Steel Cord Carcass Cross-Section
Galvanised multi-wire steel cord carcass — near-zero elongation under full load
Application

The steel cord conveyor belt is engineered for the world's most demanding industries — delivering reliable, uninterrupted material flow where fabric belts simply cannot keep pace. Widely deployed in mining, port operations, metallurgy, power plants and chemical processing, it thrives where loads are heavy, distances are long, and downtime is not an option.

Product Structure

Engineered with a five-layer composite architecture — top cover, bottom cover, steel cord carcass, skim rubber, and edge rubber — each layer is precision-bonded using high-adhesion vulcanisation. The galvanised steel cord carcass transmits tensile loads with near-zero elongation, giving your conveyor system dimensional stability across multi-kilometre distances.

Product Benefits
High tensile strength
Good resilience
Impact resistance
High abrasion resistance
Excellent adhesion
Low elongation
Good flexibility & troughability
Extended service intervals

Ideal for conveying lump and granulate materials under heavy duty, long distance, and high-capacity conditions — reducing planned replacement frequency and total belt cost per tonne.
