PU PVC Conveyor Belt with Standard Sidewalls

Tianjin Shunnai Conveyor Belt Manufacturing Co., Ltd. is a China PU PVC conveyor belt with standard sidewalls manufacturer integrating R&D, production and service, with its production base located in Tianjin. With more than 15 years of experience in industrial conveyor belts and rubber products, SHUNNAI focuses on providing customized belt solutions for bulk material handling, inclined conveying and clean production environments.

The standard sidewalls are specially designed to prevent material overflow during transportation. By adding flexible corrugated retaining walls on both sides of the base belt, the conveying area is increased while reducing material loss caused by vibration, inclination or uneven feeding. SHUNNAI provides PVC, PU and rubber sidewall solutions according to different working conditions, including food processing, chemical materials, grain handling, fertilizer, mining and packaging industries.

Material Selection

PVC and PU Sidewall Options

Material selection directly affects belt performance. SHUNNAI PVC sidewalls are suitable for applications requiring easy cleaning, chemical resistance and economical operation. They are widely used for grain, fertilizer, food ingredients and light industrial materials.

PU sidewalls provide better abrasion resistance, flexibility and food contact safety performance. They are suitable for industries with higher hygiene requirements, frequent cleaning and direct contact with products.

Rubber Heavy Duty Option

For harsh environments involving impact, sharp materials and continuous loading, rubber sidewalls provide higher tear resistance and mechanical strength. They are commonly used in mining, building materials and heavy industrial conveying systems.

Sidewall Structure

Corrugated Design

The corrugated structure allows the sidewall to expand and compress naturally when passing through rollers and curved sections. Compared with straight sidewalls, the folded structure reduces concentrated stress and lowers the risk of cracking caused by repeated bending.

SHUNNAI adjusts corrugation height, pitch and flexibility according to belt width, pulley diameter and conveying angle, ensuring stable movement during continuous operation.

Bonding Technology

The connection between sidewall and base belt determines the service life of the whole conveyor belt. SHUNNAI applies hot vulcanization or high-frequency welding technology according to material characteristics.

The bonding process creates a strong connection between the sidewall and belt surface, preventing separation, peeling and deformation under long-term tension and vibration.

Material Handling Performance

Reducing Product Loss

During transportation, vibration and inclination can easily cause materials to move toward belt edges. Standard sidewalls create a controlled conveying channel, keeping materials within the effective loading area and reducing unnecessary waste.

This design is especially valuable for powder, granular and small-sized materials where even small leakage can increase cleaning costs and production losses.

Improving Line Layout

By preventing side leakage, PU PVC Conveyor Belt with Standard Sidewalls allows conveyors to operate at higher angles compared with traditional flat belts. This helps factories reduce equipment footprint and optimize production space.

When combined with cleats, the belt can achieve stronger lifting capability for inclined conveying applications.

Installation Options

New Belt Production

For new conveyor systems, SHUNNAI can manufacture the belt and sidewalls as an integrated structure. This method provides stronger bonding performance and better dimensional consistency.

Belt Modification

For existing conveyor lines, additional sidewalls can be installed through secondary vulcanization or welding according to belt material. This provides a practical upgrade solution without replacing the complete conveyor system.

Application Examples

A large stone yard: On an 800mm sand/stone line, severe spillage required two workers shoveling daily. After adding SHUNNAI rubber sidewalls (80mm height, 50mm corrugation pitch), spillage reduced approximately 90%, cleaning frequency decreased to once a week, and the investment was recovered within six months.

A fertilizer plant: Urea granules conveying generated dust, with fertilizer pellets rolling off the unprotected belt, causing waste and equipment corrosion. Custom SHUNNAI PVC sidewalls (50mm height, white food-grade) improved workplace cleanliness, reduced material loss and simplified cleaning.

Specification Customization

SHUNNAI provides customized PU PVC Conveyor Belt with Standard Sidewalls solutions according to actual operating conditions. Customers can specify belt width, thickness, sidewall height, corrugation pitch, material type, color, operating temperature and conveying materials.

Sidewall height is available from 30mm to 200mm. Different combinations of sidewalls and cleats can be designed for horizontal conveying, inclined conveying and lifting applications.

FAQ

What is the function of standard sidewalls on a conveyor belt?

Standard sidewalls create retaining barriers on both sides of the belt, preventing materials from falling during transportation and improving conveying efficiency, especially for inclined or bulk material handling.

What materials are available for sidewalls?

SHUNNAI provides PVC, PU and rubber sidewalls. PVC and PU are suitable for food-grade and light industrial applications, while rubber sidewalls are recommended for heavy-duty environments requiring higher wear resistance.

Can sidewalls be added to an existing conveyor belt?

Yes. SHUNNAI can provide secondary vulcanization or welding solutions depending on the existing belt material and operating conditions.

How high can the sidewall be customized?

Sidewall height can be customized from 30mm to 200mm according to material characteristics, conveying angle and required loading capacity.

Is this PU PVC Conveyor Belt with Standard Sidewalls suitable for food processing?

Yes. SHUNNAI offers PU and PVC food-grade sidewall belt solutions with smooth surfaces, easy cleaning performance and FDA-related certification support for suitable applications.
