Earthquake, floods, tropical storms, and other natural disasters are daily news in India. To build safe and strong structures in a diverse and geographically challenging country like ours, you need to ensure that the backbone of your RCC structures is STEEL that is tough and resilient. 

The gold standard for steel in RCC construction is CRS TMT bars which accounts for 80% of the market in India and 60% of the global market share.

Here are some of the main benefits of using CRS TMT bar (Sariya)

1. Higher Ductility – The special Themerx quenching & self-tempering process results in a hard outer marten site core while leaving the inner core of ferrite, pearlite

What does this mean for construction and structures?

The ductile core of the CRS TMT bar gives it enhanced elongation and bendability.

During the construction process, this helps the crew to bend the TMT sariya in desired shapes and makes the construction process more manageable.

For the structures, this flexibility results in an enhanced ability to weather earthquakes without losing structural integrity. A structure made from flexible TMT steel is better able to remain intact and standing even during the sideways movement of a seismic event.

2. Anti-Corrosive properties – The CRS manufacturing process also imparts rust-resistant properties to the TMT steel bar. At Moira Sariya, for example, we add copper, nickel, and chrome to the raw materials, which gives the Moira TMT sariyas higher corrosion resistance as compared to ordinary steel bars made from sponge iron.

This makes CRS TMT bars the perfect choice for construction in regions such as coastal areas or for underground facilities, where groundwater salinity, acid particles, or excess moisture in the air is a problem.

3. Cross ribbed pattern for better bonding – All CRS TMT bars come with ribbed patterns which are added to enhance bonding between the concrete and the steel. 

Ordinary sariyas without these ribs and lugs can result in a weakened structure as there is a great chance that during a critical event such as an earthquake the concrete material might lose its grip and slip off.

4. Cost-effective – CRS TMT sariyas offer greater tensile strength and yield strength as compared to ordinary sariya. This means that less steel is required for the construction process – leading to significant savings in the cost of material, storage, and transport.

CRS TMT steel bars are the default choice for almost all large construction projects and rightly so! In fact, the government has made it mandatory for builders and contractors to use TMT bars for all large projects as these bars are inherently earthquake resistant (it should be noted that 60% of the country falls into various seismic zones).

If you want your structure to last till its expected life cycle and beyond, then using the best steel is obligatory, and there is no doubt that CRS TMT bars are the best available in the market!
