Rough Top Conveyor Belt

Ideal for indoor light-duty conveying, YUFENG Rough Top Conveyor Belt uses a uniform textured surface to create stable friction points for cartons, packages and small finished goods. It helps prevent sliding on inclined conveyors without damaging packaging surfaces, making it a practical choice for assembly lines, automated sorting systems and light industrial transfer equipment.

Material & Production Technology

1. Flexible EP Carcass for Smooth Running

YUFENG Rough Top Conveyor Belt uses lightweight dipped EP multi-ply canvas as the tensile carcass, providing low elongation and good flexibility for conveying systems equipped with small-diameter drive rollers. The upper cover uses modified high-friction rough grain rubber with wear-resistant additives to maintain the surface texture during repeated material contact, while the smooth soft bottom cover helps reduce running resistance and operating noise.

2. Integrated Vulcanization for Stable Surface Texture

The belt is manufactured through a controlled two-layer integrated low-temperature vulcanization process. This production method helps preserve the designed rough grain structure and reduces surface deterioration caused by excessive curing temperatures. The integrated construction also provides consistent bonding between the carcass and rubber layers during continuous operation.

3. Factory Testing for Anti-Slip Performance

Each production batch undergoes friction coefficient, surface wear and flexibility testing before shipment. These inspections verify the belt's traction, surface durability and bending performance, helping ensure consistent anti-slip performance during long-term cyclic conveying.

Field Test Data & Application Validation

1. Higher Surface Traction on Inclined Conveyors

YUFENG completed six months of continuous tracking tests on logistics and electronics workshop conveying lines, comparing Rough Top Belt with conventional smooth flat belts. Under the tested conditions, smooth belts showed friction coefficients below 0.3 and noticeable package sliding when the incline exceeded 12°. YUFENG Rough Top Conveyor Belt maintained a friction coefficient above 0.45 and supported stable conveying on inclines of up to approximately 30° without auxiliary side or surface restraints, depending on the material and operating conditions.

2. Surface Durability During Repeated Conveying

After 100,000 continuous loading cycles, the rough grain surface showed no obvious polishing, while the measured friction loss remained within 10%. The maintained surface texture helps reduce material repositioning and interruptions caused by slipping, improving operational continuity on light-duty automated conveying lines.

3. Proven Performance in Logistics and Light Industry

In an overseas cross-border e-commerce sorting warehouse, conventional smooth belts caused cartons to slide frequently on 22° inclined sorting lines. YUFENG supplied Rough Top Belt for the application, and after 15 months of continuous operation, the grain surface remained intact with carton sliding reduced to nearly zero. The belt has also been used on electronic component assembly lines, food packaging transfer systems and short-distance wood panel conveying, where customers reported smooth operation, low running noise and reduced dependence on additional anti-slip equipment.

Why Choose YUFENG？

1. Purpose-Built Rubber Formulation for Light-Duty Conveying

YUFENG is a professional Rough Top Belt manufacturer with more than 10 years of experience in light industrial anti-slip belt production and export. Our production process covers canvas dipping, rubber compounding and rough surface molding, with strict control of the friction layer. We use purpose-developed rubber compounds for the top surface rather than recycled rubber, helping maintain consistent traction and surface durability.

2. Surface Design Matched to Actual Conveying Conditions

The rough grain depth, rubber hardness and belt structure can be adjusted according to material type, conveying angle and operating conditions. This allows the belt to provide sufficient grip for cartons, packages and light industrial products while reducing excessive surface contact that could cause scratches or marks during transportation.

3. Complete Support from Specification to Delivery

YUFENG provides working-condition analysis, belt size customization, specification matching, factory-direct supply and technical support after installation. Stable production scheduling supports both standard specifications and bulk orders, helping customers maintain reliable conveying performance while reducing maintenance requirements and downtime.

FAQ

1. How is a Rough Top Conveyor Belt different from a smooth flat belt?

The main difference is the surface traction. Smooth belts provide limited friction and can cause cartons, bags and other products to slide on inclined conveyors. YUFENG Rough Top Belt uses an integrally molded textured rubber surface to increase grip and maintain stable conveying on inclines. 

The flexible rough surface is also designed for gentle contact with cartons and plastic workpieces, making it suitable for logistics, packaging and light industrial lines.

2. Can the rough surface and belt dimensions be customized?

Yes. YUFENG supports customization of belt width, length, overall thickness, rough surface thickness and grain configuration. Surface rubber hardness and grain characteristics can also be adjusted according to the conveyed product. Softer formulations can be selected for delicate packages, while reinforced top layers are available for heavier materials and higher-frequency conveying.

3. What incline angle can the Rough Top Belt handle?

The actual conveying angle depends on product weight, surface condition, belt speed and rough surface configuration. Under suitable working conditions, YUFENG Rough Top Conveyor Belt can provide stable conveying for cartons, bags and light granular materials on inclines of up to approximately 30°–35°. For a specific application, our technical team can recommend the appropriate surface structure based on your material and conveyor angle.

4. How should the rough surface be maintained?

Regular cleaning is important for maintaining consistent traction. Remove dust, paper scraps and fine powder that may become embedded between the surface grains. Belt tension, alignment and roller condition should also be checked regularly to prevent uneven wear. Keeping the rough surface clean helps preserve its designed friction performance during long-term operation.

5. Can the belt be used for fragile or appearance-sensitive products?

Yes. The rough top surface can be formulated with different rubber hardness levels according to the conveyed product. For cartons, plastic components and other appearance-sensitive goods, a suitable soft-texture formulation can provide traction without excessive surface pressure. The final specification should be selected according to product weight, packaging material and conveying speed.

6. Do customized belts undergo factory testing?

Yes. Customized Rough Top Belts are inspected according to their specified application requirements. Typical tests include surface friction, abrasion resistance and flexibility evaluation. These checks help verify that the customized belt meets the required anti-slip and operating performance before shipment.

7. What is the warranty period?

YUFENG provides a 12-month warranty under normal operating conditions and proper maintenance. The warranty does not normally cover damage caused by improper installation, sharp objects, excessive loading, chemical exposure outside the specified range or other abnormal operating conditions. For warranty or technical issues, our service team can provide application-based troubleshooting and support.
