Reinforcement properties
Made of high-tensile steel cords and various cover grades (see below). A typical carcass with 7 x 7 hot-galvanised steel cords provides a tensile strength of up to 2,000 N/mm. Also available as 7 x 19 for higher tensile strength (10 000 N/mm).
Standard cords have an elongation of 0.22 - 0.28%. High structural strength and pull-out strength ensure good resistance against fatigue. The open cross-lay design of the cords and the chemical adhesive system ensure that the core rubber penetrates thoroughly, bonds well and protects against corrosion for long-term integrity.
Cover grades
The belts come with various cover grades, all made of high-quality rubber with extremely high resistance to abrasion, cutting and impact and with excellent ageing properties. The choice of cover grade will depend on the application and will also determine the working life of the belt. Matching the right belt to your application means generating less waste in the long run &#; helping you to reach your sustainability targets.
Wear-resistant
Available in X, Y, W grades (and similar) for heavy-wear conveying applications such as bulky, sharp materials like heavy, abrasive rocks. High-quality cover grades are recommended to offer the best protection to the belt carcass.

Heat-resistant
Different types of grades are available for high-temperature applications (T120 and T200) such as clinker, coke, foundry sand and slag. Can be used for transporting material at continuous temperatures of up to 190 °C, with peaks of up to 200 °C
Flame-resistant
Available in flame-resistant grade K to comply with ISO 340. Can be used in tunnel projects but not underground applications.

Aramid reinforcement stops elongation on our round and v-belts.
This allows for use of long-length belts, while at the same time minimising the need for long travel tensioning devices. The maximum allowable load is also higher, especially with our overlap weld.
