In the form of scaffolding tube frame according to the weld seam welded scaffolding tube and spiral welded scaffolding tube. Straight seam welded scaffolding tube production technology is simple, high production efficiency, low interest rates, rapid development.

The strength of the spiral welded scaffolding tube is generally higher than straight seam welded scaffolding tube, use a narrow billet production of larger diameter welded scaffolding tube, you can also use the same width of billet in the production of different scaffolding tube diameter welded scaffolding tube. But compared with the same length of straight seam scaffolding tube, weld length increase 30-100% and production rate is low.

As a result, a small diameter welded scaffolding tube are mostly with straight seam welding, large diameter welded scaffolding tube for the most part adopts spiral welded.
 
Shelf tube than straight seam steel scaffolding tube of low cost, high production efficiency. Straight seam steel scaffolding tube production process is simple. Interest is low, rapid development.

The strength of the spiral welded scaffolding tube is generally higher than straight seam welded scaffolding tube, use a narrow billet production of larger diameter welded scaffolding tube, you can also use the same width of billet in the production of different scaffolding tube diameter welded scaffolding tube. But compared with the same length of straight seam scaffolding tube, weld length increase 30-100% and production rate is low. As a result, a small diameter welded scaffolding tube are mostly with straight seam welding, large diameter welded scaffolding tube for the most part adopts spiral welded.
 

Because of the different welding process is divided into furnace welded scaffolding tube, welded (erw) tube and automatic arc welding tube. Because of its divided into straight seam welding form two kinds of steel scaffolding tube and spiral welded scaffolding tube. Because of its shape is divided into circular welded scaffolding tube and alien (square, flat, etc) welded scaffolding tube. Welded scaffolding tube because of its material and use different and divided into the following several varieties: tube billet is steel plate or strip steel shelf.
