Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.

Different from common zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach 6-8 times of the former, so there is a great advantage in the service life, ordinary products begin to corrosion three to five years while the latter will take longer to change. Stainless steel barbed rope is in material protection so durability is also better, these two products are long service life, but in terms of high price.
