Outdoor furniture lives a hard life. UV radiation, rain, snow, dust, pollen, bird droppings, and 50 degree daily temperature swings all attack the material continuously. A bad material choice means a sagging, peeling, rusting eyesore within three years and a full replacement at year five. A good material choice means furniture that still looks intentional after 15 years with minimal maintenance. The three dominant materials in 2026 are teak, powder-coated aluminum, and resin wicker over an aluminum or steel frame. Each suits different budgets, climates, and aesthetic preferences. Here is the engineering breakdown.
How teak performs outdoors
Teak (Tectona grandis) is a tropical hardwood native to South and Southeast Asia. The wood contains natural oils (tectoquinones) and a high silica content that together resist rot, insect damage, and fungal attack. Teak is the only common furniture wood designed by nature for outdoor use without any chemical treatment.
The wood weathers in two stages. In year one, the surface fades from honey-gold to a uniform medium gray. In year two and beyond, it deepens to a silver-gray patina that looks like driftwood. This weathering is purely cosmetic. The underlying wood structure remains intact for 25 to 40 years.
Quality grades matter. Grade A teak (heartwood from mature plantations or sustainable harvests) has the highest oil content and longest lifespan. Grade B and C teak are sapwood or younger plantation wood with less oil and a shorter outdoor lifespan (10 to 20 years). Look for FSC certification and a grade designation on the product page. Reputable brands include Westminster Teak, Country Casual Teak, Smith and Hawken (vintage), and Indonesian plantation brands like Kingsley-Bate.
Cost is the catch. A single teak dining chair runs 400 to 900 dollars. A six-seater dining set with table runs 4000 to 12000 dollars. The break-even versus cheaper materials happens at year 10 to 15, after which teak is the cheapest material per year of service.
How aluminum performs outdoors
Aluminum is the most popular patio material by volume in 2026 because it combines reasonable durability with low weight and low cost. There are two main forms: cast aluminum (molded into shapes with decorative detail) and extruded or tubular aluminum (drawn into hollow tubes and welded or bolted into frames).
Aluminum does not rust because there is no iron in it. Surface oxidation forms a thin protective layer that prevents further corrosion. The catch is the powder coat. Bare aluminum is unattractive (chalky and dull), so manufacturers coat it with a baked-on polyester powder coat. This coat is what fails over time, not the underlying metal.
Quality powder coats use a multi-step process: degrease, etch, prime, top coat, and bake at 200 degrees C. Cheap powder coats skip the etch and prime steps, which means the coat adheres weakly and chips off within 2 to 3 years. Look for warranties of 5 years or more on the powder coat finish, which signals a multi-step process.
Frames are typically 1 to 2 mm wall thickness for cast and 1.5 to 3 mm for tubular. Heavier gauges (3 mm plus) feel more solid and are less likely to bend. Weight per dining chair runs 4 to 8 kg.
Sling fabric and cushions are the weak points. The aluminum frame outlasts the fabric by 2 to 1. Plan to replace cushions or rewebbing once during the furniture’s life.
How resin wicker performs outdoors
Resin wicker (also called all-weather wicker, synthetic rattan, or HDPE wicker) replaces traditional natural rattan with extruded plastic strands wrapped around an aluminum or steel frame. The visual effect mimics natural wicker. The durability is dramatically better.
Two resin types dominate. HDPE (high-density polyethylene) is the premium choice. It contains UV stabilizers, holds its color for 5 to 8 years, and stays flexible through temperature swings from minus 30 to plus 60 degrees C. Brands sourcing HDPE include Ecolene (Italian) and Viro (German). PVC resin is the cheap alternative. It fades and cracks within 2 to 3 years. Big-box patio sets under 800 dollars usually use PVC.
The frame is typically powder-coated aluminum (lightweight, rustproof) or powder-coated steel (heavier, can rust if powder coat chips). Aluminum frames are preferred for coastal and humid climates.
Cushions are part of the value proposition. Quality resin sets include outdoor-rated fabric cushions (Sunbrella or equivalent) with quick-dry foam. Lower-end sets ship with polyester cushions that mildew and fade quickly.
Expected lifespan for HDPE resin over aluminum frame: 8 to 12 years. For PVC resin: 3 to 5 years. Cost per dining chair: 200 to 500 dollars for HDPE quality, 80 to 200 dollars for PVC.
Weight, storage, and wind
Teak weighs 700 to 900 kg per cubic meter. A teak dining chair is 8 to 14 kg. Heavy enough to stay put in moderate wind, light enough that one person can move it.
Aluminum is the lightest of the three. A typical aluminum dining chair is 4 to 7 kg. Easy to move, but wind is a concern. In areas with frequent 50 km/h plus winds, aluminum chairs and umbrellas blow over and tumble. Many manufacturers offer sand-fillable bases or weighted feet.
Resin wicker over an aluminum frame is similar to aluminum alone, 5 to 9 kg per chair. Resin wicker over a steel frame jumps to 10 to 15 kg. The steel frame is preferred where wind matters.
For winter storage, aluminum and resin both nest or stack compactly. Teak does not stack as efficiently because of the rigid shape, but it does not need storage. It stays outdoors year round.
Maintenance schedules
Teak: optional. The minimum maintenance is rinsing once or twice a year. Owners who prefer the original gold color apply teak oil or teak sealer annually. Owners who prefer the silver patina do nothing. Annual cost: 0 to 30 dollars.
Aluminum: clean twice a year with mild soap. Touch up powder coat chips with matching paint every 3 to 5 years to prevent corrosion at the chip site. Replace cushions or slings every 5 to 8 years. Annual cost: 20 to 60 dollars amortized.
Resin wicker: clean twice a year with a soft brush and mild soap. Avoid pressure washers (the high-pressure spray frays the resin strands). Replace cushions every 4 to 7 years. Annual cost: 25 to 70 dollars amortized.
Climate fit
Hot dry climates (Arizona, New Mexico, inland California): all three materials work. Aluminum can get hot to the touch in direct sun (test before buying dark colors). Teak handles intense UV without issue.
Hot humid climates (Florida, Gulf Coast, Hawaii): teak and aluminum dominate. Resin wicker holds up but cushions mildew faster. Salt air corrodes cheap aluminum at welds, so specify marine-grade powder coat near saltwater.
Cold snowy climates (New England, Midwest, mountain west): teak handles freeze thaw cycles without issue. Aluminum is fine but cushions and slings must come inside. Resin wicker tolerates freeze thaw on HDPE, but PVC cracks below minus 10 degrees C.
Temperate climates (Pacific Northwest, mid-Atlantic): all three work well. Pick on aesthetic and budget.
Combined recommendation
For a 15 plus year horizon with year round outdoor exposure, teak is the lowest cost per year despite the highest upfront cost.
For a 5 to 10 year horizon with seasonal storage of cushions, powder-coated cast aluminum gives the best balance of price, weight, and aesthetic flexibility.
For a 3 to 6 year horizon on a tight budget, HDPE resin wicker over aluminum frame is the value pick. Verify the resin grade.
Skip PVC resin sets entirely. The 200 dollar savings versus HDPE evaporates when you replace the set in year 3.

Frequently asked questions
Is teak really worth three times the price of aluminum?+
If you plan to keep the furniture for 15 years or more and leave it outside year round, yes. A quality teak set holds up for 25 to 40 years with no structural failure. An aluminum set holds up for 10 to 15 years before fabric slings, welds, or powder coat start to fail. The cost per year is similar, but the teak still looks intentional in year 20 while aluminum looks tired.
Does resin wicker fade in the sun?+
All resin wicker fades with UV exposure. The premium grades (HDPE resin from Ecolene, Viro, or Rehau) hold their color for 5 to 8 years before noticeable fading. Cheaper PVC resin fades visibly within 2 years. Check the manufacturer warranty. A 5 year fade warranty signals HDPE construction. A 1 year warranty signals PVC.
Can I leave teak furniture outside in winter?+
Yes, teak is the only common patio material designed for year round outdoor use without covering. The wood weathers from honey-gold to a silver-gray patina, which is purely cosmetic. The natural oils prevent rot, splitting, and insect damage. Some owners apply teak oil annually to keep the gold color, but that is optional and the wood does not need it for durability.
Which material is best for coastal or saltwater locations?+
Marine-grade powder-coated aluminum or 316 stainless steel. Cast aluminum patio furniture with marine-grade powder coat holds up well within 100 meters of saltwater. Teak handles salt air with no issue. Avoid wrought iron at the coast (rusts within 3 years even with paint) and avoid cheap aluminum with thin powder coat (corrodes at welds and seams).
What about wrought iron or steel furniture?+
Wrought iron is heavy, durable when painted, and traditional looking. The downsides are weight (a single chair can be 15 kg), rust risk if the paint chips, and pinch points from the metal scrollwork. Steel is similar but typically cheaper and more prone to rust. Both are fine for covered patios or dry climates. Skip them for humid coastal or seasonal-snow locations.
