24 | 877.560.9545 | STAINLESSCABLERAILING.COM When stainless steel cables and hardware come into contact with exposed aluminum components, the dissimilar metals interact with each other, resulting in galvanic corrosion. The best way to prevent this type of corrosion is through keeping the two metals separate, which is part of the reason we powder-coat all of our aluminum products. We also dip-spin the screws included with our base plates in brush-on electrical tape to prevent corrosion within the post screw chases. To further ensure these metals stay out of contact, we have developed specialized products for our customers. Our screw covers are composed of three pieces that snap together around any post-mounting bolt or lag. They completely envelope each part of the screw that would otherwise come into contact with the aluminum base plate or post. Order 4 covers per base plate or 2 per fascia-mounted post. In addition to the incidental touching-up of any scratches or nicks acquired during installation, our touch-up paint also doubles as a brush-on isolator. After cutting the ends of your aluminum posts or drilling holes, coat the fresh edges with touch-up paint to cover the raw aluminum and seal the protective paint layer. Screw Covers Easy to lose in the field. Order 5% extra. ESTIMATOR TIP Touch-Up Paint Use after cutting or drilling holes into your posts.
