Modern constructions demand superior-quality TMT bars for strength and durability. The durability of any construction depends on many factors, including corrosion resistance. Corrosion is a permanent concern in the construction field, especially in coastal areas and humid weather conditions. TMT bars will wear out due to corrosion over time if not made with corrosion resistant steel. The market is flooded with TMT bars; however, choosing the right corrosion-resistant TMT bar is difficult. This article will help you choose the right corrosion resistant steel bars for your construction.
Corrosion or rust forms when the steel comes in contact with moisture, salt, the environmental pH, high temperature, some natural gases, etc. The rust deposition will loosen the concrete grip and start forming cracks. The construction may deform and collapse in the long run due to corrosion formation. In such cases, repairing also becomes difficult and expensive. Investing in a good corrosion resistant steel will increase the lifespan of the building and ensure your safety.
Corrosion erodes the TMT bars, and the construction slowly and silently over time if you do not choose the right corrosion resistant steel for your construction. Please consider the following points while choosing TMT bars for construction.
Firstly, discuss the kind of TMT bars the project needs with your engineer. Such as, how much load-bearing capacity and ductility the TMT bars need to have to build the project.
As we discussed earlier, the environmental factors are the most impactful reason for corrosion. Check the kind of environmental factors your construction needs to face. Several types of corrosion resistant steel TMT bars are available in the market. Choose according to the level of corrosion resistance you need.
Before deciding on the TMT bar, you must check the raw materials they use as components and the process they follow to make the corrosion resistant steel. For example, some TMT bar manufacturers change the composition of the steel by mixing it with nickel and other metals to make it corrosion resistant. Some, on the other hand, use an anti-corrosion coating on the surface.
The TMT bar you are buying must be manufactured according to the standards set by the Govt. to ensure your safety. To be sure about the quality, the corrosion resistant steel bar must have the BIS and ISO certifications, the two most vital certifications in India.
Strength is the main reason TMT bars were invented and used in construction. So, you must check the yield strength of the TMT bars.
Besides corrosion resistance, ductility and weldability are also important. Ductility ensures the bar is capable of handling pressure without breaking the structure. Weldability will help you in achieving seamless and strong welded joints.
The upfront cost of corrosion resistant steel or stainless steel could be high, but low maintenance and repair costs make it a good choice for the long run. While comparing the costs of TMT bars, always consider the upfront and maintenance costs.
Stainless Steel: This is an alloy made with a minimum of 10.5% chromium, which builds an oxide layer on the surface to prevent corrosion.
Weathering Steel (Corten): This steel comes with a protective rust-like layer that helps resist further corrosion.
Galvanized Steel: This is a carbon steel coated with a layer of zinc. This layer makes it excellent corrosion resistant and can be used in heavy corrosion-prone areas.
Duplex Stainless Steel: It is made by combining features of austenitic and ferritic stainless steels. Due to its excellent corrosion resistance, it is used in the chemical, oil, and gas industries.
Since environmental factors such as humidity, salinity, and pollution are unavoidable in most cases, choosing the right corrosion resistant TMT bar is significant for the long-term safety and durability of your construction. Fortunately, innovations in the TMT industries have produced highly durable and corrosion-resistant steel options to cater to the diversified needs of projects.
