Made with steel, Fortress Building Products’ pergolas benefit from the material’s modern aesthetic, low maintenance, weatherability, and resistance to fire, corrosion, twisting, insects, and rot. The pergolas can be configured in numerous custom setups—without specialized tools—in three style options, and then finished with composite boards. Pergolas include a 25-year limited warranty; pricing for one that measures 10 feet by 12 feet starts at $1,500. fortressbp.com
