Ferroflex® - Fenner Dunlop Conveyor Belting

Steel Fabric Reinforced Belts



Fenner Dunlop Ferroflex has a tension layer composed of longitudinal steel cords through which power transmission is effected. The transverse steel cords reinforce the belt and protect against impact and tears. This well-proven carcass construction has particularly good 'low elongation' characteristics. Ferroflex is an excellent, highly durable solution wherever tensile strength and cover grade qualities need to be adaptable to meet demanding service conditions. This applies to all areas of bulk material handling, particularly long distance applications and high impact conditions.

There are two Ferroflex constructions available, which are referred to as ‘FIW’ and ‘FSW’. The FIW carcass has a single transversal layer of steel cords on top of the longitudinal steel cords, whereas the FSW has two transversal layers of steel cords situated at both sides of the longitudinal steel cords.


Ferroflex provides top-class reliability and durability in a wide cross-section of industries including cement, quarries, wood, paper and pulp, recycling, steel, and transshipment. The FSW reinforced belt can be supplied with cable-free zones to make the installation of buckets and fasteners easier and to create a dynamically stronger belt that is ideally suited as an elevator belt where it is used in combination with the high heat resistant Deltahete rubber covers for the conveying of hot materials.


Ferroflex FIW and FSW belts are custom made to order and can be supplied in all Fenner Dunlop cover grades. All Ferroflex belts are supplied with moulded rubber edges. Available in widths from 500mm up to 2000mm. Tensile strengths (N/mm) : 500, 630, 800, 1000, 1250, 1600 and 2000.
