All galvanized chain link fences at Walcoom are made from the woven and interlocking steel wire with premium quality. The hot-dipped galvanizing process ensures a fully protective zinc coating on all surfaces of the chain link, even the cut ends. There are two ways for chain link fabric galvanization: Galvanized After Weaving (GAW) and Galvanized Before Weaving (GBW). GAW is more popular as it ensures that all the wires of the fabric are coated, including the cut ends, and GBW eliminates burrs and sharp surfaces and increases the tensile strength of the fence.
The weight of Zinc-coated on chain link fence fabric conforms to ASTM A392, available in two coating weight classes as follows (List of data is the minimum value):
