BIG I nS with cast-iron Z-shaped profile

Self-supporting channels made of high-grade reinforced concrete with spheroidal cast iron profiles
BIG I nS channels, with a wall thickness of 75mm, are provided with reinforcement profiles and protection against wear due to traffic, perfectly anchored to the concrete body in order to prevent their detachment during operation.
The profiles, made of cast iron and therefore resistant to corrosion caused by contact with the surrounding environment, convey extra compactness to the product and greater stability to the gratings.

The fact that they are Z-shaped ensures they fully cover and wrap around the channel and give the entire assembly a very long life span while at the same time making installation easier and safer.
The channels are fitted with male-female joints for better stability during installation and feature extremely smooth internal walls for better water flow. The porosity of the concrete is extremely reduced thanks to its high quality, making it highly resistant to water penetration.
The range conforms to European Standard EN1433 up to class F900/ Type I and bears the mandatoryy CE mark. BIG I nS channels, supplied with gratings already-mounted and fastened with M10 (on request M12) “screw + nut”, security system, are ideal for use in areas with all types of traffic, up to the heaviest and most intense, such as installations along roads and motorways, road crossings, underpasses, port quays or logistics hubs, airports.
BIG I nS channels are available in various internal dimensions, i.e. with clear openings from 200 mm up to 500 mm, for each of which two different heights are available. The largest size, 500×600 mm, ensures a large storage capacity, useful where it is not possible to manage the flow of the collected water through a large number of drains.
The standard length of the products is 3 metres or 1 metre and all of them feature special lifting nails for handling during loading/unloading and installation.
Matching gratings are available in classes from D400 to F900, in the spheroidal cast iron slotted version. Products with pre-installed drains can be made to order.

The BIG I nS range of selfsupporting drainage channels is made of reinforced cast concrete with high compressive strength (minimum class required:
D400-E600 C40/50 – F_ck = 40 N/mm² and R_ck = 50 N/mm²– F900 C55/67 – F_ck = 55 N/mm² and R_ck = 67 N/mm²), resistance to frost/thaw cycles in the presence of stagnant water containing de-icing salts (+R classification according to EN1433) and to aggression due to atmospheric agents (W classification according to EN1433).
