expanded metal mesh material

Stainless steel blade barbed rope material is produced according to stainless steel plate and stainless steel wire, as a whole have achieved the purpose of high quality anticorrosion.

The above are the three major advantages of the positive and negative twisting barbed wire, mainly including durability, high cost performance, and beautiful appearance.

The drawing process of the product drawing process has a great influence on the product function. Generally, a large total surface reduction rate of about 90% (see area reduction rate) and a small pass surface reduction rate (about less than 23%) are selected to ensure the endurance of the product. On the high strength spring steel wire, drawing should control the exit temperature of each passage of the steel wire is lower than 150℃, to avoid the steel wire due to strain aging and appear to change the crack, which is the formation of steel wire scrap the primary disadvantage.

Non-proportional extension strength: It is mainly for hard steel without yield point. It is defined as the stress where the residual elongation of the standard distance part reaches 0.2% of the length of the original standard distance.
