The frame is 16-gauge American steel with North Star's extremely durable, rust-free, scratch-resistant, powder coating finish. The table top and shelf are made from 3/4" medium-density fiberboard (no formaldehyde) with a high-pressure melamine overlay.
24" x 24" end wing extensions are available with a plain, smooth finish or with a cut-out to hold a five gallon bucket (for mixing glazes). The extensions can be folded up against the legs when not in use. Max load on extensions is 100 pounds.
