First, look at the uniformity. According to the customers steel frame manufacturer, the average quality steel frame has fewer defects and most of it has no pitting. After the factory test, it was found that the so-called marijuana surface phenomenon is caused by the wear of the grooves, which may cause surface irregularities. Although it does not affect the use, it will reduce the appearance from the quality. In particular, wholesalers who have stricter regulations on steel frame profiles should pay attention to the choice. In addition, the uniformity of the steel frame means that the steel frame has less impurities and a uniform color. Some equipment manufacturers have perfected the production of advanced steel frame plants. The steel frame has few impurities and no crusts. Secondly, looking at the color and whether there is crack, the important feature of the high-quality steel frame is that the transverse rib is thicker and higher, but in general, if the steel frame is clear red, it means that the steel frame is of good quality and is only suitable for ordinary products. Production. If the steel frame is similar in color to the pig iron, the quality of the product is average.
