Corrosion Resistant TMT Bar

The Role of TMT Bars in Corrosion-Resistant Construction

corrosion resistant tmt bar

Corrosion, the slow and silent enemy of metal structures, is a concern in construction, particularly for reinforcing bars. Yet, Sigma Griplock’s corrosion-resistant TMT (Thermo-Mechanically Treated) bars emerge as a dependable solution, offering durability and strength while standing tall against rust.

Understanding Corrosion

Corrosion is a natural process, accelerated by environmental factors like moisture and oxygen. In construction, it poses a serious threat, especially in regions with high humidity or near coastlines.

Corrosion Resistance in TMT Bars

TMT bars are a construction staple due to their strength and flexibility. The Thermo-Mechanical Treatment process, involving controlled heating and cooling, enhances their structural properties. The corrosion resistance in TMT bars is primarily due to the protective oxide layers formed during this process.
