Steel Cord Conveyor Belt

Our steel cord conveyor belt features high tensile strength, low elongation and even cord tension to avoid deviation. Strong rubber cord bonding ensures superior impact resistance and long service life. It suits small pulleys and high load troughing, with X ray internal defect inspection. Various resistant cover rubbers are available. Perfect for long distance bulk transport in mining, ports, steel and metallurgy sectors to cut downtime and costs.

Our steel cord conveyor belt delivers high tensile strength and low elongation with minimal take-up stroke. Even steel cord tension prevents deviation, while robust rubber-cord bonding offers great impact resistance and longer service life. It supports smaller drive pulleys and good troughability for higher loading, with full X-ray inspection for internal flaws. Multiple cover compounds include abrasion, heat, cold, fire and chemical resistant types. Ideal for long-distance bulk material transport in mining, ports, steel mills, cement plants and metallurgy to reduce downtime and operating costs.

 

Key Features

Many onsite issues come from conventional belts: excessive stretching, poor impact resistance, short service cycles and frequent drift. We designed this steel cord belt to solve these real world pain points.

Small Elongation

Once installed, the steel cord core produces minimal stretch under continuous load. You only need limited take up travel. On long conveyor lines, you will seldom re adjust tension, which saves regular maintenance work.

High Tensile Strength

Parallel high strength steel cords act as the load carrying core. The belt can handle heavy bulk cargo and long haul conveying. It copes with sudden tension surges and reduces the risk of belt rupture under high volume production.

Lower Overall Operating Cost

Long service cycle and stable running mean fewer belt change outs and less unplanned stop time. Less tension tuning and fewer onsite failures will bring down your total system cost.

Balanced Steel Cord Tension

We control cord tension precisely in production. Even tension across all internal cords keeps the belt tracking straight. This reduces side drift, material spillage and uneven edge wear during continuous operation.

Works with Small Diameter Pulleys

The steel cord carcass stands up well to repeated flexing. You can run it on relatively small drive pulleys without cord damage or rubber delamination. This allows you to adopt more compact conveyor layouts and save equipment space.

Reliable Cord to Rubber Adhesion

Galvanized steel cords and custom formula rubber are fully vulcanized together. Strong bonding resists impact and friction. It stops cord exposure and layer separation to prolong belt service life.

Good Troughability

Proper lateral flexibility allows the belt to sit well on deep trough idlers. It holds more bulk material per running cycle and helps contain fines and rock, cutting spillage along the conveyor route.

Full X ray Inspection Option

Before delivery, finished belts can receive complete X ray scanning. This test finds hidden problems: internal cord breakage, cord offset and inner voids — issues you cannot spot only by visual check. It avoids unexpected breakdowns once the belt is running on site.

Lightweight Structure for Energy Saving

We optimised the belt construction for high strength without extra weight. Lower belt mass reduces motor load in continuous operation, helping you save power consumption for heavy duty conveying.

 

Rubber Quality

We match cover rubber grades based on your actual working conditions: conveyed material temperature, lump size, drop height and site environment. Even a strong carcass will fail quickly without proper cover rubber protection.

  • Low Rolling resistant: Reduce running resistance for long distance conveyors
  • Oil resistant: For sites with mineral oil or grease contamination
  • Acid & Alkali resistant:Handle materials with chemical corrosion
  • Normal Abrasion resistant: General purpose bulk material handling
  • High Abrasion resistant: For sharp, heavy rock and high impact loading points
  • Flame retardant:For underground mining and fire risk working environment
  • Heat resistant: For hot clinker and high temperature bulk cargo
  • Cold resistant: Stable performance under low temperature outdoor conditions
  • Anti stick:Prevent wet or sticky material from sticking to belt surface

 

Application Scenarios

Steel cord conveyor belts are widely adopted for heavy load long haul bulk transport across different industries:

  • Mining: Open pit and underground ore transport, cope with heavy impact and high tonnage.
  • Ports & Terminals: Coal, mineral and grain bulk handling at dock conveyor systems.
  • Steel Mills & Metallurgy: Transport sinter, ore and other heavy raw materials.
  • Cement Plants: Raw material and clinker conveying; heat resistant covers are available for hot clinker.

 

Adopted Standards

Our steel cord conveyor belts follow widely accepted global standards for quality reference:

  • China: GB/T9770 2013, HG/T3973 2023, MT/T668 2019
  • Germany: DIN2213
  • Australia: AS 1333
  • Japan: JISK 6369

 

Splicing and Installation

Steel cord belt field splicing is high precision work. It must be completed by certified technicians with qualified vulcanising tools and clean working space.

We can provide you practical support:

  • Step by step splicing guides with real onsite photos
  • On site technical training for your maintenance crew
  • Custom pre made splice kits, matched to your belt cord spacing and rubber formula

Splice types include single step, two step and finger splice. Selection depends on belt strength grade and your pulley configuration. Our technical team will review your conveyor layout first and recommend suitable splice type and overlap length for your project.

Points you need to pay attention to during installation:

  • Select pulley lagging with good friction and wear resistance; ceramic or grooved rubber lagging are common choices.
  • Use gradual idler angle transition between flat section and trough section.
  • Fit heavy duty suspended impact beds at loading points. Since steel cord belts barely stretch, impact force will pass directly onto your conveyor steel structure.

 

FAQs

Q: Can I repair a damaged steel cord conveyor belt?

A: Yes. Local cover damage can be fixed by cold repair or hot vulcanisation. Short section splice repair works if steel cord damage is limited to a small area. If damage covers a large range, full splice replacement will be required.

Q: Do steel cord belts need special idlers?

A: Standard heavy duty idlers work for most cases. For deep trough angle or high speed running, install impact idlers at loading zones. Use self aligning idlers for long distance overland conveyor lines.

Q: What is the storage shelf life for steel cord belt rolls?

A: Store rolls indoors, keep away from direct sunlight and ozone pollution. Under proper storage condition, installation can be done within 2 years. We advise stock rotation following FIFO rule. Check cover surface for cracking before installation.

Q: Can this belt be used on reversing conveyors?

A: Yes. But splice design needs to adapt to bidirectional force, and cover rubber should have balanced wear performance. We can suggest proper configuration for reversing working condition.

Q: What is the difference between steel cord belt and fabric conveyor belt?

A: Steel cord belts deliver much higher tensile strength and far lower elongation, fit for long distance, high tonnage conveying. Fabric belts are lighter, used for short to medium distance transport with lower load requirement.

Q: What does ST rating mean for steel cord conveyor belt?

A: ST stands for the nominal tensile strength of steel cord conveyor belt, such as ST1000, ST2000, ST2500. Unit is N/mm. Higher ST value means the belt can bear bigger pulling force.

Sidewall Conveyor Belt Sagging Solutions QBF rubber Free Zone Base Belt Design Extends Service Life by 30%

Sidewall Conveyor Belt Sagging Solutions: QBF rubber Free Zone Base Belt Design Extends Service Life by 30%

Sep 18, 2026

According to industry statistics, up to 80% of sidewall conveyor belt failures occur due to rigidity loss–induced sagging during operation. QBF rubberaddresses this root cause with an innovative “free zone ” base belt design, significantly extending the service life of sidewall conveyor belts. What Is Belt Sagging and Why Does It Shorten Belt Life? Under heavy load, especially on the return run, the base belt often sags due to insufficient transverse rigidity. This sagging triggers a chain of serious issues: Stress concentration – Sagging causes abnormal flexing at the sidewall root as it passes over the drum, concentrating stress in a localized area. Fatigue cracking – Repeated flexing leads to fatigue cracks at the sidewall root, which can develop into through-wall damage. Baffle detachment – Vibration and deformation from sagging transfer to the baffle connection, accelerating adhesive aging and causing baffle loosening or separation. Once sidewall tearing or baffle detachment occurs, the entire sidewall conveyor belt often fails prematurely. Therefore, solving the sagging problem is the key to extending belt service life. Root Cause of Belt Sagging The core cause of sagging lies in structural deficiencies of traditional base belt designs: Insufficient transverse rigidity – Traditional base belts cannot maintain a flat profile under heavy loads or long-span conditions. Unbuffered stress transfer – The sidewall-to-base belt connection lacks a flexible transition, so abnormal sagging stress directly impacts the sidewall root. Accelerated fatigue accumulation – Repeated flexing at stress concentration points causes cracks to grow from micro to macro levels. Understanding these causes makes it clear: simply increasing sidewall thickness or changing the rubber compound is a temporary fix. The solution must start with the base belt structure. Solution: QBF rubber Free Zone Base Belt Design QBF rubber introduces a “free zone ” base belt design to directly target the root cause of sagging. How the free zone  Works Blocks stress transfer – The free zone  acts as a stress buffer, absorbing and isolating abnormal sagging stress before it reaches the sidewall root. Dissipates flexing energy – The flexible edge allows the base belt to adaptively deform as it passes over the drum, spreading concentrated flexing over a larger area. Protects sidewall and baffles – By mitigating the extra load caused by sagging, the risk of fatigue tearing at the sidewall root is greatly reduced, and the baffle adhesive layer no longer suffers excessive vibration stress. Key Advantages of the free zone  Design Advantage Result sidewall tear resistance Eliminates stress concentration points; fatigue life extended by 2–3 times Baffle detachment risk Smoother operation; significantly slower adhesive aging Overall belt service life Comprehensive service life increased by 30% or more   QBF rubber’s Free Zone Base Belt design achieves a leap from “reacting to sagging consequences” to “eliminating the root cause of sagging.” Summary: Eliminate Sagging at the Source for Longer Sidewall Belt Life The sagging problem in heavy-duty sidewall conveyor belts originates in the base belt structure. QBF rubber’s free zone  design solves this industry pain point by blocking stress transfer, dissipating flexing energy, and protecting both sidewall and baffles. If you are experiencing frequent sagging, sidewall tearing, or baffle detachment with your sidewall conveyor belt, contact QBF rubber for professional technical support and customized solutions.
