Product Details

construction BWG12 bright black iron annealed soft wire

We produce the annealed wire with high-quality low carbon raw materials through wire drawing, anneal process. Its soft and has good stretching resistance. The finished products are smeared with slushing oil. So they are not apt to rust. We can tie up the products according to customers requirements, ranged from1 to 50 kg each bundle.

Soft annealed wire, also known as annealed wire, offers excellent flexibility and softness through the process of oxygen free annealing. Soft annealed wire is mostly used in woven wire mesh or as wire tie.

Iron wire can be processed into cut wire or U type wire for binding uses.

We offer two kinds of annealed wire, bright annealed and black annealed wire.

Black annealed wire gets its name from its plain black color.

Wire Materials: Carbon steel wire.

Uses: Black annealed wire is mainly processed into coil wire, spool wire or big package wire.

Or further straightened and cut into cut wire and U type wire.

Annealed wire is used as tie wire or baling wire in building, parks and daily binding.

Packing: Spools, Coils.

Wire Diameters: Similar to galvanized iron wire, from 5mm to 0.15mm (wire gauge 6# to 38#).
