Series 901 cleanroom walls are available in three standard designs, with custom sizes and shapes available to suit various application needs. The standard wall panel is constructed of white vinyl-covered steel. The 18-gauge steel is laminated with textured vinyl on one side and smooth vinyl on the opposite side. The panels are also available with an unpainted stainless steel finish, smooth or textured baked enamel, epoxy, or conductive finishes. The painted panels may be painted to colors other than the standard white.
