Fibre and telecom rollouts across Saudi Arabia depend on a duct network that protects cable, survives decades of buried service, and lets crews pull or blow fibre without damage. Here is how uPVC telecom duct is specified, and where it fits alongside HDPE microduct on Saudi projects.
A telecom duct is not a pressure pipe — it is a protective conduit. Its job is mechanical: shield the cable from crushing loads, rodents, ground movement and future excavation strikes, while presenting a smooth internal bore so fibre or copper can be pulled or air-blown through without abrasion. That changes the specification priorities compared with a water or sewer line.
The properties that matter most are ring stiffness (resistance to crushing under backfill and traffic loading), a low-friction internal bore, joint integrity that keeps groundwater and silt out of the duct run, and colour and marking so the route is identified correctly during future digs. uPVC delivers all four, which is why SAS 254/255 duct is a standard choice for buried cable protection in the Kingdom.
4B Factory manufactures uPVC duct pipe to Saudi Standards SAS 254 and SAS 255. The core parameters a specifier needs:
| Parameter | Specification |
|---|---|
| Standard | SAS 254 / SAS 255 |
| Diameter range | 20–63 mm nominal |
| Colour | Dark grey (telecom/power identification) |
| Standard length | 6 m with socket |
| Joint types | Socket, spigot and dry-fit |
| Primary use | Telephone, fibre and power cable protection |
This is the question that comes up on almost every fibre project, and an honest answer helps you specify the right system rather than force one product everywhere. The two are complementary, not competitors.
uPVC duct is rigid, dimensionally stable and stiff, which makes it well suited to main duct routes, road crossings and last-mile cable protection where crush resistance and a fixed bore matter. HDPE microduct is flexible and comes on long coils, which suits blown-fibre bundles and situations that need continuous runs with few joints — often installed inside a larger uPVC or HDPE sub-duct. Many networks use both: a rigid outer duct for protection and route integrity, with microduct inside carrying the fibre.
| Factor | uPVC Duct | HDPE Microduct |
|---|---|---|
| Rigidity | Rigid, holds shape | Flexible, coiled |
| Crush resistance | High ring stiffness | Depends on wall/support |
| Best for | Main routes, road crossings, cable protection | Blown fibre inside sub-ducts |
| Jointing | Socket / spigot / dry-fit | Push-fit connectors |
| Typical role | Outer protective duct | Inner fibre carrier |
Duct performance is set as much by installation as by the pipe itself. A few points that matter on Kingdom sites:
On Saudi networks, uPVC duct is specified across a range of buried cable applications:
For related buried-cable work, our PVC conduit & duct pipes cover NEMA TC 2 EPC 80-PVC electrical duct, and our full uPVC duct pipe range carries the complete SAS 254/255 size schedule. For the standards background, the Saudi Standards, Metrology and Quality Organization publishes the governing specifications at saso.gov.sa.

4B Factory uPVC duct pipe is manufactured to Saudi Standards SAS 254 and SAS 255, in sizes 20–63 mm and dark grey colour, supplied in 6 m lengths with socket, spigot and dry-fit joints for telephone and power cable protection.
Use rigid uPVC duct for main routes, road crossings and cable protection where crush resistance matters. Use flexible HDPE microduct for blown fibre over long continuous runs, often installed inside a uPVC sub-duct. Many networks combine both.
4B Factory manufactures uPVC duct pipe from 20 mm to 63 mm nominal diameter, to SAS 254/255. Larger sub-duct and cable-protection requirements can be discussed with our technical team for project-specific specification.
Dark grey is a colour-coding convention that identifies telecom and power duct on a buried route. Consistent duct colour helps future excavation crews recognise what service lies below before digging, reducing accidental cable strikes.
Yes. 4B Factory manufactures uPVC telecom duct factory-direct from its Al-Kharj plant and delivers nationwide, with SAS/SASO compliance documentation supplied for STC, contractor and municipal telecom tenders.
