There are primarily three types of coatings available; galvanized, spectra and Permafused ll.
Galvanized: The zinc coating applied will protect the underlying iron or steel material to prevent it from rusting. The most common method used is hot-dip galvanizing where the parts are submerged in a bath of molten and hot zinc.
Spectra: This coating will provide the corrosion protection of zinc, with the durability and attractive appearance of a colored polyester framework and extruded PVC fabric. This will ensure that your fence remains attractive for years to come and give it a reliable performance that will blend in beautifully with the surrounding environment.
Permafused ll: This is the new generation in color chain links. It offers top notch performance, featuring a polyolefin coating. It is a great long term coating that is durable, UV resistant and maintenance free.
