Galvanized Wire Mesh

Galvanized Wire Mesh

Galvanized wire mesh is a wire product made of interlocking metal that is coated with zinc. It is very corrosion and rust resistant, and is therefore used in many outdoor applications within the commercial and industrial spheres to serve the construction, engineering and agricultural industries. Galvanized wire mesh is used to manufacture many different products, including fencing, fish traps, screen door guards, tree guards and animal cages. It is also used in building construction as reinforcement to bricks and concrete. The mesh is made of ferrous iron or steel alloys with oxidation states of +2 or +3. Galvanized metals are protected from harmful atmospheric elements for 15 to 20 years, even if the coating is damaged.

During the manufacturing process, iron or steel wire is welded together vertically and horizontally and then put through post-forming processes to increase its properties. Galvanizing metal mesh can be accomplished 2 ways-hot dipping and an electrolytic process. During hot dipping, the mesh is dipped into molten zinc which has been heated to 860 degrees F. The zinc reacts with the steel or iron to form a brittle zinc-iron alloy, which has a wide-range temperature resistance. The electrolytic process is a post-forming cold process where the mesh is painted with organic solvent containing zinc particles. When the solvent evaporates, the zinc remains and reacts with the iron or steel.
