Drainage Channel Systems from Turkey
Steeling.net supplies polymer, composite, and polyethylene drainage channel systems manufactured by MEA Grup in Turkey to EN 1433 standard. Products cover the full load-class range from A15 (pedestrian) to D400 (standard roads) and are used in surface water management applications across construction, civil infrastructure, logistics, and landscaping. Modular channel systems are available with a choice of compatible grating cover materials and accessories.
Drainage Channel Types
MEA Grup manufactures three main drainage channel body types — polymer concrete, high-density polyethylene (HDPE/HDP), and composite — each suited to different load requirements, installation environments, and chemical exposure conditions. All channel types are designed as modular systems, allowing channels to be connected end-to-end with compatible fittings, end caps, sump boxes, and outlet connectors for complete surface water management installations.
Polymer Drainage Channel
Polymer concrete channel bodies combining the strength of concrete with chemical resistance and lighter weight. High compressive strength for vehicle-trafficked areas. Compatible with steel, cast iron, composite, and FRP grating covers. Load classes B125 to D400.
Ideal for: Roads, car parks, industrial yards, logistics centres, urban streetscapes.
Polyethylene (HDPE) Channel
High-density polyethylene channel body — lightweight, chemical-resistant, and easy to handle and install. Resistant to acids, alkalis, and most industrial cleaning agents. Suitable for pedestrian and light vehicle applications. Load classes A15 to B125.
Ideal for: Pedestrian areas, cycle paths, garden centres, food production facilities, landscaping.
Composite Drainage Channel
Glass fibre reinforced polymer (GRP/FRP) composite channel bodies — fully corrosion-resistant, non-conductive, and with no scrap value (eliminating theft risk). Suitable for electrical substations, coastal environments, and chemically aggressive settings. Load classes A15 to C250.
Ideal for: Electrical infrastructure, coastal and port areas, chemical plants, water treatment facilities.
Technical Specifications
Drainage channels are rated to EN 1433, which defines load classes, geometric tolerances, material requirements, and testing methods for surface drainage channels. The load class of a channel must be matched to the maximum vehicle load expected in the installation area — under-rating a channel in a vehicle zone is a structural safety failure. Channel width (internal) and installed depth are selected based on the required water flow capacity for the catchment area.

EN 1433 Load Classes — Quick Reference
| Class | Test load | Typical installation |
|---|---|---|
| A15 | 15 kN | Pedestrian areas, gardens, roof terraces |
| B125 | 125 kN | Footpaths, residential driveways, car parks |
| C250 | 250 kN | Kerbside, gutters, slow-speed roads |
| D400 | 400 kN | Standard carriageways, public roads |
Complete System Components
Drainage channel systems are supplied as coordinated modular assemblies — not just channel bodies. All components are dimensionally matched to ensure watertight connections and correct hydraulic performance. Ordering channels, covers, and accessories from a single source eliminates compatibility issues and simplifies documentation for project handover.
Applications
Surface drainage channels are used wherever rainwater or wash-down water must be collected and directed to a drain or outlet without pooling on the surface. The channel load class, material, and width are selected based on the volume of water to be managed, the vehicle loads in the area, and the chemical environment — particularly relevant in food production, chemical handling, and coastal settings where standard polymer concrete may not provide sufficient resistance.
| Application | Recommended type | Load class |
|---|---|---|
| Pedestrian plazas and public spaces | Polymer or composite | A15 / B125 |
| Residential driveways and car parks | Polymer or polyethylene | B125 |
| Commercial car parks | Polymer concrete | B125 / C250 |
| Roads and carriageways | Polymer concrete | D400 |
| Industrial yards and logistics centres | Polymer concrete | C250 / D400 |
| Food production facilities | Polyethylene or composite | A15 / B125 |
| Chemical plants and water treatment | Composite (GRP/FRP) | A15–C250 |
| Coastal and port areas | Composite (GRP/FRP) | B125–C250 |
| Electrical substations | Composite (non-conductive) | B125 |
| Landscaping and garden drainage | Polyethylene | A15 |

Frequently Asked Questions
What is the difference between polymer, polyethylene, and composite drainage channels?
Polymer concrete channels offer the highest compressive strength and are the standard choice for vehicle-trafficked areas (B125–D400). Polyethylene (HDPE) channels are lightweight, easy to install, and highly chemical-resistant — suited to pedestrian and food-industry applications (A15–B125). Composite (GRP/FRP) channels are fully corrosion-resistant, non-conductive, and theft-resistant — preferred for electrical, coastal, and chemical environments (A15–C250).
What load class drainage channel do I need for a road or car park?
For standard public roads and carriageways, specify load class D400 (400 kN test load) per EN 1433. For commercial car parks with standard vehicles, B125 or C250 is typically sufficient depending on the vehicle type. For pedestrian-only areas, A15 or B125 is the standard specification. Always confirm the load class with the project structural engineer — specifying an under-rated product in a vehicle area is a safety and liability issue.
Can drainage channels and grating covers be ordered as a complete system?
Yes. Steeling.net supplies drainage channel systems as complete coordinated packages — channel bodies, grating covers (in steel, cast iron, FRP, or composite), end caps, sump boxes, outlet connectors, and installation accessories. Ordering the complete system from one source ensures dimensional compatibility and simplifies project documentation and handover.
What grating cover materials are available for these drainage channels?
Grating covers are available in hot-dip galvanized steel, stainless steel, cast iron, FRP (glass fibre composite), and high-density composite, depending on the channel type and load class. The grating cover must be rated to the same or higher load class as the channel body. Cover selection also depends on the surface environment — stainless or FRP for hygienic applications, cast iron for heavy road use, composite where theft resistance is a priority.
Are the drainage channels certified to EN 1433?
Yes. All drainage channel products are manufactured to EN 1433 (Linear drainage systems for surface drainage), which defines load classes, hydraulic performance, geometric tolerances, and material requirements. Full EN 1433 certification documentation is provided with product supply. ISO 9001 quality management certification is held by the manufacturing partner MEA Grup.
What is the minimum order quantity and lead time?
There is no fixed minimum order quantity — Steeling.net accommodates both project-specific orders and recurring supply programmes. Lead times vary by product type and quantity; standard products are typically available within 3–6 weeks of order confirmation including production and logistics. Lead time and pricing are confirmed per enquiry.
