1.AESTHETIC APPEAL
This innovative system provides an unobtrusive and sleek look that blends seamlessly with surrounding pavement, making it ideal for a variety of projects, from historic areas to new housing developments.
It is ideal for paved areas, natural stone or concrete paving.
2.HYDRAULIC CAPACITY:
This system has the hydraulic capacity to handle large volumes of water, thanks to the open area of the slot grating, which ranges from 150 cm2/ml to 240cm2/ml.
It can combine with ULMA’s domestic, technical and Civil Channels. From Load class A15 to D400 according to Standard EN1433.
3.DURABILITY:
It's also highly durable and requires minimal maintenance, as slot gratings are made from corrosion-resistant materials.
ULMA`s options include the single-slot grating made of galvanized or stainless steel. It has a slot-shaped collection area that can be either single (15 mm wide) or double (26 mm wide).
4.ACCESSIBILITY:
Accessibility is another key advantage, with easy clip-on manhole access for cleaning. Maintenance is a breeze, and the system meets all relevant regulations for stormwater management.
The SLOT DRAINAGE is part of an integral system, consisting of a discrete slot, a channel body and a sump unit for optimal maintenance of the drainage system. The slot grating is an inverted “T” or “L” shaped grating model, that integrates perfectly in the pavement, totally blending in with the urban landscape.
The grating can be single-slot, double-slot for greater hydraulic efficiency or side-slot to install close to walls.
