Rapidself by ULMA: the evolution of light drainage
Light drainage is evolving: less complexity, better on-site performance. From ease of installation to stock optimisation.
With the new Rapidself range, ULMA Architectural Solutions takes a step forward in the design of light drainage channels, offering a more efficient, simpler solution that is better aligned with real on-site needs.
An evolution designed for those seeking technical performance without unnecessary complexity.
An optimised drainage range to simplify your work
Rapidself has a clear objective: simplification.
Thanks to a streamlined range of references, the new system meets the same requirements with fewer products, making specification, on-site management and distribution more straightforward.
- Less complexity
- Greater project agility
- Improved operational efficiency
We have removed what is unnecessary so you can focus on what matters: fewer references, the same level of responsiveness.

Less stock, greater efficiency: a direct advantage for distribution and on-site operations
One of Rapidself’s key benefits is its direct impact on logistics management.
By reducing the number of references, it delivers:
- Optimised stock levels
- Lower storage costs
- Faster product turnover
A particularly valuable improvement for distributors and construction companies seeking efficiency across the entire supply chain.
Enhanced hydraulic performance: channels with an optimised V-section
The new range incorporates a V-section channel design, key to improving the system’s hydraulic performance.
This design allows for:
- Higher water velocity at low flow rates
- Increased capacity in high-flow conditions
- Improved self-cleaning performance
Rapidself system: faster, screwless installation
One of the range’s major advances is its Rapidself locking system, which eliminates locking bars across the entire domestic range.
- Fast, fully manual locking
- Greater mechanical stability
- Improved load distribution
- Easier maintenance and cleaning
This system not only speeds up installation but also enhances hydraulic efficiency by removing elements that interfere with flow.

Technical design in every detail: engineered for better on-site performance
Rapidself is not just a conceptual evolution, it is an improvement in every detail of the system:
- Smooth internal surface → improved water flow
- No irregularities → prevents turbulence
- Guiding grooves → increased water capture
- Slots compliant with standards → safety and compliance
- Male-female system → fast, precise alignment
- Pre-marked outlets → easier installation
All of this results in a more reliable, more efficient system that is easier to install in real on-site conditions.
A complete light drainage solution
The Rapidself range is available in different configurations to suit a wide range of applications:
- Polymer concrete channels
- Wide range of gratings: cast iron, galvanised steel, stainless steel and composite
