Steel forms the backbone of any construction project, and TMT bars play a crucial role in ensuring structural integrity. However, many buyers make costly mistakes when purchasing TMT steel bars. Here’s what you need to watch out for:
1. Overlooking Grade Specifications
Not all TMT bars are created equal. Each construction project requires specific grades (Fe 415, Fe 500, Fe 550) based on load-bearing requirements.
Using lower-grade bars to cut costs can compromise your building’s safety. Kairali TMT’s technical team can help you determine the right grade for your specific needs.
2. Focusing Only on Price
While budget matters, making purchase decisions solely based on price often leads to regret. Quality TMT bars, might cost more initially but offer:
- Better yield strength
- Superior corrosion resistance
- Longer lifespan
- Enhanced earthquake resistance
3. Neglecting to Check for ISI Marks
Legitimate TMT bars must carry ISI certification marks. Some manufacturers cut corners by offering non-certified products at lower prices. Always verify the ISI mark and manufacturer’s license number. Every Kairali TMT bar comes with clear ISI markings for easy verification.
4. Improper Size Selection
Using incorrectly sized TMT bars can severely impact construction quality. Common mistakes include:
- Not following architectural specifications
- Mixing different diameters without proper calculation
- Choosing thinner bars to reduce costs
5. Ignoring Surface Quality
Quality TMT bars should have:
- Uniform ribbing patterns
- No surface defects or rust
- Proper straightness
- Clear manufacturer markings
Before purchasing, inspect the bars visually for these characteristics.
6. Not Verifying Manufacturing Date
Fresh TMT bars perform better than older stock. Check manufacturing dates and avoid bars that have been stored for extended periods. Kairali TMT maintains strict inventory management to ensure you receive fresh stock.
7. Skipping Bend Tests
A simple bend test can reveal much about steel quality. Quality TMT bars should:
- Bend without cracking
- Show no surface deformation
- Return to shape without significant deformation
8. Poor Storage Conditions
Even the best TMT bars can deteriorate if stored improperly. Ensure your supplier:
- Stores bars in covered areas
- Keeps them elevated from the ground
- Protects them from moisture and chemicals
The Bottom Line
Quality TMT bars are a long-term investment in your construction’s safety and durability. While it might be tempting to cut corners, the risks far outweigh any short-term savings. Choose reliable manufacturers like Kairali TMT who prioritize quality and offer proper technical support throughout your construction journey.
