Self-supporting Type I drainage channel according to EN1433. High-quality self-compacting concrete C55/67 with mesh reinforcement. 100% recyclable cast iron and concrete. Resistant to frost, rain, salt, oil, and gasoline, etc. Self-cleaning flow profile (U-shaped). Due to their design, the drainage channels have a built-in resistance of strength class D, 400 kN. The required resistance is guaranteed by the entire structure. The drainage channels have a tongue and groove connection and a recess for a safety joint (SF). For liquid-tight versions, this recess must be sealed. Galvanized steel pins ensure an improved connection and straight-line installation. The top edges of the channel are equipped with integrated edge protection made of galvanized steel, anchored in the concrete. The drainage channel complies with European Standard EN1433. Dimensions: length 300 cm; internal width 44 cm; external width 60 cm; internal height 65 cm; external height 73 cm. The drainage channel has a hydraulic cross-section of 2212 cm²/m. Weight: 1521 kg. Pre-assembled BANANE grating made of ductile cast iron FGS 500-7, length: 75 cm. The grating is supplied bolted to the drainage channel: 2x bolted with stainless steel bolts (i.e., 8x bolted per drainage channel), the stainless steel bolts are anchored in sleeves that are connected to the reinforcement. The slots in the grating are banana-shaped and 30 mm wide. The gratings have diamond-shaped profiles to increase water retention capacity and prevent slippage. The grating complies with load class D, 400 kN, according to European Standard EN 1433. Absorption surface: 2380 cm²/m.
The self-supporting drainage channels allow installation without a lateral concrete casing (only a foundation is required). Installation instructions are available upon request.
