Aluminum vs. Steel vs. Rattan Patio Furniture
Aluminum shows up as a full frame material on the lighter, rust-focused pieces; steel or iron is the more common frame under a woven PE rattan or wicker surface; solid acacia wood appears only on dining products, never as a frame material for seating.
Aluminum
Used as the full frame on the 2-piece armchair set, the 4-piece set with the built-in fire pit table, the 7-piece round-table dining set, both pergolas (aluminum frame with an iron canopy) and the 54 in propane fire pit table. Wisteria Lane's own feature text markets aluminum around rust resistance and lighter weight compared with steel - none of these listings claims aluminum is stronger, only that it won't rust the way untreated steel can.
Steel and iron
The more common frame material under a woven surface: the two 5-piece sectional sets (an all-iron frame), the 7-piece sectional set and the rattan-topped dining sets (powder-coated steel under PE rattan or wicker), the rocking egg chair (iron frame with PE wicker), and the carport (galvanized steel, described by the manufacturer as compressed for bend resistance). Steel and iron carry the weight in this range; rattan and wicker are usually the visible surface over one of the two, not a structural material on their own.
PE rattan and wicker
A woven synthetic surface, not a frame material - every rattan or wicker product in this range sits over a steel or aluminum frame underneath. It shows up on 5 of the 8 conversation-set products and 1 of the 4 dining-set products. Wisteria Lane's own feature text describes it as weather- and UV-resistant; no listing in this catalogue claims it as load-bearing on its own.
Solid acacia wood
Confined to the dining group in this range - the standalone dining chairs, the 5-piece rattan set's tabletop and armrests, and the 9-piece set's table and chairs are all solid acacia. No conversation-set or structure product in this catalogue uses wood as a structural material.
What this doesn't tell you
None of this substitutes for the specific weight-capacity and maintenance figures on each product's own specifications table - a material tells you the general category, not the published number for the piece in front of you.
Questions
Is aluminum or steel stronger?
Neither Wisteria Lane listing in this range makes that claim either way - aluminum is marketed here around rust resistance and lighter weight, steel around load capacity once powder-coated. Check each product's own stated weight capacity rather than assuming from the frame material.
Is rattan or wicker a frame material on its own?
Not in this catalogue - every rattan or wicker product here sits over a steel or aluminum frame. The woven surface is the visible finish, not the structural material.
Which products use solid wood?
Three dining products: the standalone acacia dining chairs, the 5-piece rattan set (acacia tabletop and armrests only), and the 9-piece acacia set (table and chairs both). No conversation-set or structure product in this range uses wood.
