Steel bars are made by thermomechanical treatment (TMT). It is better to build with TMT steel bars in order to mitigate the effects of earthquakes and other natural disasters. When buying TMT bars for constructing your building, you must buy from a top-rated TMT steel bar manufacturer. Here we will discuss the different types of TMT steel bars.
Types of TMT Bars Are-
- Fe-415 grade-
Fe 415 is a very ductile and flexible steel TMT bar. It is most ideal for small-scale construction and residential construction. It is also suitable for compact frames that are easy to manufacture. Your building becomes stronger and earthquake-resistant by using Fe TMT bars.
In mass, iron is mixed with some amount of carbon, sulfur, and phosphorus materials; carbon content is about 0.3%, sulfur content is about 0.06%, phosphorus content is about 0.06%, and S+P is about 0.11%.
- Fe-500 grade-
Many construction projects use Fe 500 grade steel. The other two alternatives for Fe500 are Fe500D and Fe500S. These provide seismic stability and ductility.
Fe 500 could be employed in various residential, commercial, and multi-story structures as they have higher tensile strength and ductility than Fe415, specifically designed to provide stability to high-rise constructions while resisting load. Fe 500 dual-textured TMT bars are one of the most durable and have a distinctive product design.
Carbon – 0.30%, Phosphorous – 0.055%, Sulphur- 0.055%, and S+P – 0.105%. With this composition, you get quite a strength ranging between 500 N/sq.mm and 545N/sq.mm which is considerably higher than the Fe 415 grade.
- Fe-550 grade-
Fe 550 TMT bars are perfect for large-scale industrial projects, power plants, and manufacturing facilities. These TMT bars grip concrete exceptionally well, ensuring long-term weather resistance and safety. TMT steel rods come in ten different diameter sizes, i.e., 8 , 10, 12 , 16 , 20, 25 , 28 , 32 , 36 , and 40 mm rods.
- Fe-600 grade-
Large-scale constructions need Fe600 TMT bars. Fe 600 steel TMT bars have a high tensile strength required for coastal and marine constructions, underground construction, and bridges that span a large distance. Fe 600 is the highest quality TMT bar that any Manufacturer of TMT Bars can manufacture. CHEMICAL COMPOSITION (% MAX)-Carbon – 0.30, Sulphur- 0.04, Phosphorous – 0.04, S+P – 0.075, Minimum Yield Strength – 600 N/sq.mm, Ultimate Tensile Strength – 660N/sq.mm, Elongation (%) – 10, Ration (UTS/YS)- ≥ 1.06. Fe 600 provides more rigidity, lower overall usage, and less steel clogging inside the support.
TMT bars lend superior welding ability, working ability, ductility, and better elongation. It is very cost-effective and increases the pace of construction because TMT bars are incredibly flexible in construction, and they are extremely cost-effective. TMT bars are highly flexible in nature, because of which they do not get cracks even after bending 180 degrees. The steel frames are easy to create and assemble. That is why TMT bar manufacturers find it easy to create and assemble the required steel frames in the manufacturing factory.
