Permacoat Easier Installation Fence contractors prefer the PermaCoat chain link fence framework over traditional heavy mil coatings. The PermaCoat coating has a smooth finish making the material easier to install through loop-caps and/or barb-arms. This easy installation helps save time on projects by not tying up valuable resources on a simple install. The PermaCoat chain link fence framework is also the preferred choice for fabricating gates and other structures such as chain link fence backstops and tennis courts.
