Quick Detail:
BS31 BS4568 GI Conduit Pipe Pre-galvanized Q195/Q235 Steel Class 3 Threaded Conduits British Standard with Coupling
Material: GI conduit pipes are typically made from steel that has been coated with a layer of zinc through a process known as galvanization. This zinc coating provides corrosion resistance, making the conduit suitable for use in both indoor and outdoor electrical installations.
Sizes: GI conduit pipes come in various sizes,BS4568 ranging from 20mm to 50mm in diameter, BS31 ranging from 3/4"-2". The choice of size depends on the quantity and size of the electrical wires or cables that need to be routed through the conduit.
Threads: BS31 BS4568 GI conduit pipes are threaded at both ends, allowing for easy connection to fittings and accessories. The threading is typically in accordance with standard thread sizes, making it compatible with various conduit fittings.
Installation: GI conduit pipes are typically installed along walls, ceilings, or other structures using appropriate support brackets, clamps, or hangers. The pipes can be bent or cut as needed to route wires to their destination.
Standard:BS 4568, BS 31
Thickness:Thickness we can produce 1.2 - 1.6 mm, can as customer request thickness within the period .
Length:3.75M for BS4568 Conduit ; 3.81 M BS31 Conduit
