Most people are relatively unfamiliar with I-beams, especially I-beams and H-beams, which many people will confuse. In fact, the production process and method of these two kinds of steel are very different, so what are the differences between I-beam and H-beam? Let's take a look.
How to see if it is inferior I-beam
1. Fake and shoddy I-beams are easy to fold
If it is an inferior I-beam, it can be easily bent, making the I-beam lose its original shape. The main reason for this is that the manufacturer blindly pursues high efficiency and the amount of pressure is too large, resulting in a decrease in product strength and easy to be bent.
2. The appearance of fake and shoddy I-beams often has a hemp surface
The surface of inferior I-beam often has a matte surface, mainly because of the uneven surface caused by the wear of the rolling groove, so it is necessary to carefully see whether there is such a defect on the surface when purchasing.
3. The surface of fake and inferior I-beams is prone to scarring
Usually, poor quality I-beams are prone to impurities and scarring on the surface, so it is easy to distinguish the quality of I-beams from this point.
4. Fake and inferior I-beams are easy to scratch
The production equipment of many manufacturers is relatively simple, and the production technology is not up to par, so the surface of the I-beam produced will produce burrs, and the strength of the I-beam is not up to standard.
5. Fake and inferior I-beams have no metallic luster
In general, low-quality I-beams have a reddish color and are not as shiny as metal. The main reason is that its blank is adobe, and the temperature is not standard during production, so the produced I-beam is matte.
