Why BWG Plus?


  • ABSORPTION Less wires means lower zinc absorption
  • SAFETY: Wider knots and higher tensile strength
  • MALLEABILITY: Easy to tie even at high thicknesses
  • SAVING: Less wires to tie means less working time to be spend

WRITTEN BY: prof. R. Fratesi

[…] Unfortunately the zinc remains adhered on the wires and is not generally recovered, but consumed. Hence the need to use steel wires that limit the amount of zinc adhered on the wires themselves. The zinc lost equals the sum of what remains adhered metallurgically by reaction with the steel and of that remaining trapped in the nodes and in the interstices between the wires that make up the strand.  […]

Matter of saving

BWG Plus™ is the only special iron wire perfect for the companies with high wire consumption. The diameter of the wire is bigger than the one that is normally used. The knot will have the wider angle that will increase the tensile strength and therefore the safety for the departments.

The perfect choice for protection of healthcare workers

The packages are studied in order to respect all the international laws regarding the health and the material handling of each single worker. Customer’s technical offices choose BWG wire for its malleability, since it “reduces the effort and the possible risk of wrist and tendon inflammations”.

Who reccomends BWG

BWG is the top brand in the hot-dip galvanizing industry. Two sector’s leader recommend Bottaro’s wire to get the best performance.
