A conveyor roller tube (1) including a plurality of co-extruded polymer layers (2, 3). The tube (1) includes an inner layer (2) and an outer layer (3), and an optional intermediate layer. The inner layer (2) is formed of a first polymer material. The outer layer (3) is formed of a second polymer material, The outer layer (3) is formed to have high wear properties, and is also formed to be of a different colour to the adjacent layer (2) thereto so that a visual indication of the wear of the roller tube (1) is provided. 20 26 10 00 00 1 6 Ja n 20 26 ABSTRACT 2026 2026100000 16 Jan
