Steel pergolas

Two different products are sold as a steel pergola. The all-steel kit, from Backyard Discovery or Sunjoy, is a canopy or open-slat frame at the cheap end, with one louvered range from Backyard Discovery in the middle (Purple Leaf vs Backyard Discovery compares it with another entry-price louvered kit). The steel-post kit, from Mirador or Erommy, puts aluminum louvers on galvanized posts and is a louvered pergola with a lower price and heavier legs. Buy Backyard Discovery if you want all-steel with a warranty. Buy Mirador if you want a louvered roof and do not mind the mix.
