construction twisted soft black annealed iron wire

PRODUCTION DESCRIPTION

Black annealed iron wire, also known as binding wire, fire-fired wire, has good flexibility and is widely used. It is made of high-quality iron wire, and is refined by the national standard low-carbon steel wire rod through pickling and derusting, drawing and high-temperature annealing.

BLACK ANNEALED IRON WIRE

Black annealed wire has good elasticity and flexibility, and its softness and hardness can be controlled during the annealing process. It is made of high-quality iron wire and is mainly used as binding wire and binding wire in the construction industry. The wire numbers mainly include 5#-38# (silk warp 0.17-4.5mm), which are softer and more flexible than ordinary black iron wire, with uniform softness and uniform color. Or we could also customize the wire diameter according to customer’s requirement.
Due to its strong flexibility and good plasticity, black iron wire is widely used in various fields such as construction industry, handicrafts, woven wire mesh, product packaging and daily civilian use. Among them, the 1.6mm wire has been machined and spooled. It is mainly used for mowing machines and is extremely popular in the Saudi market.
