Details
Most common product types include:
- Flood control inlet gratings
- River screens
- Scumboards
- Water level meters
FLOOD CONTROL INLET GRATINGS
Flood control inlets include large gratings, which can be implemented e.g. in PREFAGRID composite. These gratings consist of a composite angle profile outer frame and a moulded grating 60 mm thick. We offer flood control inlet gratings in loading classes B 125 and C 250.
RIVER SCREENS AND BASKETS
Screens consist of pultruded composite profiles. The outer frame is made of ST 50×50/5 square tubes, while the interior has vertical 22 mm bars or tubes (e.g. 32/3). Screening baskets are usually used at sewage pumping station inlets, where they catch large pieces of detritus to protect the pumps. The basket is suspended on two guide rails and equipped with a motorized lifter. The bottom can be hinged to allow easy emptying. The size and fineness of the basket is based on customer specifi cations.

SCUMBOARDS
Scumboards consist of a load-bearing frame made of pultruded composite profiles and interior screens made of 4-6 mm composite plate (manually laminated or sprayed). For scumboards exposed to higher water pressures, the thin plates can be replaced by sandwich plates (which consist of a moulded grating laminated on both sides). We recommend consulting the design of the loadbearing frame with our technical staff .
WATER LEVEL METERS
Water level meters are made of pultruded composite plates 160 mm wide, with mark intervals
of 20 mm. The length and angle from vertical (if required) depend on customer specification. You can purchase only the meter bar for mounting on an existing structure, or a bar mounted on a loadbearing composite U beam [180×60/10].
SHAFT, TANK, AND PUMPING STATION EQUIPMENT
Sewer shafts and pumping stations usually include fittings to enable inspection and maintenance
access to machinery. Due to their dampness resistance, composite materials are ideal for use
in shafts.
