As manufacturing materials is more, the steel pipe is one of the most rare, but the type of steel pipe and can be divided into several different types, so choose, this is also need to be aware of. If frame scaffolding with steel tube is better?

Many are asking this question, the quality of steel pipe directly affected the quality of the scaffold, so must choose good, let's together to get to know the related introduction. Good quality frame scaffolding steel tube, its rich metallic surface, the color of the pink and similar iron will not exist. If it is of poor quality of steel pipe are likely to appear this kind of phenomenon, one reason is the production base material is blank or adobe material; Because of rolling temperature and inferior materials not standard, the steel temperature is through the visual, it is not in accordance with the relevant provisions of austenite rolling area.

So, frame scaffolding steel tube steel performance is not up to standard. Good quality frame scaffolding steel tube, its composition is uniform, and the cold shearing machine high tonnage, neat cutting head face smooth. The poor quality of frame scaffolding steel tube, the cutting head end face tend to be flawed, and see with the naked eye will be uneven phenomenon, there is no metallic luster and the surface. What

Is frame scaffolding steel pipe better? Poor quality frame scaffolding steel tube, the cross section is oval, because producers in order to save the cost of materials, make the finished product quantity of the two way in front of the roller is large, it will make the rebar strength slash, affect the quality of steel pipe. Good, poor quality of steel tube and steel tube will vary a lot, so we must especially pay attention to.
