What Does Steel Rhs Mean And How Is Rectangular Steel Identified?

There are many types of steel on the market, each using a different designation. So what does steel RHS mean? What is the identification method of rectangular steel? Let's take a look at it.

What is the meaning of steel rhs?

Steel RHS refers to a rectangular hollow type of steel, using hot-rolled or cold-rolled strip steel as the main material, and then use the cold-formed machine for molding. This type of steel not only has very good comprehensive mechanical properties, welding ability is also very strong. At the same time, it also has corrosion resistance and good toughness and other advantages, so it is widely used in the market.

What is the identification method of rectangular steel?

1, shoddy rectangular pipe is prone to folding

In the purchase of rectangular steel, we can identify the authenticity by looking at its surface folding, for shoddy rectangular steel pipe, folding only enough to its surface will appear a variety of folding lines. This is mainly because some businessmen only pursue high efficiency, in the production process under pressure is large, resulting in the ear, and the strength of the steel is followed by a big drop.

2, shoddy rectangular tube appearance often have the phenomenon of hemp surface

Normally shoddy rectangular tube, its surface will carry some pockmarked phenomenon, which is due to the production process of rolling groove wear and tear caused by serious defects. Because the manufacturer is the pursuit of profit, so often appear this rolling groove exceeds the standard.

3, shoddy material surface easy to produce cracks

Generally speaking, the quality of the steel it is easy to crack the surface, because it used billet is adobe, and adobe with a very large number of pores, when it is subjected to thermal stress in the production process, the surface will appear cracks. At the same time, this kind of steel is also very easy to be scratched, because of the problem caused by the poor equipment, the strength is also relatively low.
