      Are Deckorators aluminum railings still building code approved if a post extension is added?

      Yes, the use of post extensions does not affect the compliance with building code as long as they are used according to our instructions. Please note that post extensions are not intended for use with shade sails or similar applications. For detailed installation guidelines, refer to our installation instructions page.

      How do I maintain my aluminum railing?

      We recommend inspecting and cleaning your aluminum railing once a year in normal environments. In more hazardous environments or if heavy soiling occurs, more frequent cleaning may be required. To clean, wash the railing with a solution of warm water and mild detergent, then rinse thoroughly to remove all residues. Use a soft cloth or sponge for cleaning. Before applying the cleaner to the entire railing system, test it in a small, inconspicuous area to ensure no color change or damage occurs.

      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 various weather conditions. During installation, it contracts slightly in cold weather and expands in hot weather. We recommend keeping the material on-site for at least 48 hours before installation to allow it to acclimate. Refer to the Railing tab on the Installation Instructions page for spacing guidelines to ensure proper expansion and contraction.

      Deckorators Aluminum Railing offers great looks and long-lasting performance—backed by a lifetime limited warranty on manufacturing defects and a 10-year salt water applications limited warranty.
