Chain link in Karachi also known as chain mesh or wire netting, is a type of woven fence made of galvanized steel wire. The wire is bent into a zigzag pattern and interlocked with itself to form a diamond-shaped mesh. The ends of the wire are bent over and twisted together to create a continuous fence. Chain link is commonly used as a boundary fence for both residential and commercial properties, and is known for its durability and affordability. It can also be used for a variety of other purposes such as creating enclosures for sports fields, animal cages, and construction sites.
