TMT bars and Structural Integrity

tmt-bars-structural-integrity-rightsteel

A building in only strong as its structure, this strength allows structures have an operation lifecycle of many years, right up to 200 years.  This operational longevity may seem long when seeing structures which are old than 500 years. The difference here is with respect to cost, the time taken to build these structures and much more metrics related to the construction field. For example, the Taj Mahal took 20 years and 20,000 workers were needed to finish the structure, no doubt the structure is a testament of the structural creativity and the structural integrity, the reason why it still stands. What modern architecture has built these of structures to be made at less cost, safer, and reduced number of workers as well. One of the reasons for this is concrete and the concrete is bonded with TMT bars.

Natural Disasters vs TMT bars

natural-disasters-vs-tmt-bars-rightsteel

India is one of the most disaster-hit countries in the world, India is prone to earthquakes, hurricanes, thunderstorms and floods. Keeping these in minds, the design and constructions of structures have significantly changed in the recent times. Authorities have also laid down strict guidelines for building structures which can withstand many natural disasters, the construction and the real estate sector have followed this guideline to the letter.

In the previous blog, we saw how steel has managed to stay ahead of its competition, in this blog we will discuss in considerable detail about the ability of steel to be flexibility, weldability, and retain the strength. We will also look at some specific shapes of steel which are used in day to day construction projects as well as large-scale projects.

The global construction has chosen steel as their crux for every rising structure, this choice can be been seen from the Burj Khalifa to your own home. Steel has managed to gain the trust of world-famous architects t your neighbourhood friendly architect as well. Steel has managed to establish a presence in residential, commercial, and industrial structures as well. In this blog we will see how steel has managed to capture the trust of engineers and architects across the world, we will come to find some of the lesser-known facts about steel.

Importance of Lugs and Ribs on TMT rods

tmt-rods-right-steel-fe415

Closely looking at TMT bars one can see rings and lines, in this blog we will see what they and their uses. First things first, these rings and lines are called lugs and ribs, these are placed at regular intervals across the TMT bars of all grades. These lugs and ribs are there give a gripping effect in concrete structures, they give traction to concrete overlay on them. The angular placing on the surface gives the concrete a surface which it can cling on to.

Reasons why TMT bars are better than HYSD bars

While TMT stands for ‘Thermo Mechanical Treatment’, the name is basically their process of protection and HYSD means ‘High Yielding Strength Deformed’ which is their main characteristic when compared with other rods. HYSD bars can be further divided into Torsed / twisted steel (TOR Steel Bars) and Cold Twisted Deformed Steel Bars (CTD Steel Bars).

TMT bars and Rust Part 1

Steel has been used for many decades by many civilizations for building structural and engineering purposes, they have continued prove very effective in both land and marine environments due their unique combination of mechanical properties which gives them natural protection against natural variables. Where steel stumbles as the ultimate building block is with its corrosion by various environmental actions. When it comes to modern construction, generally, the concrete mix is reinforced by steel bars in the case of the common RCC structures.

Things to Remember Before Bending TMT bars

Rust

It is expected that in construction there will become unexpected surprises and in one of those many unexpected surprises not many of the same long-term effects as the need to bend TMT bars. Bending TMT bar is a tricky skill, there are some obvious downsides such as broken TMT bars. The long-term negative effects come from the breaking of the protective film from the surface of the TMT bars. These films are coats of special paints which does rust or corrosion to happen. This happens as TMT bars have a strong shell and a soft inner core, while outer shell can withstand rust and corrosion for a long long time as they come prepared with a protective coating.

TMT bars – Environmentally Safe and Secure

Fe415-TMT-steel-rebar-environment-friendly-secure

One might wonder how TMT bars can be a good news for the environment, the fact of the matter is the most TMT bars are made of steel. Steel is the most recycled material on the planet, one of the reasons for it is the fact that recycled steel does not experience any loss in quality or strength. Steel is so popular for recycling, that in the year 2017 more steel was recycled that all the other recyclables combined. When talking pure numbers, just by recycling 1 kg of steel,  it can cause reduction of 2 kgs of greenhouse gases to the atmosphere. Recycling steel also reduces the spread of landfill, as the materials can get reprocessed, thereby saving raw materials.
