Most are built from solid teak wood for frames and surfaces. Some designs combine teak with metal framing (for example, stainless steel) for added strength and a mixed-material look.
Listings mention galvanized steel hardware to help prevent rust, and at least one product pairs teak with #304 stainless steel framing for improved corrosion resistance.
Routine care is simple: spot-clean or wipe down to remove soap and dirt. Some listings recommend occasionally treating teak with teak oil or a water-based finish to preserve appearance, but regular wiping is usually sufficient for everyday upkeep.
