TMT steel bars are becoming popular for their superior tensile strength, ductility, and corrosion resistance. However, they must be properly stored and handled as they are vulnerable to damage and cracking. The damages may adversely impact the strength and performance of the structure. So, it is important that the builders pay close attention to ensure that the TMT steel bars are properly stored and handled, right from unloading, stacking, and cutting to fabrication and welding.
In this article, we have extensively covered the procedure for the storage and handling of Thermo mechanically treated bars at the construction site. Read the blog to learn the best practices for TMT steel bar storage.
How to store TMT steel bars safely?
The following are some of the best practices for storing construction TMT bars safely at the site.
1. Choosing the right location
The right location is the first priority for storing construction materials. Exposing the steel bars to heat, rain, humidity, etc., increases the chance of rust and corrosion. When they are stored outside at the construction site, they are exposed to frequent temperature and weather changes. This causes the material to contract/expand with time.
So, they must be stored in a dry area away from direct exposure to sunlight. Also, TMT bars must not be stored in areas near water bodies and those vulnerable to moisture. Storing outdoors may also expose the Thermo mechanically treated bars to contaminants and dirt, which may impact the strength of the bars. So, the storage area must be free of chemicals and contaminants.
Experts advise placing TMT bars above the wooden pellets to help pull them up above the soil and ground. This helps prevent rusting due to moisture from the ground.
2. Add coating for protection when stored outside
If there is no option for indoor storage, then the TMT steel bars must be covered with a protective coating to shield them from adverse weather. Proper ventilation must also be ensured. Anti-corrosive coatings are available, and applying them over the steel bars helps create a layer between the steel bar and moisture from the ground. This protects the steel bars against corrosion and rust.
When choosing a protective coating for TMT steel bars storage, you must choose one that goes well with steel and is appropriate for the weather conditions prevailing in your region. You must also check and coat periodically based on the environment in which the steel bars are stored.
3. Safe loading
When it comes to handling TMT steel bars, utmost care must be taken to ensure the safety of the workers involved. The following are a few tips you may follow:
- Use cranes and other heavy-lifting equipment while loading or moving steel bars.
- Do not drag the bars on the ground as it may damage the structure.
- All the workers must be trained to handle the loading operations without accidents.
4. Stacked storage
The TMT steel bars must be piled up and stacked properly based on the grades and sizes of TMT bars. This helps organize the storage area and makes it easy to handle them. It also helps avoid confusion.
The steel bars must not be piled up in huge numbers as it may lead to bending. In that case, using separators helps develop a space between the stack while ensuring proper ventilation. This minimises the exposure to moisture and prevents rusting and corrosion.
5. Frequent inspection
The TMT bars must be inspected at regular intervals. Doing so helps prevent damages early. While inspecting, look for damage, rust, or deformation. If you find any problems, they must be treated right away. If you see rust, then clean the area and apply a protective coating. The damages must be recorded and followed up periodically.
6. Prevent bending of TMT bars
Bending the TMT bars during installation impacts the strength of the TMT bars. Follow these practices while handling the TMT bars:
- Do not bend the bars. Always keep them in a straight position.
- Do not exert any force that may lead to bending.
- In case adjustments are needed, using equipment and appropriate machines.
- Train workers to handle the TMT bars without bending and damage.
7. First in First out principle
The TMT bars must be stocked and handled following the FIFO (First in, First Out) principle. The oldest stock should be used first as it helps prevent damage and deterioration from prolonged storage.
Wrapping up
The steel bars must be stacked and organized properly. While loading, they must be handled with care and should not be dragged on the ground. The steel bars should not be placed directly on the ground as the moisture from the soil may lead to rust and corrosion. So, they must be properly stored and cautiously handled.
TMT steel bars increase the core strength of the building and protect it from cracking. They are increasingly preferred because of their greater tensile strength and ductility. However, they must be handled safely and stored properly. Otherwise, they may be damaged and contaminated, which in turn impacts their core properties.

FAQs
1. Where should steel bars be stored?
The steel bars must be stored in a location away from direct sunlight and insulated from changing temperatures. They must be stored above the ground and insulated by a wooden pallet below. In case there is no indoor option, experts advise using a protective coating to protect the damages from moisture.
2. How should the steel bars be stacked?
The steel bars must be stacked horizontally, leaving ample space between the bundles. They must be organised by grade and size of TMT bars, so they can be accessed easily.
