      What is powder-coating?

      Powder-coating a dry finishing process using pigment and resin particles that melt into a durable finish. Ours is eco-friendly and super tough.

      How do I maintain my aluminum railing?

      We recommend checking and cleaning your aluminum railing once a year in normal environments. In more hazardous environments or if heavy soiling occurs, more regular cleaning may be required. To clean, wash the railing with a solution of warm water and mild detergent and rinse to remove all residues. The railing should be cleaned using a soft cloth or sponge. Test the cleaner in a small, inconspicuous area prior to applying it to the entire railing system to ensure that no color change or damage will occur.

      Do Deckorators railings meet building code requirements?

      Deckorators Composite Railing, manufactured by UFP Ventures II, Inc., has been evaluated by an independent third-party evaluation report writer known as Intertek to be code-compliant under Intertek’s CCRR-0171 and CCRR-0335 Evaluation Reports. See reports for complete details.

      How do varying weather conditions affect Deckorators railing during installation?

      Deckorators performs well in varying weather conditions. During installation, it will contract only slightly in cold weather. It expands in hot weather. We recommend that the material be on the job site 48 hours prior to installation to acclimate. Reference the Railing tab on the Installation Instructions page for spacing guidelines to ensure proper room for expansion and contraction.
