Fusion bonded epoxy coated reinforcing bars IS 13620:1993

Fusion bonded epoxy coated reinforcing bars (FBE rebars) are used to enhance the durability and longevity of concrete structures by providing superior corrosion resistance. These rebars are coated with a layer of epoxy resin, which is applied through a fusion bonding process, creating a strong, protective barrier against moisture, chemicals, and other corrosive elements. This coating prevents rust and deterioration of the steel reinforcement, thereby maintaining the structural integrity of the concrete over time. FBE rebars are particularly valuable in harsh environments such as coastal areas, industrial settings, and regions with high humidity or exposure to de-icing salts, ensuring the resilience and safety of bridges, highways, buildings, and other critical infrastructure projects.

Importance of BIS Certification

BIS certification is necessary for fusion bonded epoxy coated reinforcing bars to ensure they meet the stringent quality and safety standards established by the Bureau of Indian Standards. This certification guarantees that the rebars possess the required properties for effective corrosion resistance, durability, and structural integrity essential for their use in concrete reinforcement. By adhering to BIS standards, manufacturers can ensure that the epoxy coating is applied correctly and consistently, providing reliable protection against moisture and chemical exposure

Compliance with BIS certification fosters consumer confidence, ensures regulatory alignment, and supports the construction of high-quality, resilient infrastructure projects, thereby enhancing the safety and longevity of buildings, bridges, and other critical structures.

Indian Standard IS 13620:1993

As per the latest Quality Control Order (QCO) issued by the Ministry of Steel, Government of India, on 5th February 2024, fusion bonded epoxy coated reinforcing bars must adhere to the Indian Standard IS 13620:1993. This standard ensures that these reinforcing bars meet essential quality and safety criteria, including the proper application of the epoxy coating, which provides critical corrosion resistance and durability. Compliance with IS 13620:1993 guarantees that the bars are manufactured to precise specifications, ensuring their reliability and performance in reinforcing concrete structures. Adherence to this standard is crucial for manufacturers to align with regulatory guidelines, maintain product consistency, and foster consumer trust in the quality and safety of construction materials.
