Captain Steel- Corrosion Combat

EPOXY FUSION BOND COATING OF TMT BARS

Recent studies conducted in the construction field have yielded numerous noteworthy advancements, including the application of Epoxy coating on TMT bars. Corrosion and rust pose a significant obstacle within the realm of building. Pollution on the Thermo-Mechanically Treated (TMT) bars results in fissures and spalling, thereby undermining the structural integrity of constructions. In response to this worry, the use of epoxy-coated TMT bars has progressively emerged.

The manufacturing method of epoxy-coated TMT rebars includes fusion bonding, which prevents the coating from delaminating or exposing the underlying rebar surface. Fusion-bonded epoxy refers to the consolidation of solid ground powder particles that, upon heating, undergo a melting process and subsequently establish a cohesive and uninterrupted film. The method referred to is a process originating from the United States in which a film or megaloblast membrane is incorporated into the outermost molecular layer of the steel body of the TMT rebar. The method renders the TMT chemically inert under both acidic and primary conditions often encountered in regular circumstances.

Captain Steel has played a pioneering role in introducing the epoxy-coated TMT bar known as Captain Rustguard in the eastern region of India. Epoxy-coated Rust Guard, a prominent offering by Captain Steel, has garnered significant interest from both public and private entities involved in the construction of various infrastructure projects such as buildings, bridges, flyovers, dams, and individual residential builders. The megaloblast membrane of Captain RustGuard is impermeable, protecting the steel against the corrosion caused by oxygen and water molecules. The rebar products manufactured by Captain RustGuard exhibit enhanced weldability and stretchability characteristics, rendering them a highly favorable option for building applications.

The product is produced in advanced integrated facilities operated by Captain Steel, guaranteeing stringent quality control measures.

The RustGuard TMT bars exhibit notable thermal stability and possess commendable resistance against seismic activity, rendering them well-suited for deployment in various geographical zones. Additionally, this TMT bar displays a high level of convenience in terms of storage. The prevention of rebar oxidation ensures that the bars remain entirely free from corrosion, even when kept for extended durations. In addition, Captain RustGuard is subjected to a series of rigorous quality assessments within the manufacturing facility.

Among the various tests conducted, many have significance, including the continuity of coating or holiday test, coating thickness test, bend test, resistance to applied voltage test, impact test, and Knoop hardness test. These tests collectively contribute to the exceptional quality and adherence to the IS 13620:1993 standard, establishing its status as a world-class product. Fusion-bonded epoxy-coated reinforcement bars are an innovative and forward-thinking product. This product exhibits long-term durability and little maintenance requirements, ensuring its sustained presence in the market for an extended period.

WHAT IS EPOXY FUSION BOND COATING?

EPOXY FUSION BOND Coating stands as a groundbreaking solution in construction, offering unparalleled protection to TMT Bars against the detrimental effects of corrosion. By employing this advanced coating technique, the longevity and durability of TMT Bars are substantially enhanced. But the advantages don't stop there; the concrete in which these bars are embedded also benefits. With the reduction of ion passivation, the overall life of the concrete is increased, minimizing degradation and wear over time. In essence, the EPOXY FUSION BOND Coating not only fortifies the structural strength of individual TMT Bars but also ensures the lasting resilience of the concrete structures they support.
