Inspection of steel bars and process inspection of steel bar joints
When inspecting steel bars, the first thing to do is to check the brand number and quality certificate of the steel bars; secondly, to check the appearance, take 5% of the steel bars from each batch, and check that there should be no cracks, wounds or laminations on the surface, and the bumps on the surface of the steel bars should not exceed the horizontal limit.

The wide application of aluminum
Aluminum has a density of 2.7g/cm³ (one-third of the density of iron and copper), good ductility, and conductive capacity of two-thirds of copper wire, but the quality is only one-third, the price is cheaper, and it is widely used in the manufacture of high-voltage wires, cables, and radio industries.
