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 F, 900 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 75 m; internal width 32/34.1 mm (top/bottom); external width 50/48 cm (top/bottom); Internal height 30 cm; external height 37 cm. The drainage channel has a hydraulic cross-section of 804 cm²/m. Weight 191 kg
Pre-assembled BANANE grating made of ductile iron FGS 500-7, length 75 cm. The grating is supplied bolted to the drainage channel: 4 bolts with stainless steel bolts, the stainless steel bolts are anchored in sleeves connected to the reinforcement. The slots in the grating are banana-shaped and 30 mm wide. The grating features diamond-shaped profiles to increase water retention capacity and prevent slippage. The grating complies with load class F, 900 kN, according to European Standard EN 1433. Absorption area = 1540 cm²/m².
The self-supporting drainage channels allow installation without a lateral concrete casing (only a foundation is required). Installation instructions are available upon request.
