The profiles are made of spheroidal graphite cast iron and treated with a cataphoresis (KTL) process for greater resistance to corrosion caused by contact with the surrounding environment.
BIG I nS technical channels, supplied with blind covers already mounted and secured with an M10 (M12 on request) anti-loosening “bolt + nut” system.
The channels feature a male-female interlocking system for better stability during installation and are equipped with extremely smooth internal walls for improved water flow. The porosity of the concrete is extremely low thanks to its high quality, providing very high resistance to water penetration.
The BIG I nS range of self-supporting drainage channels is made of reinforced cast concrete with high compressive strength (minimum required class: C55/67 – fck = 55 N/mm2 and Rck = 67 N/mm2), resistant to freeze/thaw cycles in the presence of stagnant water containing de-icing salts (+R classification according to EN1433) and to weathering (W classification according to EN1433).
BIG I nS channels are available in various nominal sections and modular lengths, including 3-meter elements. This dimensional flexibility ensures wide versatility of use.
