Bead wire

Bead wire is dry drawn high carbon wire with bronze coating. We produce normal tensile bead wire (NT) and high tensile bead wire (HT). Diameter range is from 0,89 mm up to 2,5 mm.

Example of our bead wire parameters

*testing length of sample with diameter <1,0 mm => L = 200xd; with diameter >1,0 mm => L = 100xd

Bead wire parameters can be adjusted based on customer needs.

Packaging – returnable spools

Bead wire is standardly delivered on spool BS900 or BS1150 in metallic racks.

Spool dimensions are in following table.

		BS 900	BS 1150
K – Spool diameter	mm	760	760
L – Core diameter	mm	355	355
M – Spool width	mm	330	370
N – Winding width	mm	280	320
O – Core hole diameter	mm	35	70,5
P – Number/diameter of drive holes	mm	2/35 + 2/20,5	2/35 + 2/20,5
Q – distance of drive hole from the middle	mm	115 + 63,5	115 + 63,5

Wire on spool is protected by PE foil or anticorrosive paper or combination of both. All deliveries have certificate of analysis. We can also send test samples if required. Samples are packed in PE foil bag with humidity indicator and desiccant. We can also supply bead wire on Z2 coils. For more information please contact our commercial director.
