• ProCoat Duct Systems

    Linx Industries brings ProCoat products to the market as an alternative to PVC, PDS, PCD, and other precoated steel products.
    The coating exhibits superior chemical resistance characteristics over precoated sheet metal alternatives. In addition,
    ProCoat ductwork can be fabricated using industry standard welding methods, adding quality while maintaining aesthetic appearance and
    corrosion resistance. The coating is white, however, desired RAL colors can be specified and even custom matched.
