Grate gutter HRI 500-400. Cast iron BANANE grid. L=2.25m. D400KN

The drainage channels are of type I (self-supporting drainage channels) according to the EN1433 standard. The prefabricated U-channels are made of vibrated and reinforced concrete (C 55/67). Due to its design, the drains have a built-in resistance of strength class D, 400 kN. The proposed resistance is guaranteed by the whole. The drain channels have a tongue and groove connection and a recess for a safety joint (SF). If the design is liquid-tight, this recess must be sealed. Galvanized steel pins ensure an improved connection and straight-line installation. The tops of the gutter are equipped with integrated edge protection in galvanized steel, anchored in the concrete. The drainage channel complies with the European Standard EN1433. Dimensions: length 2.25 m; internal width 420/440 mm (bottom/top); outside width 620/600 mm (bottom/top); internal height 400 mm; outside height 480 mm. The drainage channel has a hydraulic section of 1398 cm2/m. Weight 785kg Pre-assembled BANANA grid made of nodular cast iron FGS 500-7, length 75 cm. The grate is supplied bolted to the drainage channel: 2x bolted with stainless steel bolts (in other words, 6x bolted / drainage channel), the stainless steel bolts are anchored in sleeves that are connected to the reinforcement. The slots in the grille are banana-shaped and have a width of 30 mm. The grates are equipped with diamond-shaped profiles to increase the water collection capacity and prevent slipping. The grille complies with load class D, 400 kN according to the European Standard EN 1433. Absorption surface = 2380 cm2/m. The self-supporting drain channels allow installation without a lateral concrete jacket (only a foundation is necessary). Installation manual available on request.
