TMT steel is the most popularly used steel bars today because of its better elongation, better bending strength and high tensile strength. Its quality and popularity makes it one of the most important materials in the Reinforced Cement Concrete (RCC). There are several other factors that a buyer must consider other than the high-strength that it offers. Here is a list of the major factors that will help a buyer understand the purchase they are making, even better.
TMT Steel Bar Grading:
There are grade numbers that are given to the TMT steel bars that are sold in the Indian markets. The numberings like Fe-415, Fe-550 and Fe-500 are marked on the bars to help the buyers and the sellers identify the quality of the steel bars. Higher the grade, higher will be the strength of the TMT Steel bars. When the TMT Steel bars are manufactured using cold twisted technology, the strength provided by the bars is higher and even more flexible.
The elongating ability of the steel is its ductility. More the elongation of the steel better will be the savings. More elongation also means that transportation cost is reduced. Like, Fe 415 steel bars have a higher rate of elongation and this ensures that the bars would last longer.
The ability of the TMT Steel bars to resist corrosion is one main factor that must be considered as it determines the strength and durability of the building. These steel bars are expected to be exposed to moist conditions and face every sort of weather, which is why, it is important that the buyer confirms that the steel is rust-resistance.
When you are purchasing a TMT Steel bar, you need to know how flexible the bar is. It is important for the steel bars that you are using for construction purposes, to be flexible enough for withstanding all harshness and load for a very long period of time. It the steel is not flexible enough, it will not be durable too. The high quality TMT bars usually do not cause any bending or develop cracks on them.
Compare the suppliers:
When you are buying the TMT Steel bars without having any preferred or trusted supplier, you must consider comparing two or more suppliers to get an idea about the TMT steel bars sold in the market, their prices and their qualities. Once you get an idea of the material, you can make a better choice for investing your money on.
