TMT Bars, due to its Thermo- mechanical treatment are very highly rust and corrosion resistant and is best suited in the humid and coastal areas
With a very controlled manufacturing process, we produce this superior quality of TMT bars off following diameters: 6mm, 8 mm, 10mm, 12mm, 16mm, 20mm, and 25mm.
Sotrafer TMT bars are extremely fatigue resistant and display enhanced physical features due to the specific chemical composition. The intensified properties of strength and ductility reinforce the strong bonding of the rods with concrete during constructions.
Sotrafer TMT bars in brand name “SOTRA TMT” is available with below mentioned specifications in accordance of SANS 920:2011 Edition 2.3:

TMT Bars are much superior to conventional TOR Steel by virtue of their various engineering properties and can be used for Residential Buildings, Bridges, Drums, Industrial Establishment and all types of concrete reinforcement purposes.
For millennia people have believed that the element that gives a structure its strength is cement. This is partly true. The greater part of the answer is rebar – the twisted, lengths of metal that stick out from rising buildings
