Residential Chainlink

Galvanized After Weaving (GAW)

GAW Chain link Fence Fabric provides exceptional security and protection in commercial, industrial, institutional, recreational and residential fencing applications. Hot dipped zink galvanizing is a simple process with over 200 years of proven effectiveness in millions of applications worldwide. There are other zink galvanizing processes and other metallic coatings. None surpass GAW in durability and protection.

The Importance of GAW

GAW fabric is the only chain link fabric that’s coated after weaving, ensuring that all surfaces of the base metal are protected. With any pre-coated wire, the weaving process leaves the twist and knuckle tips bare from trimming. Cut ends may be dipped in other materials, but they are no substitute in protection for the thorough zink coating of the GAW process.

The Value of GAW

When specifying chain link fabric, insist on GAW produced in accordance with ASTM A 392. If your looking for durability and rust-prevention, there’s no better chain link fencing than GAW. Fewer long-term maintance problems mean lower long-term cost and greater life-cycle savings. Pound for pound, GAW fabric is by far your best value.

GAW fabric, also referred to as Galvanized After Weaving, provides exceptional security and protection. Produced from wire which is first woven into fabric and then galvanized with a zinc coating, GAW is the only chain link fabric that is coated after weaving, ensuring that all surfaces of the base metal are protected against rust and corrosion. GAW has the demanding requirements of ASTM specification A392, and is available in two classes of coating: Class 1 which has 1.2 ounces of zinc coating per sq. ft., and Class 2 which has 2 ounces of zinc coating per sq. ft. The life of a fabric is directly related to the wire gauge and coating thickness, the thicker the wire and coating, the longer the life.

Fabric Terminology Gauge: Refers to the diameter of the wire used to produce the fabric; the higher the gauge number the smaller the wire diameter. Mesh Size: Is the clear distance between parallel wires forming a diamond; the smaller the mesh size, the tighter the fabric. Selvage: Refers to the way the individual ends of the wire are finished after being woven together. The wire can be “knuckled” to avoid sharp ends or “Twisted” when more security is required. Self Healing of ZINC All zinc coatings have “self healing,” or cathodic properties which protect exposed core metal. Even after years of wear, the remaining zinc stays alive. Zinc is the most electrochemically active of all metals used for protective coatings. Meaning, zinc provides a far superior coating in both barrier and cathodic protection. Zinc Protects Base Steel Even When Scratched: This is what happens at a scratch on galvanized steel. The zinc coating sacrifices itself slowly by galvanic action to protect the base steel. This sacrificial action continues as long as any zinc remains in the immediate area. Framework Having strong framework is important when installing a chain link fence as it is the backbone of the entire structure. Make sure you are choosing the right components to withstand all application conditions. Matching galvanized steel framework is available in a variety of gauge and diameter sizes, for 3’ to 12’ high chain link fence systems.

Gauge – refers to the diameter of the wire used to produce the fabric; the higher the gauge number the smaller the wire diameter.

Mesh Size – is the clear distance between parallel wires forming a diamond; the smaller the mesh size, the tighter the fabric.

Selvage – refers to the way the individual ends of the wire are finished after being woven together. The wire can be “knuckled” to avoid sharp ends or “Twisted” when more security is required.
