Also referred to as angle irons or angle bars, steel angles are finished steel products made through hot-forming semi-finished carbon steel. As steel angles are mainly used for providing structural support, the most ideal composition is a low alloy, yet high-strength steel with better ductility and toughness. With this in mind, the different uses of steel angles can vary from bridge ways, warehouses, equipment manufacturing, support frames, shelves, or even utility carts.

Although steel angles are considered to be the most basic version of any roll-formed steel, they offer excellent advantages, especially when it comes to framing, reinforcement, aesthetic trims, brackets, and the like. Combined with the inherent properties of low-alloy steel, these angle bars have been a reliable assembly part or construction material, depending on the use.

There are many tests for steel quality test. But for that, we need a lab or equipment.

Here I am going to tell you how you can simply check steel quality during purchasing.

THE NAKED EYE TEST TO CHECK STEEL IN THE SHOP:

1. Its very Simple just pick up a bar and check whether the manufacturers seal is present on every meter of it.
2. The bars should not look rusty.
3. Also, check whether the ends of each bundle of TMT rods are of equal length.
4. Ensure each bar in the bundle has the logo of the TMT bar company, without fail.
5. Finally if possible check their weight per bundle.
