Polymer Concrete Channel Systems and Size Selection
Integrated Solutions with FRP Composite GratingsPolymer concrete channels are modular trough- or trench-shaped bodies forming a drainage line, suitable for indoor and outdoor environments. Combined with FRP grating, they provide a prefabricated system with rapid installation, coordinated function and a consistent visual finish. Selection is not based on channel width alone: the water or other liquid, flow rate, load, channel size, upper grating, surrounding site detail and maintenance plan must be considered together. The table below lists every A/B/C/D dimension in the 125–400 mm width series so that the body size can be reviewed before the seating, frame and grating details are technically verified.
System Construction and Performance
Polyester-resin and silica-sand composition
The polymer concrete body is manufactured with polyester resin and silica sand in place of cement. It is three times stronger than a conventional concrete channel and significantly lighter. Combining high strength with lower weight supports easier transport and site positioning.
Flow, resistance and rapid installation
The high-precision moulded, smooth internal surface improves water and waste flow, self-cleans and does not retain sediment. Suitable elements and a sloped design help long channels empty more quickly. Resistance to chemicals, freeze–thaw cycles, UV exposure and corrosion, together with the sealing approach, supports a durable drainage line. Fast moulded production and the modular/interlocking structure speed installation, removing site formwork and concrete labour. When coordinated with FRP grating, the result is a channel-and-grating system unaffected by corrosion.
Polymer Concrete Channel A/B/C/D Dimensions
All dimensions are in millimetres. A is the width series, B is the 1,000 mm channel length, C is the channel height and D is the wall dimension. Verify the final seating and upper-grating detail against the project.

How to Coordinate the Channel and Upper Grating
| Project input | Effect on selection |
|---|---|
| Load and traffic | Requires the channel body, seating detail and upper grating to be verified as one system |
| Conveyed liquid | Water, wastewater, chemicals or waste flow affects material and sealing decisions |
| Flow rate and channel width | Guides review of the A and C dimensions against the collected or conveyed flow |
| Upper grating | FRP, cast or stainless grating must match the seating surface and frame |
| Surroundings and maintenance | Road/pedestrian elevation, unobstructed site arrangement, slope and maintenance plan are coordinated |
Selecting channel width only from flow and the grating only from load can produce a seating mismatch or an incorrect load class. In NA-ME Endüstri polymer concrete channel systems supplied with FRP grating, the seating surface and frame detail are matched at the factory.
A Concise View of Drainage Uses
Polymer concrete channels remove surface water, wastewater and chemical or waste spills quickly, contain them where required, and can carry utility lines. Single or multiple secondary lines, single/double slots and square/round holes are considered for streets, parking areas, airports, buildings, factories, treatment and waste facilities, chemical sites and commercial areas. See FRP grating drainage, manhole and channel applications for the detailed site-use narrative.
A Concise View of Channel-Top Grating Selection
The upper grating may be FRP, cast or stainless. For FRP, slip-resistant and insulating construction, cost-effectiveness and project-specified flame-retardant options can be reviewed; a finer mesh suits pedestrian areas, while a deeper panel is used for vehicle traffic. Review channel-to-grating coordination and stormwater-grating decisions on the existing composite channel and stormwater grating specialist page (Turkish). No English counterpart is currently published, so the destination language is stated explicitly.
Verify the Channel System from Project Data
Share the load and traffic, water or other conveyed liquid, design flow rate, channel width and height, line length, upper-grating preference, site elevation and surrounding detail. The NA-ME Endüstri technical team will review the channel body and upper grating together.
