What makes them resistant to corrosion

Corrosion is the enemy of structures. As the name suggests the TMT bars that can evade corrosion are called so. The corrosion resistant TMT bars are made up of a layer of epoxy coating to make them resistant to corrosion. The epoxy coating in the bars acts as a protective layer to anything that may cause the bars to erode. Usually, they bring air, water and some kinds of salts. When the building surfaces come in contact with the moisture or humidity it starts to corrode the surface then slowly reaches the TMT bars if these bars are made up of corrosion resistant TMT bars, the steels hold everything together without giving in. In the case of normal reinforcement, the bar corrodes and building begins to splay.

Manufacture of Corrosion resistant TMT bars

Corrosion resistant TMT bars are the type of bars specifically used in areas with higher moisture and humidity in the atmosphere. Manufacture of the corrosion resistant TMT bars differs from the normal TMT bars, in the former, there is an additional epoxy coating which makes them resistant to corrosion. Due to this the corrosion resistant TMT bars are highly sorted out and at the same time, they are environment friendly. Due to the differences in the manufacturing process, the corrosion resistant has an extra life and is more flexible than normal steel bars.
How corrosion resistant TMT bars works over normal steel bars
Normal non-reinforced steel corrodes generally if it comes in contact with any of the reagents, include moisture, rain, humidity, etc. When this happens, the steel starts to wear off and spalls the building. Reinforced steel or epoxy coated corrosion resistant steel bars when placed in concrete it develops a passive oxide film that prevents it from corrosion. So, when the TMT bars come in contact with moist air, the coating formed over them acts as a shield, thus not forming rust.

Advantages of corrosion resistant TMT bars

The corrosion resistant TMT bars have a number of advantages over normal steel bars and an exceptional reason being that they withstand corrosion and ensure that the structure lasts long. The corrosion resistant TMT bars are used in underwater construction, bridges, and sewer lines building. So that they do not corrode or show signs of damage. Where the normal steel bars are not recommended in areas with damp temperature and weather conditions.

Another reason is that some of the constructors choose this type of steel even in non-humid conditions as a fail-safe to make sure the structure or housing lasts a long time. In the case of normal steel bars, we cannot have that, because as time progresses the steel comes in contact with the atmospheric elements and thus causes a chemical reaction and thus corroding the steel in the process, which weakens the building and initiates the formation of cracks on the surface. So as a result, the structures with epoxy- coated steels last longer.

The corrosion resistant epoxy coated TMT bars are also low maintenance and offer better flexibility to the bars. This decreases the labor costs for the maintenance of the steel bars compared to normal black steel. That’s a double win there.

And of the major concerns for the construction companies and also the TMT bar Manufacturers is that the end results are eco-friendly and these corrosion resistant TMT bars are on the green side.

The little extra money in these bars pays well in times of a natural disaster and the structure only has minimal damage then opting for a normal bar and the building enduring major damage.

The addition of copper to the manufacturing of these bars gives them a higher corrosion resistance, long-lasting, and also higher flexibility over the normal steel bars.

These are the advantages of corrosion resistant TMT bars over other TMT bars, this also the reason why most of the engineers and builders prefer them even if it is a little pricey and also why the TMT bar Manufacturers also build super strong TMT bars. We want everything to last long and we are not interested in investing anything that is short-lived. So, the TMT bar Manufacturers are always looking for a way to enhance the process.
