0.71mm galvanized steel wire is a type of wire made from steel that has been coated with a layer of zinc to protect it from corrosion. The coating is applied through a process called galvanization, in which the steel is immersed in a bath of molten zinc. The thickness of the coating is measured in micrometres (µm), and 0.71mm is equivalent to 710 micrometres. The wire is typically used in construction, fencing and other applications where corrosion resistance is important. It is stronger and thicker than 0.36mm wire. It can be used for applications that require more strength like heavy duty construction or industrial use.

FAQs About This Wire

Galvanized Steel Wire Uses?

Galvanized steel wire is coated with a layer of zinc, which protects the steel from rust and corrosion. However, if the galvanized coating is damaged or worn away, the steel underneath may begin to rust.

0.71mm galvanized steel wire has several uses, including:

  1. Construction: The wire is used in the construction industry as reinforcement for concrete structures, such as bridges and buildings.
  2. Fencing: The wire is used to create sturdy and durable fences for homes, farms, and industrial sites.
  3. Cable Armoring: The wire is used as armor for electrical cables and communication cables to protect them from mechanical damage.
  4. Guy wires: The wire is used to support telephone poles and other tall structures by providing tension to hold them upright.
  5. Industrial uses: The wire is used in various industrial applications, such as the manufacture of wire mesh, wire baskets, and other wire products.
  6. Gardening: The wire is used for making trellis for plants, wire cages for animal and bird feeders, etc.
  7. Arts and craft: The wire is used for making jewelry and other decorative items.
  8. Agriculture: The wire is used for making nets, fences and other support structures in agriculture.

These are some of the common uses of 0.71mm galvanized steel wire, but it has many other potential uses depending on the needs of the specific application.

Can Galvanized Steel Wire Be Painted Or Colored?

The galvanized steel wire can be painted or colored, but it requires special preparations to ensure that the paint adheres well. Zinc coatings, while excellent for corrosion resistance, can pose difficulties when painting directly over them. Cleaning the wire with mild detergent or degreaser will remove debris and grease.

Sand the surface lightly with fine-grit sandpaper to create a texture that will allow the paint to adhere, being careful not to remove the protective zinc layer. Primer designed for galvanized metal is essential for improved paint adhesion and a uniform finish.

After the primer has dried, you can apply your chosen paint, preferably an acrylic latex or one designed for metal surfaces.

Give the paint plenty of time to dry and cure according to the manufacturer’s instructions. In spite of the fact that painting enhances the wire’s aesthetics, it might require ongoing maintenance, especially if the wire is exposed to harsh environments.
