Steel plate is a very important building material, which plays a very important role in many construction projects. As a building material, what should be paid attention to when choosing steel plate? Z would like to share it with the steelmaker for you!
1, Z to introduce steel manufacturers in the purchase of steel, fake steel will be easy to fold. Folding is a variety of broken lines formed on the surface of steel, in fact, this defect often runs through the entire product longitudinal. The main reason for folding is that shoddy manufacturers pursue high efficiency, and the amount of pressure is too large to produce ears. Then the next rolling will produce folding, and the folded product will crack after bending, and the strength of the steel will decrease greatly.
2. When purchasing steel, there will be pockmarks on the appearance of fake and inferior steel. It is due to serious wear groove caused by irregular uneven steel surface defects. There is also the pursuit of profits due to shoddy steel manufacturers, so there will often be groove rolling exceeded the standard.
3. When purchasing steel, the surface of fake and inferior steel will be very easy to scar. There are two reasons for this: the quality of fake and inferior steel is uneven, among which many impurities; Shoddy and inferior material manufacturers guide equipment is simple, easy to stick steel, these impurities bite roll after easy to produce scarring.
4, Z to the steel mill home in the purchase of time, fake and inferior material surface is easy to crack, the main reason is that it is the blank is adobe, adobe pores, adobe in the process of cooling due to the effect of thermal stress, so crack, after rolling, crack.
