A national fiber broadband rollout required laying fiber-optic cable across rural and suburban zones. A local construction contractor won a multi-year framework agreement to install conduit — OD 110mm HDPE double-wall corrugated pipe — across 12 provinces.
The volumes were substantial: estimated 40 million meters over 4 years. At those quantities, importing finished pipe was not viable. The contractor decided to invest in in-house production.
The contractor's operations manager evaluated five production line suppliers over three months. The SL110 was selected for the following reasons:
Contract signed in November 2021. The specified configuration:
The coiler and packaging unit were a Suba custom option, enabling the contractor to deliver pre-coiled 50m drums directly to installation crews — eliminating an intermediate packaging step.
Lead time: 10 weeks from contract to FAT at Qingzhou.
2×20ft containers, Qingdao to the destination port, 28-day transit. The contractor arranged truck delivery to their facility. No customs surprises — Suba's documentation team prepared all CE declarations and packing lists in English and local language.
Suba sent one mechanical engineer and one electrical/PLC specialist for the 10-day commissioning visit.
Highlights:
The line has been in continuous operation since Q1 2022. The contractor now runs 3 shifts, 5 days per week:
| Metric | Value |
|---|---|
| Annual production | ~23 million meters |
| Average output | 205 kg/h per shift |
| Coil reject rate | <0.3% |
| Unplanned downtime | <1.5% |
In 2023 the contractor added a second SL110 line from Suba to meet increased order volume, bringing total annual capacity to 46 million meters.
Suba's remote diagnostics module has resolved two PLC issues without requiring an on-site visit — a significant saving given international travel logistics.
*"The second line was an easy decision. The first line ran 22 months without a single major breakdown. When we need spare parts, they arrive in 5 days. Suba is a reliable long-term partner."*

A South Asian manufacturer installed the Suba SL180 to produce small-diameter corrugated HDPE conduit for telecom and electrical cable protection, serving a national fiber rollout program.
Multiple SL300 installations across South Asia supply corrugated HDPE pipe for drainage, sewage, and road construction infrastructure across the region.
A European civil engineering contractor has run a Suba SL300 corrugated pipe line for five years, supplying drainage pipe for road construction and stormwater management projects.
