TMT Steel or TMX steel is the best bet for house construction. They are the latest generation of reinforcement steel (high-strength and ductile than their predecessors) .
They are graded as Fe415, Fe500 i.e. yield strength of 415 and 500 N/ sq mm respectively . Higher grade are also available
Reason to use TMT Bar :-
Application of TMT Steel rods in constructions has increased over the past few years because of certain peculiar characteristics that they display
TMT steel bars are produced using TEMPCORE technology that provides the bar with strong outcore martensitic steel with a soft inner core, which makes the bars strong and ductile.
TMT Rod ribbing is a responsible bond between the steel rod and concrete. This bond is extremely important to structure integrity because of TMT steel rod bonds with concrete securely, minimizing the chances of cracks occurring in the structures.
While manufacturing a TMT Steel Rod, the TMT steel rod requires to go through a layered cooling period. An inner core of malleable ferrite-pearlite is the resulting process. This gives it its characteristic flexibility, to be moulded into any kind of construction.
TMT Steel bars have different range and variety available in the market for various structural needs. In India, the different grades are available – Fe 415, Fe 500, & Fe 550. TMT bars have a different range of diameters from 6MM to 32MM.
They are of “
- High Strength
- Higher elongation (which makes it safe for earthquake-prone areas)
- High Bend/ re-bending properties
- Corrosion resistance
- Good weld-ability.
Which Company steel is best for house :-
- TATA Tiscon bars are a reliable name when it comes to residential construction.
- Vizag Steel . It is the Indian Government undertaking.
- SAIL Sail Authority of India ltd.
- Jindal Panther steel It is one of the leading steel manufacturing company.
THE NAKED EYE TEST TO CHECK STEEL ON SHOP :
Simply pick up a bar and check whether the manufacturer’s seal is present on every meter of it. The bars should not look rusty, obviously.
Also, check whether the ends of each bundle of TMT rods is of equal length. Finally, ensure each bar in the bundle has the logo of the TMT bar company, without fail.
