Corrosion resistance TMT bars are made of high-grade steel that is specially treated to increase its resistance to corrosion and rust. They are designed to withstand harsh weather conditions, including exposure to acid rain, salt spray and extreme temperature fluctuations. These bars are ideal for outdoor structures such as bridges, buildings, and other structures that are exposed to these types of harsh conditions. The corrosion-resistant properties of these bars make them a great choice for a variety of applications.
