Our GI conduit, also called galvanized electrical conduit, is zinc-coated steel tube used to protect and route electrical cables in buildings and industrial installations. The steel body protects cables from impact and mechanical damage, the zinc coating protects the steel from rust and corrosion, and the metal construction is non-combustible. It is supplied in KBG, JDG, and SC types, with matching fittings, boxes, and accessories.
Key Features
- Corrosion and rust resistance: zinc-coated steel for long service life in building and industrial environments
- Mechanical protection: rigid steel tube protects cables from impact, crushing, and accidental damage
- Non-combustible: steel construction does not feed a fire
- Metal shielding and grounding path: metallic conduit can serve as part of the grounding system when properly connected
- Complete system: couplings, elbows, boxes, clamps, straps, and fixings available from the same supplier
KBG, JDG, and SC: Which Type?
| Type | Wall | Connection | Typical use |
|---|---|---|---|
| KBG | Thin wall | Crimped fittings | Concealed wiring, including embedded in concrete |
| JDG | Thin wall | Set-screw fittings | Indoor concealed and surface wiring; closest to EMT conduit |
| SC | Thick wall | Threaded joints | Locations needing stronger mechanical protection; closest to RMC / IMC conduit |
The three types use different fittings and are not interchangeable, so confirm the type before ordering.
