Technological Marvel
Technological Marvel
Rust Guard TMT Bar is the latest breakthrough in steel with patented rib pattern, ensuring strong grip of concrete in RCC under fusion bonding conditions. A specially researched product from one of the finest producers of steel in India, RustGuard TMT bar is a technological marvel, specially created to provide complete protection against corrosion. It extends life of the construction manifold while providing the best possible strength.
Top Notch Manufacturing Process
Top Notch Manufacturing Process
Rust Guard TMT bar is manufactured by Fusion Bonded technology USA, wherein a metaloplast membrane gets infused with the top molecular layer of the steel body making it chemically neutral to all normal acidic and basic conditions. It acts as an inhibitor to actions of hard water, seals reaction sites and shuts out microporosity. Captain RustGuard TMT bars extend life of the construction manifold, by providing excellent strength to the infrastructure.
Long Life of Structures
Long Life of Structures
Captain RustGuard TMT bars extend life of the construction manifold, by providing excellent strength to the infrastructure. Captain RustGuard TMT bar extends the longevity of structures in harsh, corrosive environments, as it is chemically neutral to all normal acidic and basic conditions, thereby rendering it ideal for large construction projects such as buildings, bridges, flyovers, dams and highways as well as Individual House Builders (IHBs). Latest in the block, it has equal appeal among private and government sectors for constructions.

Fusion Bonded Epoxy TMT Bars have been the skeleton of strength for buildings and bridges around the world. Internationally it has been recognized as a symbol of longevity.

Captain RustGuard

Handling Technique and Advantage

Extended Life of construction
Extended Life of construction
As Captain RustGuard TMT bar completely cuts off oxygen and water in concrete, corrosion becomes impossible, as a result of which the life of constructions increase manifold. It extends the longevity of structures in harsh corrosive environments.
Better Weldability and Stretchability
Better Weldability and Stretchability
High strength and ductility come from the fine grain multiphase composite structure. The metaloplast membrane leads to better stretchability and toughness. Since mechanical properties of the rebar remain unchanged, the inherent strength of the TMT bar is not compromised. Neither the outer surface nor the inner surface is ruptured during bending operations and high thermal stability is maintained. This makes it easy to weld.

600 EQR is made from C-20 billets, which enhances the intrinsic quality of the bar to
withstand load under adverse conditions

Captain 600 EQR can resist upto 600 degree Celsius

Yes, we provide the test report with the consignment


600 EQR is made from C-20 billets, which enhances the intrinsic quality of the bar to withstand load under adverse conditions.

The scientific rib design of Captain 600 EQR provides better gripping for better bonding with concrete.

Captain 600 EQR can resist upto 600 degree Celsius.

Due to low carbon content content, bars can be butt or lap welded using ordinary rutile
coated electrodes without pre or post heat treatment.

Rust Guard TMT bar is called a green revolution in steel and Captain Steel India Ltd
manufactured it first in Eastern India.

It is called Rust Guard as this TMT bar provides complete protection from Rust and corrosion due to
the epoxy coating on the bar.

Epoxy coatings cure, whereas paint dries. In addition, when 100 percent solid epoxy
coatings are used, the surface becomes hard and durable, making it highly resistant to
things like chemicals, abrasions, impact, oil and grease, and stains.

No the green colour is not hand painted. It is a fusion bonded epoxy coating on the TMT bar, done
by high end machines. Fusion bonded epoxy is basically 100% solid ground fused powder particles
which when heated melt to form a continuous film, the metaloplast membrane. This membrane
being non-penetrative protects the steel from attack of oxygen and water molecules and provides
protection from rust and corrosion.

The rib design of Rust Guard TMT bar ensure strong grip with concrete in RCC under fusion bonding
conditions. So Rust guard doesn’t slip with concrete, rather has a very strong grip with concrete.

Yes Rust Guard TMT bars can be welded. After welding, patch up coating must be applied on the cut
area. Patch up coating is provided complimentary by Captain Steel on every purchase.

Yes Rust Guard TMT bars are flexible and can be bended.

Rust Guard TMT bars conforms with BIS IS 13620 : 1993 specifications

No, please use cutting machine or hacksaw blade to cut Rust Guard TMT bars.

Please use mandrel for bending Rust Guard TMT bars.

Rust guard TMT bars are manufactured by the following steps:
a. Surface preparation by shot blasting process
b. Heating of rebars (upto 240 degree Celsius) by Induction heating
c. Epoxy coating on rebars
d. Quenching on rebars
e. Testing of the product
