The low-quality steel bar impacts the service life of structures or homes, which decreases the strength of structural members.
Construction with a low-quality steel bar ultimately resulted in a financial loss and occasionally harmed the homeowner's safety.
Checking building materials' quality before construction will help you save money and make last-minute compromises.
TMT bars are the backbone of the structure, so checking their quality is mandatory from a safety standpoint.
Here are some tests you can perform on your own to ensure that you are purchasing high-quality TMT bars.
Bend Test - Bend the bar at 180° and observe the rebar's behaviour.
The end result should be that it does not crack or rupture.
Rebend Test - Bend the bar at 135° and observe the rebar's behaviour.
Please soak it in hot water at 100°C for 30 minutes.
Then bend at 157.5° and observe the rebar's behaviour.
As a result, the bar must bend without cracking.
Examine the mass per metre run: It includes a minimum of four 1-meter samples and weighing them following IS 1786 to determine the nominal mass tolerance.
