ABS rod and sheet ABS - Engineering Grade Sheets & Rods ABS - Engineering Grade Sheets & Rods ABS has perhaps the best balance of properties when cost is a factor. It has good chemical and stress-resistance as well as a combination of toughness with rigidity and creep resistance. ABS Engineering Grade Sizes & Shapes: ABS Rods up to 6" diameter in standard 8 foot lengths. ABS Sheets / Plates are available in two types: Compression Molded Sheets are available up to 4" thick in 48" x 96" Standard thickness tolerance is +/-10%. PLUS ONLY Compression-Molded Sheets are available upon request at an additional cost. Extruded Sheets are produced up to 24" x 48", and are sold upon special request only. Note: Extruded Sheets have a better thickness tolerance than molded sheets. (also more expensive) Note: Sheets larger than 24" x 48" can be expensive to ship To save on freight, select the smallest sheet you can use
