What about Class 4 rigid steel conduit gi conduit?

Lonwow cable management products are designed, manufactured and proven to be capable of withstanding harsh environmental conditions, which include extremes of heat, humidity, salinity and airborne dust particles.

Galvanised Conduit

All Lonwow conduit’s are Hot Dipped Galvanised inside and out to Class 4, the highest level of resistance to corrosion.

Size Range

Lonwow conduit is available in 3.75m lengths – or specially cut-to-length requirements upon request. The range comprises 20, 25 and 32mm, 1½” and 2” diameters. The conduit is externally threaded at both ends and supplied with a coupler at one end. Removable protection end caps are used to prevent thread damage during transportation.


Lonwow conduit conforms to BS 4568/ BSEN 50086/ BSEN 61386. Lonwow steel conduit meets the maximum strength classification in the British Standard and can be formed on site using standard installation equipment. The internal weld bead and galvanising of the bore are strictly controlled to ensure electrical cables can be pulled through the conduit smoothly, without snagging.

Hot Dipped Galvanised to Class 4  

Lonwow Class 4 conduit is Hot Dipped Galvanised, a process where steel products are coated with zinc by immersing them in a molten zinc bath at a temperature of approximately 450 °C. Trace elements of alloying metals such as lead, aluminium and nickel are included to improve fluidity and reduce dross. The alloys also assist in producing a bright silver appearance which becomes dull grey when exposed to the atmosphere. Hot Dipped Galvanising creates a proactive and self-repairing corrosion resistance; zinc reacts in the air and forms zinc carbonate (responsible for the dull grey in appearance), which protects the steel from corrosion.

Lonwow Class 4 conduit is routinely inspected for corrosion, strength and bending and is independently tested by an approved laboratory.

Handling and Storage

Galvanised conduit should be stored in dry conditions with good air circulation to prevent wet stain storage (“white rust”). However, should this occur it can be easily removed and does not affect corrosion resistance.

Binding materials used to make up bundles of conduit are not intended to be used when lifting this product, which should be handled only with approved slings.
