Wood or Aluminum - Which Is Better?
November 12th, 2008Years ago, outdoor furniture meant a chair or glider on a porch. Wood was the material of choice because it was plentiful, inexpensive, and could stand up to the sheltered location where it was used. While porches are still around, the deck or patio has become more common. That means furniture for those locations has to endure blazing sun and inclement weather, such as snow, rain, and ice.
Sure, furniture covers are available for aluminum or wood furniture, but even under a cover wood shrinks and expands, loosening joints that need periodical re-tightening which can lead to eventual erosion of bolt holes. Today, aluminum outdoor furniture is the most practical choice. At a slightly higher cost, you typically get a baked on finish that will not fade in the sun like paint on wood does. Aluminum furniture is usually cast and not subject to the same styling limitations as wood. Artistic and imaginative shapes can be created at lower cost than would be necessary to carve wood. Joints are at a minimum and since aluminum does not shrink or expand like wood, joints that are part of the furniture do not have to be retightened very often.
Wood outdoor furniture is usually heavy enough that rearranging for different purposes, such as a party, can be a chore. Aluminum chairs, tables, and lounges are very lightweight allowing easy rearrangement for different occasions. Some chairs and tables fold and can be carried easily by even a child. All outdoor furniture needs occasional cleaning.
While you can simply hose off either wood or metal furniture, water on wood is not a good idea unless the wood is water resistant like more expensive cedar or redwood. When water gets in the joints, it is hard to get out which can be a problem for cheaper woods that tend to rot. Plus, wood absorbs water which causes it to expand and increasing pressure on joints. If the joint eventually dries out, the wood contracts. This contraction – expansion process causes joints to weaken over time. Cast aluminum furniture has no joints so water is not a problem. Aluminum furniture with joints does not absorb water.
Joints – if there are any – remain as solid as the day the furniture was made. Remove the cushions, get out the hose, and spray away. Aluminum has the added advantage that, unlike wood, the occasional spilled drink or grease from a hamburger will not affect it. Last, but certainly not least, aluminum patio furniture can be painted to match your changing décor tastes, a whole lot more easily than wood.
