Black Annealed Catchweight Coils

The difference between common wire and BWG™ for hot-dip galvanizing

BWG™ iron wire effectively meets the needs of hot-dip galvanizing plants:

• Zinc savings: its structural and mechanical properties reduce zinc uptake compared to standard wire available on the market
• Safety: high tensile strength is a fundamental mechanical property to prevent breakage risks
• Malleability: with the same strength, it is highly malleable, making tying operations easier for the operator
• Productivity: easier tying and greater safety are the foundation for increased galvanizing plant productivity

25 kg or 50 kg coils with variable diameters

Coils are available in standard 25 kg and 50 kg weights, with diameters ranging from 0,90 mm a 6,00 mm to meet the different needs of plants. Each coil is designed to ensure compactness and uniformity, facilitating storage and daily handling.

The only iron wire for galvanizing plants developed through scientific research

BWG™ – Bottaro Wire Galvanizing – is the result of close collaboration with the most renowned Italian universities, designed to ensure optimal performance in the hot-dip galvanizing process. Thanks to advanced studies, it is the benchmark wire for efficiency, strength and reduced zinc uptake.

Use fewer wires and reduce zinc adhesion during the process

BWG™Plus wire is the technological answer for hot-dip galvanizing plants focused on efficiency and sustainability. Its thicker diameter (up to 5 mm) makes it possible to reduce the number of wires required for each tie — and therefore the surface area of the knot where zinc is deposited — allowing for significant raw material savings.
At the same time, thanks to its softness and malleability, it ensures ease of use and operational continuity without compromise.
