TMX or TMT which is best for house construction
steel is one of the most commonly used materials in commercial and industrial building construction.
Structural steel differs from concrete in its attributed compressive strength as well as tensile strength. Strength – Having high strength, stiffness, toughness, and ductile properties, structural
In this Article i am going to tell you which steel is Best for house construction .With the help of Difference of TmX and TmT I can elobrate the best in it :-
TMT bars
TMT bars are Thermo Mechanically Treated bars which are used as reinforcement bars. TMT bars are generally hot-rolled from steel billets and are subjected to a programmable logic controller (P.L.C.) for the thermo-mechanical treatment. They are used for civil constructions purpose.
TMX bars
TMX steel is a High quality TMT bar.Thermax technology is used for this. Thermex bars, unlike CTD bars, have a proven record resisting loss of strength at high temperatures as experienced during fires.
TMX bars are better than TMT bars but from cost point of view, where you do not need fire proof structures like water tank, compound walls etc, TMT bars should be consider.
How Tmx Steel Bars Are Superior Than Tmt Steel Bars
TMX (Thermax powered) steel is a high quality TMT steel bar, have a definite advantage over TMT Bars in terms of superior properties, such as weldability, strength, are more ductile and tensile. These bars meet the highest quality standards worldwide. Moreover TMX steel bars have proven more heat resistance especially during fires, which adds on to the strength and keeps the whole structure safe. That’s why TMX bars are termed as a new generation high strength steel.
Thermex Technology
THERMEX, from HSE GERMANY and TEMPCORE from CRM BELGIUM are the two patented technologies to manufacture thermo processed bars worldwide, of which THERMEX Bars are having 80% of the market in India and a 60% market share worldwide. The Thermex Cooling Technology involves subjecting the bar to predetermined quantity of high-pressure water after the last rolling mill stand. This treatment converts the bar surface to a hardened structure.
This results in a unique structure of tempered marten site in the peripheral zone and a fine grain ferrite-pearlite at the central zone.
Better Ribs – The strength of a construction depends on the quality of TMX bars used in it and most importantly the ribs on these bars. TMX Bars bear very prominent ribs that give them improved adhesiveness, and provide the construction with higher strength and a longer life
Chemical Composition: Unlike TMT bars, TMX bars can withstand high temperatures as experienced during fires.
Higher Elongation – TMX Steel Bars possess an elongation ranging from 16% to 23%, compared to standard industry norms of 14.5%.
Excellent Straightness – With the help of high-end rolling techniques and a Special Rotary Flying Shear, perfect straightness is ensured. TMX Bars are produced in straight length unlike many mills, which produce the rebars in coil form.
Earthquake Resistance – The enhanced elongation translates into greater flexibility, which gives the resultant structure improved resistance during earthquakes and other natural calamities.
Higher Weldability –TMX Bars are produced only from MS Billets that make the bars free of impurities and balanced in chemical composition. This gives the bars an edge over other bars in terms of superior welding and forming stronger bonds.
Corrosion Resistance: More corrosion resistant than CTD bars. Cold working involved in CTD bars leads to surface stresses and consequent higher rate of corrosion – and, the protective scale layer falls off during twisting The Thermex process basically inhibits rate of scale formation and no cold working is involved.
