Key Features and Benefits
Concrete-Encased Mechanical Protection
Resists external pressures, crushing, and construction loads very well.
Electrical Safety
Apartment of non-conductive materials, PVC totally removes the risks of electric shock and grounding problems.
Corrosion & Moisture Resistance
EB-20 PVC is not only rust but also degradation-proof, thus, is great for alkaline concrete and moist soil conditions, unlike metal conduits.
Smooth Internal Bore
Makes the pulling of cables safe and hence, it cuts down the labor cost and the risk of cable being damaged.
Heat & UV Resistance
Still functions even in high ambient temperatures of the Gulf region.
Lightweight & Easy Handling
Porting and installing on-site become much easier.
Long Operating Life
Maintenance-free service of several decades is planned which will, therefore, reduce the lifecycle cost.
Applications of PVC Type EB-20 Conduit – 32 mm
Residential building foundations and slabs
Commercial offices and malls
Underground lighting circuits
Control and instrumentation wiring
Low-voltage and communication systems
Parking structures and basements
Utility corridors and duct banks
Municipal and infrastructure projects
