the safety and structural integrity of the buildings and infrastructure where these rebars are used.

By absorbing and distributing the tensile forces that occur within concrete, rebars help prevent cracking and structural failure. In terms of maintenance, the presence of steel rebars can greatly reduce the need for repairs and maintenance activities. Due to their high tensile strength, rebars enhance the structural integrity of a building, making it more resistant to external forces such as seismic activity, wind loads, and heavy loads. This added strength minimizes the likelihood of cracks, deformations, and other structural issues that may require costly repairs. Moreover, steel rebars also contribute to the overall durability of a structure. They are highly resistant to corrosion, which is a significant concern for the maintenance of concrete structures over time. Corrosion of rebars can lead to concrete spalling, cracking, and other forms of deterioration. However, the use of steel rebars with appropriate protective coatings can effectively prevent or minimize the corrosion process, reducing the maintenance requirements associated with corrosion-related issues. Furthermore, steel rebars are relatively easy to inspect and monitor for potential maintenance needs. Regular inspections can identify any signs of corrosion, damage, or misalignment of the rebars. Early detection of such issues allows for timely repairs or remedial actions, preventing further deterioration and extending the lifespan of the structure. In summary, steel rebars positively influence the overall maintenance requirements of a structure. They enhance the structural integrity, durability, and resistance to external forces, reducing the frequency and extent of maintenance activities. Additionally, their corrosion resistance and ease of inspection contribute to the long-term maintenance and preservation of the structure.
