Product details

Talking about the grade that is S235JR is a non-alloy structural steel that is widely used for manufacturing steel products. Due to its high tensile strength and other mechanical properties this it is considered as one of the best grades of industries used for manufacturing. These square tubes are known best for their high tensile strength, durability, workability, long functional life, formability, dimensional accuracy, and ductility. They are even designed in such a way that it can easily fulfill the needs of a variety of applications.

Testing and packaging

To know the quality and performance of these tubes, numerous inspections and tests are performed. All these tests and inspections are done at different temperatures and environment. The tests include flaring test, third-party inspection, visual inspection, macro, and micro test, flattening test, radiography test. There are some more tests done like a destructive test, non-destructive test, chemical composition analysis and more.

The entire testing process takes place under the strict supervision of experts for which test certificates are approved. At last, S235JR Square Tube is packed in bundles that helps prevent rust and other uncertain damages.
