Here we will tell you about the main differences between primary and secondary TMT bars in brief points.
Primary TMT Bars
Raw Material: Primary TMT Bars are prepared from virgin iron ore.
Manufacturing Process: Primary TMT Bars undergo a controlled heating and cooling process during manufacturing.
Properties: The steel of Primary TMT Bars has exceptional strength, ductility and durability.
Recommended Use: Primary TMT Bars are used for critical applications where strength and reliability are required.
Strength: Primary TMT Bars have high tensile strength.
Concrete Bonding: These TMT Bars have excellent bonding with concrete.
Resistance: These TMT Bars have remarkable corrosion resistance thus providing building protection for many years without rusting.
Quality and Performance: These TMT Bars are generally considered to be the best in terms of quality and performance.
Secondary TMT Bars
Raw Material: Secondary TMT Bars are manufactured from recycled scrap steel.
Manufacturing Process: Undergoes the same thermo-mechanical treatment process as primary TMT bars.
Properties: These TMT Bars have good strength and other desirable properties.
Recommended Use: These TMT Bars are considered suitable for specific requirements or budget-related projects as these bars are economical.
Strength: The strength of secondary TMT bars is equal to that of primary TMT bars.
Concrete Bonding: Secondary TMT Bars have satisfactory bonding with concrete.
Resistance: Generally exhibits corrosion resistance but has less resistance than primary TMT bars.
Quality and Performance: Secondary TMT Bars are considered a step down from Primary TMT Bars in terms of overall quality and performance.
Choosing Between Primary and Secondary TMT Bars
Type of Project: Primary TMT Bar is recommended for large and critical construction projects, while Secondary TMT Bar is advised for projects with specific requirements or low budget.
Strength and Reliability: If one does not want to compromise on strength and reliability then Primary TMT Bar should be the preferred choice for them.
Budgetary Considerations: If there is a budget constraint for construction, a secondary TMT bar may be a viable option.
Understanding the points above will help you to make a decision based on the specific requirements of your construction project.
