What’s No Good About Wood

With aluminum, you don’t have to worry about the concerns that plague wood railings:

  • ($) Regularly staining the railing (which releases harmful chemicals called VOCs into the atmosphere).
  • ($$) Replacing part or all of the system once mold and mildew have had a chance to invade the structure and chow down.
