Iron barbed wire is commonly used for fencing in agricultural and security settings. This type of wire consists of sharp barbs placed at intervals along the strand, which act as a deterrent against unauthorized access or animal escapes. In agriculture, barbed wire is used to contain livestock within designated areas, preventing them from straying and causing damage to crops or property. In security applications, it is used to enhance the perimeter defenses of properties, adding an extra layer of protection. The durability and effectiveness of iron barbed wire make it a popular choice for these purposes.

 Dark annealed wire, also known as black annealed wire, is an annealed wire that is coated with a black oxide layer to provide corrosion resistance. This makes black annealed wire suitable for outdoor applications and ensures a longer service life, even in harsh environments.

 16-gauge dark annealed wire is a lighter option often used for crafting, DIY projects, and light-duty applications.  16-gauge dark annealed wires thinner diameter and malleability make it easy to work with while still providing sufficient strength for its intended use.
