What are the Top Reasons for Using TMT Bars in Bridge Construction?
Bridges are essential for connecting places and overcoming physical barriers caused due to valleys, rivers etc. These structures need to be strong, stable and aesthetic, with a good deal of flexibility. TMT (Thermo Mechanically Treated) bars are a popular construction material, widely being used today in bridge construction as a type of steel reinforcement. Know the top reasons why these are increasingly being used for making bridges today.
Ensures superior strength
Bridges have to bear a lot of traffic, foot traffic as well as vehicular traffic. Both moving and stationary traffic are borne. TMT steel bars are known for their superior yield strength, which provides bridges with the support and ability to bear load constantly. These manage to keep bridges secure and hold together everything properly.
The unique Thermo-Mechanical Treatment that goes into the production of these bars ensures higher yield strength, better weldability, higher fatigue resistance, ductility and durability. Due to the massive investment involved in building bridges, it is impossible to construct new ones quickly in case of failure of the previous ones. Even maintenance and repair work can be time-consuming and expensive. With the use of superior TMT bars in bridge construction, all these can be minimized as much as possible.
Offers flexibility
Bridges are not only about a lot of strength. These do not need to be only firm and rigid. Rather, these should have enough flexibility, to maintain stability during high winds, thunderstorms, earthquakes etc. These also need to sustain thermal expansion.
Thermo Mechanically Treated bars have a higher level of ductility and can bend without breakage. When used for construction, these allow bridges to sway a little under pressure. This lets bridges absorb stress and not buckle under pressure.
Corrosion-resistant
Corrosion is a continuous threat for bridges, which have to stay exposed to the elements at all seasons. Manufactured uniquely, these are more rust-resistant than standard steel bars. This ensures high structural integrity of bridges in the long-term.
In many areas, especially those that receive higher rainfall or have wetlands or water bodies nearby, a high amount of surrounding moisture can lead to rust issues in bridges. Over time, rusting can weaken the steel and thereby, compromise the stability of bridges. With corrosion-resistant TMT steel bars, this can be prevented.
Forms an excellent mechanical bond
TMT bars can bond much better with concrete due to their ribbed surface. When used for making bridges, these can prevent cracks in the structure by ensuring proper load distribution. Bridges are used every day for connecting communities, daily commutes and transportation purposes.
These need to have exceptional strength to bear constant load and activities. Better bonding of TMT bars with concrete ensures better stability and keeps bridges strong, stable and durable for many years to come.
TMT steel bars from top brands like SRMB satisfy the highest standards of strength and are known to be extremely reliable. These are a favourite of engineers and contractors who are involved with bridge construction projects.
