D400 CLASS DUCTILE IRON MANHOLE COVER

Square inspection manhole with manhole 0600, in ductile iron GJS-500-7 according to UNI EN 1563 (ed, ’04) in class D400 according to UNI EN 124 (Carregiate of roads), suitable for all carriageways with medium traffic with irregular circulation essentially of cars and heavy vehicles at stabilized urban speed (50Km / H), consisting of:
– Square frame dimensionally compatible with all the wells and provided with a support base of such width as to reduce the stresses induced on the underlying well;
– Round lid with non-slip surface, with maximum opening at 110 ° C and accidental anti-wear device;
– Closure system with mechanical locking guaranteed by the elasticity of the material;
– Release seat for opening with a pickaxe (which must have a height of not less than 1m);
– Soundproofing gasket in EPDM insensitive to the action of oxidizing agents, resistant to degradation due to atmospheric aging, resistant to both low and high temperatures (range -55 ° C / 160 ° C), with high resistance to permanent deformation and with high mechanical and elastic characteristics over time, resistant to numerous chemicals and solvents, and impermeable to water;
– Optional anti-theft locks adaptable to the lid;
– Coating with bituminous paint.
