When we talk about building a safe, long-lasting structure, choosing the right TMT bar becomes as important as cement or design. One major factor many builders rely on is ISI Certification — a clear sign that the steel meets required quality, strength and manufacturing standards.

I’m starting this thread to help everyone share their experiences and opinions on which ISI-certified best TMT bar brands are most reliable.

🔍 Why ISI Certification Matters

✔ Ensures strength and quality standards
✔ Reduces risk of brittle failure
✔ Helps in seismic and load-bearing safety
✔ Protects against low-grade or counterfeit steel

SEL Tiger TMT (if someone wants strong, flexible, reliable steel for construction)

🧾 What to Check Before Buying

Verify ISI/BIS license number on the TMT bar

Check grade (Fe-500, Fe-500D, Fe-550D based on your structural need)

Ensure rib pattern is uniform & weight is accurate

Never buy purely on lowest price — quality matters more
