All construction material should be subject to tests and data analysis as the most crucial part of understanding the basic characteristics of the same material. All materials or substances like metals, ceramics, and plastics have varying conditions. We obtain data that acts as a foundation to specify the suitability of the materials for various applications. Steel bars not being an exception, it should equally be tested before pressing them into numerous specific uses.
In fact, the most common test for steel bar reinforcement is the tensile test, bending test, and chemical analysis. Dytron Steel is one company that continuously does research on these aspects of TMT bars, thereby making them one of the top TMT bar companies in Kolkata.
Mill Certificate
It refers to a quality assurance document that one uses in the metal industry showing a metal product's compliance with the international standards. It has to accompany materials to intermediate suppliers and finished goods manufacturers. It certifies both the chemical and physical properties. This document provides the end-user of the raw material verification that the material they receive is per the order requirements. Also, it helps maintain the traceability of the material from the inception stage to inclusion in a finished part.
Bending Test
A bend test is an inexpensive qualitative test that is used to determine the flexibility and soundness of materials. Bend tests deform a test steel material midway causing a bend to form without a fracture. Consequently, you specify the material's resistance level. A bend test's goal is to load the sample material into a specific shape.
Bend tests help determine whether a material will fail under pressure especially in construction processes. The frequency of bending test is necessary to maintain so that no steel reinforcement with failed bending test reports can be used and prevent it from the possible structural issue.
Tension Test
A tension test of materials is a destructive process that provides information about the tensile strength, yield strength, and elasticity of the sample. This test is done to determine how the material reacts when you apply force on it. Usually, by pulling the metal, you identify the material's tensile strength, yield strength as well as how much it will elongate.
Tension test is one of the critical criteria where you submit a steel bar sample to tension which is under control until the failure stage.

Tension testing is essential:
* Predicting a material performance in use under normal and extreme forces.
* Finding out the requirements' specifications to ensure meeting the regulation of the contract.
* Providing a basis for technical communication.
Yield Strength Test
Yield strength refers to a test to find out the maximum stress of a material that will be used for a certain product. This test is conducted to find the elastic limit of a certain material without causing plastic deformation. This test is really necessary before it is converted to a product that will be used by the public. Thus, a manufacturer will only choose a material that has sufficient yield strength for their products.
