The document outlines various types of flexible steel conduits, including bare metal, PVC coated, and liquid tight flexible conduits, specifying their construction, materials, applications, and technical data. Key features include high mechanical strength, temperature ratings, and resistance to environmental factors like moisture and corrosion. These conduits are used in industrial settings for lighting, heating, and power distribution under various conditions.

2. BARE METAL FLEXIBLE STEEL CONDUITS
Bare Metal Flexible Steel Conduits are standard Industrial Conduits with Galvanized sheet steel inner
core without PVCu oversheath. Helically wound with single clutch, this conduit is manufactured from
galvanized steel conforming to Z275 specification. The product is supplied in steel self finish. The
conduits are also available in Stainless Steel.
Typical applications of this conduit include lighting, heating and power distribution under raised
floors and for projects requiring exposure to high temperature environs.
Technical Data
High mechanical strength.
BS EN 50086
IP 40 rated
Temperature rating 0 Deg C to 300 Deg C
Class 4 Heavy Duty application
Highly flexible
Brass nickel plated fittings to BS 731

3. PVC COATED FLEXIBLE STEEL CONDUITS
PVC Coated Flexible Steel Conduits are standard industrial conduits with Galvanized sheet steel
inner core and uPVC oversheath.
The inner metal conduit is helically wound with a single clutch that is manufactured from galvanized
sheet steel that conforms to Z275 standards, with a thin walled PVCu oversheath, vacuum shrunk
over the metal conduit.
A single clutch application on the steel inner core allows good crush protection and high flexibility.
The conduits are supplied in Black Colour as standard, with Grey as an option.

Brass nickel plated fittings to BS 731

4. LIQUID TIGHT FLEXIBLE STEEL CONDUIT
Liquid tight PVC coated Metal Flexible Conduits are similar in construction to standard PVC coated
pipes with the difference that there is a further nylon cord intertwined between the interlocked clutch
construction that ensures IP66 protection to the wires run within such flexible conduits.
This is a standard Industrial Conduit with Galvanized sheet steel inner core and PVCu oversheath.
The range exhibits excellent resistance to sudden temperature variations. The conduit is helically
wound with internal double lock metallic clutch manufactured from galvanized steel conforming to
metal with thick smooth walled PVCu oversheath.
The Liquid tight PVC coated Metal Flexible Conduits have a smooth outer PVCu sheath allowing
complete sealing of fittings to conduit. The product is supplied in Black or Grey as per requirement.
