Gratings for drainage
ULMA provides a full range of gratings for drainage which come in various materials and designs.
In addition to drain grates for pedestrian usage (both for outdoor and indoor use) and for vehicles, ULMA is endowed with the widest range of drain grates for major load areas such as ports, docks and airports. ULMA gratings are designed in accordance with European Standard EN-1433 which regulates covering devices, and closure devices for circulation areas used by pedestrians and vehicles and classifies the drain grates into six categories based on their installation site.Materials:
- Nodular Ductile Cast Iron
- Galvanized steel
- Stainless steel
- Polymer Concrete
- Composite
- Cast Stainless Steel
Designs:
- Slotted(Standard-Heelproof)
- Mesh (Standard-Heelproof)
- Perforated
- Slot (single, double and offsetl)
- Solid
- Longitudinal (Heelproof)

What is a slot grating?
Aesthetics and hydraulic capacity
The SINGLE-SLOT GRATING 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. It is an inverted “T” or “L” shaped grating model, that stands out mainly for its aesthetics, since it integrates perfectly in the pavement (either concrete, paving stone or tiles), totally blending in with the urban landscape.
