According to the safety technical specification jgj231-2010 for socket type steel pipe support, the model of coiled scaffold is designed,

They are mainly divided into type A and type B.

Type A: it is commonly known as series 60 in the market. In other words, the diameter of vertical pole is 60mm. It is mainly used for heavy support, such as bridge engineering.

Type B: that is 48 series, the diameter of vertical pole is 48mm, mainly used in housing construction, decoration and other fields.

In addition, according to the connection mode of the vertical pole of the turnbuckle scaffold, it can be divided into two forms: the outer sleeve connection and the inner connecting rod connection.

At present, the internal connection is generally used for the 60 series of coil scaffold in the market, that is, the connecting rod is connected inside the vertical pole.

48 series of coil buckle scaffolds are generally connected by outer sleeve, but also connected by inner connecting rod, especially in the field of stage frame, lighting frame and so on.
