Plasti-steel was a metallic material known in the 23rd century. Soron's Hole, a bar in the Orion Colony on Daros IV, used plasti-steel tables. Though this was an expensive choice, they were too heavy to lift and hurl at someone in a brawl, making it a wise choice of furnishing. (FASA RPG module: Orion Ruse) Plasti-steel may be related to plasteel.
