Self-supporting drainage channel Type I according to EN1433. High-quality self-compacting concrete C55/67 with a reinforcement mesh. 100% recyclable cast iron and concrete. Resistant to frost, water, 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 system. 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 cm; internal width 42/44 cm (top/bottom); external width 62/60 cm (top/bottom); Internal height 40 cm; external height 48 cm. The discharge chute has a hydraulic cross-section of 1398 cm²/m. Weight 261 kg
Pre-assembled BANANA grating made of ductile cast iron FGS 500-7, length 75 cm. The grating is supplied bolted to the drainage channel: twice bolted with stainless steel bolts (i.e., twice bolted per drainage channel), 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 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 area = 2380 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.
