  3. SL300 Drainage Pipe Line in Europe — Continuous Operation for Road Construction Contractor
April 13, 2026

SL300 Drainage Pipe Line in Europe — Continuous Operation for Road Construction Contractor

Suba Machinery
SL300 Drainage Pipe Line in Europe — Continuous Operation for Road Construction Contractor

Project Context

A European civil construction firm specializing in road and highway projects recognized the competitive advantage of producing their own drainage infrastructure. In 2019, they commissioned a Suba SL300 to supply corrugated HDPE pipe for their internal projects and external sales to public works authorities.

Five years later, the machine remains in continuous operation, representing one of Suba's longest-running customer relationships in Western Europe.

Why the SL300

The contractor selected the SL300 because:

  • Compact footprint suitable for on-site installation at project offices
  • Capacity for 800+ m/shift, meeting their project requirements
  • Ability to produce 300–500mm diameter pipe for road and stormwater applications
  • Total cost of ownership under €120,000
  • Proven reliability with minimal downtime

The Order & Installation

Contract signed in Q2 2019. The SL300 arrived in Q4 2019 and was operational by January 2020. Installation was straightforward, requiring only 2 weeks of Suba technical supervision.

Five-Year Track Record

YearAnnual Output (m)UptimeMajor Services
2020180,00088%Initial setup, calibration
2021210,00091%Routine maintenance
2022225,00093%Bearing replacement, software update
2023240,00094%Routine maintenance
2024255,00095%Expansion to 2nd shift

Total production: 1.11 million linear meters of premium drainage pipe over five years. The machine has paid for itself 4+ times over and remains in excellent condition.

Recent Expansion

In Q3 2024, the contractor commissioned a second shift to increase capacity to 1,600+ m/day, taking advantage of growing demand. They are now evaluating a second SL300 unit for a sister location.

Results

The SL300 has become integral to the contractor's business model:

  • Cost savings: Produces pipe at 30% lower cost than buying from external suppliers
  • Quality control: Ensures all pipe meets internal specifications
  • Project scheduling: Ability to produce custom pipe sizes and quantities on-demand
  • Competitive advantage: Differentiated service offering to public authorities
"The Suba SL300 was the best investment we made as a company. Five years of reliable operation, minimal maintenance, exceptional support from Suba. The machine has become so integral to our operations that we can't imagine not having it. We're now planning our second unit." — Managing Director, European Road & Infrastructure Solutions
