Round Steel Conduit
Our galvanised round steel conduit range provides a strong and durable cable management solution where enhanced mechanical protection is required. Available in 20mm and 25mm sizes, the system includes heavy-gauge conduit lengths alongside compatible circular boxes, couplers, bends, inspection fittings, bushes, saddles and other accessories for creating complete conduit runs. Class 4 conduit lengths are hot-dip galvanised inside and out, providing a robust finish while the steel construction also provides an effective path for electrical continuity when correctly assembled. For faster installation, the Demon Cato Conlok range provides quick-fit boxes, couplers and accessories that mechanically lock onto standard steel conduit without requiring the tube to be threaded after cutting. With conventional threaded and quick-fit solutions available, the range gives electrical contractors a versatile choice for demanding commercial and industrial steel conduit installations.
