Steel Cord Conveyor Belt: Complete Guide to Types, Specifications, Applications and Selection

Steel cord conveyor belts are designed for demanding bulk material handling applications where high tensile strength, long conveying distances, and reliable continuous operation are required. Compared with textile-reinforced conveyor belts, a steel cord conveyor belt uses longitudinal steel cords as its main reinforcement, making it particularly suitable for high-tension and heavy-duty conveying systems.

For mining, cement, ports, power plants, and other bulk material handling operations, selecting the right belt requires more than simply choosing a higher tensile strength. Belt width, conveyor length, material characteristics, operating conditions, pulley arrangement, cover grade, and splice design should all be considered.

This guide explains the structure, types, specifications, applications, advantages, and selection factors of Steel Cord Conveyor Belt, helping industrial buyers and project engineers make a more informed purchasing decision.

A Steel Cord Conveyor Belt is a rubber conveyor belt reinforced with steel cords arranged primarily in the longitudinal direction.

The steel cords provide the belt with high tensile strength and help control longitudinal elongation under operating tension. The rubber cover protects the reinforcement and provides the working surface required for conveying bulk materials.

In simple terms: A Steel Cord Conveyor Belt is a heavy-duty rubber conveyor belt reinforced with longitudinal steel cords for high-tension and demanding conveying applications.

During operation, the conveyor drive system generates tension in the belt. The longitudinal steel cords carry most of the tensile load, while the rubber matrix holds the cords in position and protects them from the operating environment.

The belt typically consists of several functional layers:

 

1. Top rubber cover
2. Steel cord reinforcement
3. Rubber skim layer
4. Bottom rubber cover

 

Optional transverse reinforcement or additional protective structures

The exact construction varies according to belt specification and application requirements.

Steel cord conveyor belts can be configured for different operating environments and material handling requirements. The main differences typically relate to tensile strength, cover properties, reinforcement design, and application conditions.

Standard Steel Cord Conveyor Belt

These are the most commonly used steel cord conveyor belts. They have a rubber cover to protect the steel cords.Designed for general heavy-duty bulk material handling.

Typical applications include:

Mining

Cement

Quarrying

Power generation

Bulk terminals

Heavy Duty Steel Cord Conveyor Belt

A Heavy Duty Steel Cord Conveyor Belt is designed for applications involving high belt tension, heavy material loads, long conveying distances, or demanding operating conditions.

The exact belt construction should be selected according to the calculated conveyor system requirements rather than simply choosing the highest available tensile strength.

Abrasion-Resistant Steel Cord Conveyor Belt

For highly abrasive materials such as ore, rock, and aggregates, the rubber cover should be selected according to the material and operating conditions.

Possible applications include:

Iron ore

Copper ore

Coal

Limestone

Aggregates

Heat-Resistant Steel Cord Conveyor Belt

For applications involving elevated material or ambient temperatures, a heat-resistant Steel Conveyor Belt  be required.Our conveyor belts are suitable for temperatures ranging from -60 to 200℃.

The most important parameters include:

ST is the tensile strength designation commonly used for steel cord conveyor belts.

For example, designations such as ST1000 or ST2000 indicate a nominal tensile strength designation expressed in N/mm.

However, the correct ST rating should not be selected simply because a higher number appears to provide better performance.

The appropriate rating depends on the calculated operating tension and the complete conveyor system design.

The main difference is the reinforcement structure.

A Steel Cord Conveyor Belt uses steel cords as the primary longitudinal reinforcement, while textile conveyor belts use fabric plies such as EP or NN structures.

Steel cord conveyor belts are mainly deployed in scenarios where standard textile‑reinforced belts cannot deliver enough tensile strength, or when conveyor systems operate under high‑tension working conditions.

Mining and quarrying

Mining operations commonly adopt steel cord conveyor belts to move bulk commodities including coal, iron ore and copper across extended distances. They hold up well in harsh working environments, both underground and in open‑pit mines.

Carry large volumes of bulk materials

Fire‑retardant grades available for underground site safety

Built to resist heavy‑impact damage and tearing

Cement and aggregate processing

Cement works and aggregate processing sites depend heavily on steel cord conveyor belts for reliable transport of limestone, gravel, clinker and other materials.

Good abrasion resistance, performs under wide temperature ranges

Stable belt running cuts down dust generation and material spill‑over

Suited for both raw feed and finished‑product transportation

Power plants and energy production

Coal‑fired and biomass power facilities need tough, heat‑tolerant conveyor belts to move fuel reliably.

Fire‑retardant and heat‑resistant variants on offer

Stable performance under harsh site conditions

Optimised for non‑stop, long‑run conveying tasks

Steel and metallurgical industries

Steel‑making and metallurgical sites demand conveyor belts that cope with intense heat and heavy metallic payloads. Steel cord belts from ContiTech are engineered for these tough operating environments.

Heat‑resistant constructions for hot steel slabs and coils

Robust against sharp, abrasive‑type materials

Supports steady running within foundries and metal‑processing workshops

Ports and bulk handling terminals

Port terminals and bulk‑material handling hubs utilise steel cord conveyor belts to transfer grain, coal, ores and other cargo between vessels, stockyards and transfer points.

Built for high‑throughput, long‑distance material transfer

Corrosion resistance to suit coastal/marine working conditions

Cuts material‑handling cycles and boosts overall operational efficiency

For long conveyor systems, belt tension becomes an important design consideration.

A steel cord structure provides high longitudinal tensile strength while maintaining relatively low longitudinal elongation compared with many textile belt constructions.

This makes steel cord belts particularly suitable for:

• Long-distance conveying
• High-tension systems
• High-capacity bulk transportation
• Large mining projects

Unlike a continuous endless belt, a steel cord conveyor belt used in a large conveyor system normally requires a field splice after installation.

Because the steel cords carry the main tensile load, splice quality is critical to conveyor reliability.

A typical splice process may involve:

• Belt preparation
• Rubber stripping
• Steel cord exposure and preparation
• Cord alignment
• Splice assembly
• Vulcanization
• Cooling and inspection

The exact splice design and procedure should follow the belt construction, manufacturer recommendations, and applicable project requirements.

For industrial buyers, the best belt should be selected according to the conveyor system rather than a single product parameter.

Consider the following factors.

1. Conveying Distance：Longer conveyors generally require more detailed tension and belt construction calculations.

2. Material Characteristics：Consider: Material size,Bulk density,Abrasiveness,Impact,Temperature,Moisture,Chemical exposure
3. Conveyor Capacity：Required capacity affects: Belt width,Belt speed,Belt construction,Required tensile strength
4. Conveyor Tension：The required tensile strength should be based on the actual conveyor system calculation.

5. Cover Grade：Select the rubber cover according to: Abrasion,Heat,Oil,Flame,Other environmental conditions
6. Pulley Diameter：Pulley dimensions should be compatible with the selected belt construction.

7. Splicing Requirements：The belt construction and splice design should be considered together.
