What tests are performed by TMT bar manufacturers to assure their quality?

 

                                                                    

With the changing times, construction work is also growing rapidly around us, whether it be a commercial or residential project. The quality of construction mainly depends on the materials utilized for making it. The quality of the building materials decides the durability and strength of the building. Therefore, it is very important to choose the best quality materials only. TMT bars play a good role in making any building and therefore the TMT bars used in construction should be of the best quality.

TMT bars come in different grades such as Fe500, Fe500D, and Fe550, the numbers mainly signify the yield strength. Wondering about how TMT bar manufacturers ensure their quality? There are specific tests which ensure the mechanical properties of these bars.

Tensile Test

This test is crucial for assessing how TMT bars respond to applied force. According to IS 1786 specifications, TMT bars with a capacity of 32 mm can be tested without the need for a UTM machine which is used to measure the reinforcement bars. However, above 32 mm you will need the machine to test.

Bend and rebend test

In many cases, you will find that TMT bars are being deformed. This happens because the materials are being handled incorrectly. You can perform a bend test by bending the bars manually. Quality TMT bars will bend easily without showing any sign of cracks. While the brittle ones will crack easily when you bend them which identifies the poor quality.

Yield test

The yield stress test is performed to check up to which level the TMT bars can take the stress. It tests the approx. elasticity limit of the metal. When the load is applied to the metal and does not exceed the yield point, it will return to its original shape after the stress is removed.

Chemical test

This test is mainly performed to find the percentage of carbon, copper, phosphorous, manganese, chromium, and sulphur with the help of a spectrometer. This test reveals the flaws and level of impurities present in the steel.
