                     TMT Bars vs. Galvanized 
Sheets: Choosing the Best 
Roofing Steel
Selecting the right material is crucial for building a strong and 
durable roof. This presentation explores the differences between 
TMT Bars and Galvanized Sheets, their unique properties, 
advantages, and applications to help you make an informed 
decision for your roofing needs.
What Are TMT Bars?
Thermo Mechanically Key Properties
Treated Bars
Superior ductility, 
High-strength weldability, and corrosion 
reinforcement bars widely resistance
used in construction
Manufacturing Process
Specialized heat treatment that makes them robust while 
maintaining flexibility
What Are Galvanized Sheets?
Galvanized sheets are steel sheets coated with a layer of zinc 
to protect against corrosion. They are:
• Lightweight and cost-effective
• Easy to install with a shiny, polished finish
• Popular for roofing in residential and industrial buildings
The zinc coating acts as a protective barrier against rust, 
ensuring longevity and reducing maintenance costs.
