The average person understanding of steel tube, just stay in the literal does not know more the classification and application of steel tube is made of iron scaffolding tubes. Actually even on this category, welded steel scaffolding tubes will be divided into straight seam welded scaffolding tubes and spiral welded scaffolding tubes.

The practical application of the two scaffolding tubess, there are also different. This is all people in the long-term production practice and developed gradually.
Since be welded steel scaffolding tubes, as the name implies, is through the flat strip bending the scaffolding tubes welded together. And straight seam welded scaffolding tubes is the shape of the weld is a straight line, from one end of the play has been unicom to the other side. The shape of the spiral welded scaffolding tubes welding is a spiral.

It should be noted that the straight seam welded scaffolding tubes can be made into tube, but the spiral weld scaffolding tubes is usually circular tube. This is due to different craft. So when we compare, also only is straight seam welded scaffolding tubes in the difference between scaffolding tubes and spiral welded scaffolding tubes.

To differentiate between the two kinds of welded steel scaffolding tubes is also very simple, as long as the weld shape can separate. More intuitive approach is to look at the size. General welded steel scaffolding tubes specification is bigger, often use spiral welded. And compressive ability and security of the spiral welded scaffolding tubes will be slightly higher.

Of course, all of these means that the welded steel scaffolding tubes prices will also be a rising tide lifts all boats. Or when we choose depends on your needs.
