We all know that rust or corrosion is an enemy of steel items. If a steel material develops rust, you would need to get rid of it as early as possible, otherwise the rust will start eating up the steel.
TMT steel bars are known to provide strength to structures, but rusting of steel could degrade its quality by making it weak in strength. This will waste a lot of your money spent on steel. Thus, it is necessary to follow some essential steps that will help prevent the rusting of steel tmt bars.
If you are using metal equipment that is prone to rust development, you must also know the ways rust affects the metal and the ways to avoid it. This blog has everything you would need to know about the possible queries you have related to rusting of steel bars.
Harmful effects of rusting on steel ?
It is common for the iron and steel materials to develop rust on coming in contact with air and water or moisture. Rust weakens the steel by degrading its quality. Such bars cannot withstand high-level stress and thus installing such tmt bars in high-storey buildings would be risky to consider.
Corroded steel metals also develop friction, thus making the metal difficult to move freely and might also make the metal brittle. Another major effect of rust on steel is the poor appearance of the steel metals.
How can rust be prevented on steel tmt bars ?
There are few ways through which rusting of metals could be prevented, despite them being exposed to air and moisture. These are :
1. Galvanizing -
this is a method where a coating of zinc metal is applied on steel as a protective coating to prevent rusting and damage.
2. Painting/ Polishing -
paints create a protective layer over metal objects and prevent moisture from reaching them. Although it is not a sure way to avoid metal from contacting moisture, it can certainly slow down rust.
3. Rust-proofing sprays
it is a corrosion resistant oil polish spray that you can apply on steel materials as a protective layer against rust.
4. Electrochemical Treatment:
in this method, electrical charge is passed which prevents rusting by suppressing electrochemical reactions.
5. Hot dipping:
in this method, the steel bar is dipped inside the jar of hot molten zinc, to obtain a thin coating of the galvanizing metal.
6. Thermo mechanical treatment:
this method to manufacture steel rods is used widely to prevent rusting from steel metals.
Rust can cause serious harm to the steel bars, eventually weakening and damaging the building structures. Thus, it is important to look for ways in which you can prevent this from happening. You can do this by applying any of the above-mentioned ways to tackle rust on steels or instead you can also go for using good quality tmt bars from a reputed tmt bar manufacturer .
1. What is the lifespan of TMT steel?
Ans: TMT steel bars are renowned to last longer than conventional steel bars thanks to their anti-corrosion and anti-rusting properties. The quality of the construction, the materials used, the type of construction, and many other factors affect the actual life duration of the TMT steel.
2. Is TMT steel rust-proof ?
Ans: Yes, TMT bars are known to possess the highest level of rust-proof properties for any steel bar. TMT bars receive these rust resistant abilities from the Thermo mechanical treatment that it goes through during the manufacturing process at the steel factory.
3. What are CRS steel bars ?
Ans: CRS or corrosion resistant steel bars are the steel bars manufactured by an addition of Copper and Chromium to prevent rust and corrosion. Copper is used to plug the pores in the rust.
4. What is the advantage of using CRS (Corrosion resistant steel) rebars?
Ans: Following are the advantages of using CRS :
• Longer life.
• High yield strength coupled with good ductility and bendability.
• No extra precaution required in material handling and transportation.
• No maintenance required during fabrication.
• More suitable underproof workmanship conditions at site.
• No extra precaution during welding.
• Can be bent and re-bent around very small mandrels.
• Fatigue tests show it can be used as reinforcement material in seismic zones.
